of the crankshaft sprocket, and then pull the
belt vertically upright on its right-hand run.
Keep it taut, and engage it with the teeth of
the camshaft sprocket. If the original belt is
being refitted, check that the belt’s direction
of travel is correct, and realign the belt-to-
sprocket marks made during removal, to
ensure that the exact original engagement
positions are retained. When the belt is fully
fitted on the sprockets, check that the
sprocket positions have not altered.
9Carefully manoeuvre the belt around the
tensioner, and engage its teeth with the water
pump sprocket, again ensuring that the TDC
positions of the crankshaft and camshaft
are not disturbed as the belt is finally
located.
10 Refit the lower timing belt cover, and
tighten its retaining bolts to the specified
torque setting. Refit the crankshaft pulley, and
tighten its retaining bolt to the specified
torque setting.
11 To take up belt slack, loosen off the
tensioner and move it towards the front of the
car to apply an initial tension to the belt.
Secure the tensioner in this position, then
remove the flywheel ring gear locking device.
12 Rotate the crankshaft through two full
revolutions in (the normal direction of travel),
returning to the TDC position (camshaft
sprocket-to-cylinder head). Check that the
crankshaft pulley notch is aligned with the
TDC (0) mark on the lower half of the timing
belt cover.
13 Grasp the belt between the thumb and
forefinger, at the midway point between the
crankshaft and camshaft sprockets on the
right-hand side. If the belt tension is correct, it
should just be possible to twist the belt
through 90º at this point (see illustration). To
adjust the belt, loosen off the tensioner
retaining bolts, move the tensioner as
required using a suitable screwdriver as a
lever, then retighten the retaining bolts. Rotate
the crankshaft to settle the belt, then
recheck the tension. It may take two or three
attempts to get the tension correct. On
completion, tighten the tensioner bolts to the
specified torque wrench setting.
14 It should be noted that this setting is
approximate, and the belt tension should be
rechecked by a Ford dealer with the special tensioner-setting tool at the earliest
opportunity.
15
Refit the starter motor (refer to Chap-
ter 5A).
16 Refit the rocker cover (see Section 4) and
the upper timing belt cover (see Section 7).
17 Refit the auxiliary drivebelt, adjust its
tension as described in Chapter 1, then refit
the crankshaft pulley lower cover.
18 On completion, reconnect the battery
earth lead.

Tensioner
1 Set the engine at TDC for No 1 piston on
compression as described in Section 3, then
refer to Section 7 and remove the timing belt
upper cover.
2 Loosen off the two bolts securing the timing
belt tensioner. Using a large screwdriver, prise
the tensioner to one side to release the timing
belt tension.
3 Remove the two tensioner bolts, and
withdraw the tensioner from behind the timing
belt.
4 Check the condition of the tensioner,
ensuring that it rotates smoothly on its
bearings, with no signs of roughness or
excessive free play. Renew the tensioner if in
doubt about its condition.
5 To refit the tensioner, first check that the
engine is still positioned at TDC for No 1
piston on compression, with both the
camshaft and crankshaft sprocket timing
marks correctly aligned as described in
Section 3.
6 Refit the tensioner, guiding it in position
around the timing belt, and secure with the
two bolts. Move the tensioner towards the
front of the car, to apply an initial tension to
the belt. Secure the tensioner in this position.
7 Adjust the timing belt tension as described
in Section 8, paragraphs 12 to 14.
8 Refit the timing belt upper cover on
completion.
Camshaft sprocket
9 Set the engine at TDC for No 1 piston on
compression as described in Section 3, then
refer to Section 7 and remove the timing belt
upper cover.
10 Loosen off the two bolts securing the
timing belt tensioner. Using a large
screwdriver, prise the tensioner to one side to
release the timing belt tension. Slip the timing
belt off the camshaft sprocket.
11 Pass a bar through one of the holes in the
camshaft sprocket to prevent the camshaft
from rotating, then unscrew and remove the
sprocket retaining bolt. Note that this bolt
must be renewed when refitting the camshaft
sprocket. Remove the sprocket, noting the
Woodruff key fitted to the camshaft; if the key
is loose, remove it for safekeeping.
12 Check the condition of the sprocket,
inspecting carefully for any wear grooves,
pitting or scoring around the teeth.
13 Install the Woodruff key, then fit the
camshaft sprocket with a newretaining bolt.
The threads of the bolt should be smeared
with thread-locking compound prior to fitting.
Tighten the retaining bolt to the specified
torque wrench setting (see illustrations).
14 Check that the engine is still positioned at
TDC for No 1 piston on compression, with
both the camshaft and crankshaft sprocket
timing marks correctly aligned as described in
Section 3.
15 Slip the timing belt over the camshaft
sprocket, then move the tensioner towards
the front of the car to apply an initial tension to
the belt. Secure the tensioner in this position.
16 Adjust the timing belt tension as
described in Section 8, paragraphs 12 to 14.
17 Refit the timing belt upper cover on
completion.
Crankshaft sprocket
18 Remove the timing belt as described in
Section 8.
19 The crankshaft sprocket can now be
withdrawn. If it is a tight fit on the crankshaft,
a puller or two large screwdrivers can be used
to release its grip. Withdraw the thrustwasher
and the Woodruff key from the crankshaft.

the crankshaft pulley, then with a spanner
engaged on the crankshaft pulley bolt, turn
the crankshaft over to set the engine at TDC
for No 1 piston on compression (see Sec-
tion 3).
8Remove the camshaft sprocket as
described in Section 9.
9 Extract the camshaft oil seal as described
in Section 10.
10 Before removing the camshaft and its
thrust plate, check and take note of the
amount of camshaft endfloat, using a dial
gauge or feeler gauges. With the camshaft
endfloat measured and noted, unscrew the
two retaining bolts and then extract the
camshaft thrust plate from its pocket at the
front end of the cylinder head (see
illustrations) .
11 On models with a distributorless ignition system, at the rear end of the cylinder head,
pierce the camshaft blanking plug with a
suitable tool, and then lever it out of its
aperture
(see illustrations) .
12 Withdraw the camshaft from the cylinder
head at the rear (distributor/ignition coil) end
(see illustration) . Take care not to damage
the bearings in the cylinder head as the shaft
is withdrawn.
Inspection
13 Clean and inspect the various
components removed for signs of excessive
wear.
14 Examine the camshaft bearing journals
and lobes for damage or wear. If evident, a
new camshaft will be required.
15 Compare the previously-measured
camshaft endfloat with that specified. If the endfloat is outside of the specified tolerance,
the thrust plate must be renewed.
16
The camshaft bearing bore diameters in
the cylinder head should be measured and
checked against the tolerances specified. A
suitable measuring gauge will be required for
this, but if this is not available, check for
excessive movement between the camshaft
journals and the bearings. If the bearings are
found to be unacceptably worn, a new
cylinder head is the only answer, as the
bearings are machined directly into the head.
17 It is seldom that the hydraulic tappets are
badly worn in the cylinder head bores but
again, if the bores are found to be worn
beyond an acceptable level, the cylinder head
must be renewed.
18 If the contact surfaces of the cam lobes
show signs of depression or grooving, they
cannot be renovated by grinding, as the
hardened surface will be removed and the
overall length of the tappet(s) will be reduced.
The self-adjustment point of the tappet will be
exceeded as a result, so that the valve
adjustment will be affected, resulting in noisy
operation. Therefore, renewal of the camshaft
is the only remedy in this case.
19 Inspect the rocker arm contact surfaces
for excessive wear, and renew if necessary
(see illustration) .
Refitting
20Refitting the camshaft and its associated
components is a reversal of the removal
procedure, but note the following special
points.
21 Lubricate the camshaft bearings, the
camshaft and the thrust plate with clean
engine oil prior to fitting them. As the
camshaft is inserted, take care not to damage
the bearings in the cylinder head. Tighten the
camshaft thrust plate retaining bolts to the
specified torque. When the thrust plate bolts
are tightened, make a final check to ensure
that the camshaft endfloat is as specified.
22 A new front oil seal must be fitted after the
camshaft has been installed (see previous
Section for details). It will also be necessary to
insert a new blanking plug into the rear end of
the cylinder head (where applicable). Drive it
squarely into position so that it is flush with
the head (see illustration) .

23Refer to the procedure in Section 9 when
refitting the camshaft sprocket.
24 Refit and tension the timing belt as
described in Section 8.
25 Lubricate the hydraulic tappets with
hypoid oil before refitting them into their
original locations in the cylinder head.
26 Lubricate and refit the rocker arms and
guides in their original sequence, use new
nuts and tighten them to the specified torque
setting. It is essential, before each rocker arm
is installed and its nut tightened, that the
respective cam follower is positioned at its
lowest point (in contact with the cam base
circle). Turn the cam (using the crankshaft
pulley bolt) as necessary to achieve this.
27 Refit the rocker cover as described in
Section 4.
28 Refit the remaining components with
reference to the relevant Sections in this
Chapter or elsewhere in the manual.
29 On completion, reconnect the battery
negative lead.

be fitted on reassembly. Tie the downpipe up
to support it.
18Before it is released and removed, the
cylinder head must first have cooled down to
room temperature (about 20ºC).
19 Unscrew the cylinder head retaining bolts
progressively in the reverse order to that
shown for tightening (see illustration 12.28).
The cylinder head bolts must be discarded
and new bolts obtained for refitting the
cylinder head.
20 Remove the cylinder head complete with
its manifolds. If necessary, grip the manifolds
and rock it free from the location dowels on
the top face of the cylinder block. Do not
attempt to tap it sideways or lever between
the head and the block top face.
21 Remove the cylinder head gasket. This must
always be renewed; it is essential that the
correct type is obtained. Save the old gasket, so
that the identification marks (teeth) can be used
when ordering the new one (see illustration).
Preparation for refitting
22The mating faces of the cylinder head and
cylinder block must be perfectly clean before
refitting the head. Use a hard plastic or wood
scraper to remove all traces of gasket and
carbon; also clean the piston crowns. Take
particular care during the cleaning operations,
as aluminium alloy is easily damaged. Also,
make sure that the carbon is not allowed to
enter the oil and water passages - this is
particularly important for the lubrication
system, as carbon could block the oil supply
to the engine’s components. Using adhesive
tape and paper, seal the water, oil and bolt
holes in the cylinder block.
23 Check the mating surfaces of the cylinder
block and the cylinder head for nicks, deep
scratches and other damage. If slight, they may be removed carefully with a file, but if
excessive, machining may be the only
alternative to renewal.
24
If warpage of the cylinder head gasket
surface is suspected, use a straight-edge to
check it for distortion. Refer to Part D of this
Chapter if necessary.
25 Ensure that new cylinder head bolts are
used when refitting and clean out the bolt
holes in the block. Screwing a bolt into an oil-
filled hole can (in extreme cases) cause the
block to fracture, due to the hydraulic
pressure.
Refitting
26 To prevent the possibility of the valves
and pistons coming into contact as the head
is fitted, turn the crankshaft over to position
No 1 piston approximately 20 mm below its
TDC position in the bore.
27 Locate the cylinder head gasket on the
top face of the cylinder block, locating it over
the dowels. Ensure that the gasket is fitted the
correct way up, as indicated by its “OBEN-
TOP” marking (see illustration) .
28 Lower the cylinder head into position,
ensuring that it fits over the locating dowels,
then insert the new retaining bolts. Hand-
tighten the bolts initially, then tighten them in
the order shown in the four stages to the
specified torque setting (see illustration).
Where possible, use an angular torque setting
gauge attachment tool for accurate tightening
of stages three and four. Alternatively, after
the first two stages, mark the bolt heads with
a dab of quick drying paint, so that the paint
spots all face the same direction. Now tighten
all the bolts in the sequence to the Stage 3
setting, by tightening them through the
specified angle. Finally, angle-tighten all the
bolts through the Stage 4 angle.
29 The camshaft sprocket should be
positioned so that its TDC index mark pointer
is in alignment with the TDC index spot mark
on the front end face of the cylinder head (see
illustration 3.6b).
30 Now turn the crankshaft pulley to bring its
TDC notch in alignment with the TDC (0)
indicator on the front face of the timing belt
cover, taking the shortest route (not vice-
versa) (see illustration 3.6a). 31
Refit the timing belt over the camshaft
sprocket, and then tension the belt as
described in Section 8.
32 The remainder of the refitting procedure is
a reversal of the removal process. Tighten all
fastenings to their specified torque setting
(where given). Refer to the appropriate Parts
of Chapter 4 for details on reconnecting the
fuel and exhaust system components, and to
Chapter 5B for details on reconnecting the
ignition system components. Ensure that all
coolant, fuel, vacuum and electrical
connections are securely made.
33 On completion, refill the cooling system
and top-up the engine oil (see Chapter 1 and
“Weekly Checks” ). When the engine is
restarted, check for any sign of fuel, oil and/or
coolant leakages from the various cylinder
head joints.
13 Sump -
removal and refitting
2
Removal
1 Disconnect the battery negative (earth) lead
(refer to Chapter 5A, Section 1).
2 Drain the engine oil as described in Chapter
1.
3 Chock the rear wheels then jack up the
front of the car and support it on axle stands
(see “Jacking and Vehicle Support” ). Remove
the auxiliary drivebelt lower cover from inside
the right-hand wheel arch.
4 Where fitted, pull free the oxygen sensor
lead multi-plug, and disconnect it. If the
engine has been recently run, take particular
care against burning when working in the area
of the catalytic converter.
5 Undo the retaining nuts, and detach the
exhaust downpipe from the manifold. The
flange gasket must be renewed when
reconnecting. Where applicable, also detach
the downpipe at the rear of the catalytic
converter, and release it from the front
mounting.
6 On XR2i models, remove the front
suspension crossmember as described in
Chapter 10. On all models, undo the nut and

stabiliser bar/exhaust forward mounting
bracket (where fitted) and ease it out of the
way.
7Remove the starter motor as described in
Chapter 5A, then undo the retaining bolts, and
remove the clutch cover plate from the front
face of the bellhousing (see illustration).
8 Progressively unscrew the sump retaining
bolts and remove them. Support and lower
the sump pan, taking care not to spill any oil
remaining in it as it is removed. If the sump is
stuck to the base of the crankcase, prise it
free using a screwdriver, but take care not to
damage the sump flange face. If it is really
stuck in position, check first that all of the
bolts are removed, then cut around the sump
gasket with a sharp knife to help in freeing the
joint.
9 After the sump is removed, further oil will
almost certainly continue to drip down from
within the crankcase, some old newspapers
positioned underneath will soak up the
spillage whilst the sump is removed.
10 Clean the sump of old oil and sludge,
using paraffin or a suitable engine cleaner
solution. Clean any traces of old gasket and
sealer from the mating faces of the sump and
the crankcase.
Refitting
11 Smear a suitable sealing compound onto
the junctions of the crankcase-to-oil seal carrier at the rear and the crankcase-to-oil
pump housing at the front on each side
(see
illustration) .
12 Insert a new rubber seal in the groove in
the rear oil seal carrier and the oil pump case.
As an aid to correct sump alignment when
refitting it, screw ten M6 studs into the
cylinder block, in the positions circled in
illustration 13.14.
13 Fit a new gasket over the studs. Fit the
sump into position, ensuring that the raised
spacers sit in the gasket. Insert the bolts into
the available holes, and finger-tighten them
only at this stage. Now remove the studs and
fit the remaining bolts, again finger-tight.
14 Tighten the sump bolts in a progressive,
numerical sequence to the specified torque
wrench setting (see illustration) .
15 Fit the sump drain plug with a new sealing
washer, and tighten it to the specified torque
wrench setting.
16 Refit the clutch cover plate, the auxiliary
drivebelt lower cover, the front suspension
crossmember, the gearchange mechanism
stabiliser bar/exhaust forward mounting
bracket, and the starter motor with reference
to the relevant Sections and Chapters of this
manual as applicable.
17 Reconnect the exhaust downpipe as
described in Chapter 4E.
18 On completion, lower the vehicle, and fill
the engine with oil as described in Chapter 1.
Reconnect the battery negative lead.
14 Oil pump -
removal and refitting
3
Removal
1 Disconnect the battery negative (earth) lead
(refer to Chapter 5A, Section 1).
2 Remove the auxiliary drivebelt (see Chap-
ter 1).
3 Remove the crankshaft pulley (Section 6),
the timing belt covers (Section 7), the timing
belt, crankshaft sprocket and thrustwasher
(Sections 8 and 9), and the sump (Section 13).
4 Unscrew the retaining nut/bolts and remove
the oil pick-up pipe (see illustration).
5 Unbolt and withdraw the oil pump from the
front face of the engine. Clean the oil pump
for inspection. Refer to Section 15 for the
inspection procedures. The oil seal in the oil
pump housing should always be renewed
(Section 16).
Refitting
6 Before refitting the oil pump and the
associated fittings, clean off the respective
mating faces. A new oil pump gasket must be
obtained, as well as the seals and gaskets for
the other associated components to be
refitted.
7 When refitting the oil pump, precautionary
measures must be taken to avoid the
possibility of damaging the new oil seal as it is
engaged over the shoulder and onto its journal
on the crankshaft. Extract the Woodruff key
from the groove in the crankshaft, then cut a
thin plastic guide which will furl over and
protrude beyond the shoulder of the seal
journal on the crankshaft (see illus-
tration 14.9b) . This will allow the seal to ride
over the step, and avoid damaging the seal lip
as it is pushed into position on the crankshaft.
8 If a new oil pump is being fitted or the old
pump is to be re-used after cleaning and
inspection, first prime the pump by squirting
clean engine oil into it, and simultaneously
rotating the drivegear a few times (see
illustration) .

9Align the pump gear flats with those on the
crankshaft, then fit the oil pump. Check that
the sump mating faces of the oil pump and
the base of the crankcase are flush each side,
then tighten the retaining bolts to the
specified torque setting. Remove the
protective guide (see illustrations) .
10 Refit the oil pick-up tube to the oil pump,
using a new gasket and tighten to the
specified torque.
11 Slide the thrustwasher onto the front end
of the crankshaft, then insert the Woodruff key
into position in the groove in the crankshaft.
The key must be located with its flat edge
parallel with the line of the crankshaft, to
ensure that the crankshaft sprocket slides
fully into position as it is being refitted.
12 Refit the sump, crankshaft sprocket, the
timing belt, timing belt cover and drivebelt
pulley (as described in the appropriate earlier
Sections of this Chapter). Refit and adjust the
drivebelt as described in Chapter 1.
13 On completion, lower the vehicle and
reconnect the battery negative terminal.
15 Oil pump - dismantling,
inspection and reassembly
3
Dismantling
1 The oil pump fitted is a low-friction rotor-
type, driven from the front end of the
crankshaft. Where a high-mileage engine is being reconditioned, it is recommended that a
new oil pump is fitted.
2
To inspect the rotor assembly, first remove
the pump from the engine (Section 14), then
undo the retaining screws and remove the
cover plate (see illustration) . Remove the O-
ring seal.
Inspection
3 Clean the rotors and the inside of the pump
housing, then visually inspect the various
components for signs of excessive wear and
scoring. Check the pump components for
wear using feeler gauges in the same manner
as that described in Part A of this Chapter,
Section 13. Refer to the Specifications at the
start of this Chapter for specific details.
Reassembly
4 When reassembling the pump, ensure that
the inner (driving) and outer (driven) rotors are
located with the corresponding indented
matchmarks facing the same way (see
illustration) .
16Crankshaft oil seals -

Front oil seal
1 Disconnect the battery negative (earth) lead
(refer to Chapter 5A, Section 1).
2 Chock the rear wheels then jack up the front of the car and support it on axle stands
(see
“Jacking and Vehicle Support” ).
3 Remove the auxiliary drivebelt as described
in Chapter 1.
4 Remove the crankshaft pulley (Section 6),
the timing belt covers (Section 7), the timing
belt (Section 8) and crankshaft sprocket,
Woodruff key and thrustwasher (Section 9).
5 The oil seal is now accessible for removal
from the front face of the oil pump housing
(see illustration) . To withdraw the seal, a
hooked tool will be required; if available, use
Ford special tool No 21-096. Take care not to
damage the oil pump housing during removal.
As it is removed, note the fitted orientation of
the seal in its housing.
6 Clean the oil pump housing and the
crankshaft stub, then lubricate the lips of the
new seal and the crankshaft front stub with
clean engine oil.
7 The oil seal should be drawn into position
using the Ford special tool No 21-093A.
Failing this, use a tube of suitable diameter,
with the crankshaft pulley bolt and washers.
Do not hammer the seal into position. To
protect the seal lips as it is fitted onto the
crankshaft, cut a thin sheet of plastic to suit
and furl it round the front of the crankshaft,
over the journal shoulder.
8 When the seal is fully fitted, remove the
special tool (or fabricated tool) and withdraw
the plastic protector. Check that the
crankshaft is still at the TDC position and refit
the Woodruff key, thrustwasher and sprocket.
Refit and tension the timing belt, then refit the
timing belt cover and crankshaft pulley as
described in the appropriate Sections earlier
in this Chapter.
9 Refit and adjust the auxiliary drivebelt as
described in Chapter 1.

its housing. If the seal housing is removed
from the rear face of the engine, the seal can
be removed as described in paragraph 18. As
it is removed, note the direction of fitting, and
take care not to damage the seal housing as
the seal is extracted.
14Clean the seal housing, the crankshaft
rear flange face, and the flywheel/driveplate
mating surfaces.
15 One of two possible methods may be
used to insert the new oil seal, depending on
the tools available.
16 If Ford special service tool No 21-095 is
available, lubricate the seal lips of the seal and
its running face on the crankshaft with clean
engine oil. Position the seal (correctly
orientated) into the special tool, then draw the
seal into the housing using two
flywheel/driveplate securing bolts so that the
seal is against the stop.
17 If the correct Ford service tool is not
available, it will be necessary to remove the oil
seal carrier housing. To do this, first remove
the sump as described in Section 13, then
unscrew the seal housing retaining bolts and
remove the housing from the rear face of the
crankcase.
18 Drive the old seal from the housing by
carefully tapping it from its aperture using a
suitable punch as shown (see illustration). As
it is removed, note the direction of fitting, and
take care not to damage the seal housing as
the seal is extracted.
19 New gaskets will be required for the seal
housing and sump during reassembly. Clean
the mating faces of the seal housing, the
crankcase and sump. Insert the new seal
squarely into its housing. To avoid damaging
the seal or the housing, place a flat piece of
wood across the face of the seal, and
carefully tap or draw the seal into place. Do
not allow the seal to tilt in the housing as it is
being fitted.
20 Lubricate the running surface on the
crankshaft and the oil seal lip with clean
engine oil. Locate a new gasket onto the rear
face of the crankcase, and refit the oil seal
housing and seal. To avoid damaging the lips
of the seal as it is passed over the end of the
crankshaft, cut a thin sheet of plastic to suit
and furl it round the rear flange of the crankshaft so that it protrudes, and press the
seal over it. With the seal in position, withdraw
the plastic protector. Centralise the seal on the
shaft, check that the housing-to-sump flange
faces are flush to the sump face on the base of
the crankcase, then insert and tighten the
housing retaining bolts to the specified torque.
21
Refit the sump with reference to Sec-
tion 13.
22 Refit the flywheel/driveplate as described
in Section 18.
23 Refit the clutch as described in Chapter 6.
24 Refit the engine or transmission, as
applicable.
17 Engine/transmission mountings - renewal
2
1The removal and refitting method for the
transmission bearer and mountings is as
described for HCS engines in Part A, Sec-
tion 15. On XR2i models, it will be necessary
to remove the front suspension crossmember
first (refer to Chapter 10). 2
The engine right-hand mounting is
significantly different to that fitted to HCS
engines, in that it is a two-piece bracket, and
its removal and refitting procedure is detailed
below.
3 First of all support the engine/transmission
assembly as described in Part A, Section 15,
then unscrew and remove the two nuts
securing the two halves of the mounting
bracket assembly.
4 Unscrew and remove the three bolts
securing the engine bracket section to the
cylinder block (see illustration) .
5 Unscrew and remove the mounting
retaining nut and washer from their location
near the suspension strut.
6 Unscrew and remove the mounting side
bolt from under the right-hand wheel arch.
7 Refitting is a reversal of the removal
procedure. Make sure when refitting
engine/transmission mountings, that any
washers and plates removed during the
dismantling process are refitted in their
original sequence. Do not fully tighten any
mounting bolts until they are all located. As
the mounting bolts and nuts are tightened,
check that the mounting rubbers do not twist.

18 Flywheel/driveplate-
removal, inspection and
refitting
3
Removal
1 Access to the flywheel (manual transmission)
or driveplate (automatic transmission) is gained
by first removing the transmission (Chapter 7A
or B). On manual transmission models, remove
the clutch (Chapter 6).
2 Unscrew and remove the six
flywheel/driveplate retaining bolts, and
carefully withdraw the flywheel/driveplate from the rear face of the crankshaft. Take care
not to drop the flywheel, as it is heavy. Note
that the retaining bolts must be renewed when
refitting.
Inspection
3
The inspection procedures for the
flywheel/driveplate are the same as those
described for the HCS engine in Part A of this
Chapter, but note that the grinding procedures
do not apply to automatic transmission
models (the driveplate cannot be reground).
Refitting
4 Check that the mating faces of the flywheel/driveplate and crankshaft are clean
before refitting.
5
Smear the new retaining bolt threads with
thread-locking compound. Fit the
flywheel/driveplate into position on the rear end
face of the crankshaft. Check that all of the bolt
holes in the flywheel/driveplate are in exact
alignment with the corresponding bolt holes in
the crankshaft, then insert the newbolts and
tighten them in a progressive sequence to the
specified torque wrench setting.
6 Refit the clutch (manual transmission
models) as described in Chapter 6.
7 Refit the transmission (according to type) as
described in Chapter 7A or B.

2C•2 Zetec engine in-car repair procedures
1595Ford Fiesta Remake
1 General information
How to use this Chapter
This Part of Chapter 2 is devoted to repair
procedures possible while the engine is still
installed in the vehicle, and includes only the
Specifications relevant to those procedures.
Similar information concerning the 1.3 litre
HCS engines, and the 1.4 and 1.6 litre CVH
and PTE engines, will be found in Parts A
and B of this Chapter respectively. Since these procedures are based on the
assumption that the engine is installed in the
vehicle, if the engine has been removed from
the vehicle and mounted on a stand, some
of the preliminary dismantling steps outlined
will not apply.
Information concerning engine/transmission
removal and refitting, and engine overhaul, can
be found in Part D of this Chapter, which also
includes the Specifications relevant to those
procedures.
Engine description
The Zetec engine, (formerly Zeta), is of
sixteen-valve, double overhead camshaft (DOHC), four-cylinder, in-line type, mounted
transversely at the front of the vehicle, with
the transmission on its left-hand end.
Apart from the plastic timing belt covers
and the cast-iron cylinder block/crankcase, all
major engine castings are of aluminium alloy. The crankshaft runs in five main bearings,
the centre main bearing’s upper half
incorporating thrustwashers to control
crankshaft endfloat. The connecting rods
rotate on horizontally-split bearing shells at
their big-ends. The pistons are attached to the
connecting rods by gudgeon pins which are
an interference fit in the connecting rod small-
end eyes. The aluminium alloy pistons are
procarmanuals.com

fitted with three piston rings: two
compression rings and an oil control ring.
After manufacture, the cylinder bores and
piston skirts are measured and classified into
three grades, which must be carefully
matched together, to ensure the correct
piston/cylinder clearance; no oversizes are
available to permit reboring.The inlet and exhaust valves are each
closed by coil springs; they operate in guides
which are shrink-fitted into the cylinder head,
as are the valve seat inserts. Both camshafts are driven by the same
toothed timing belt, each operating eight
valves via self-adjusting hydraulic tappets,
thus eliminating the need for routine checking
and adjustment of the valve clearances. Each
camshaft rotates in five bearings that are line-
bored directly in the cylinder head and the
(bolted-on) bearing caps; this means that the
bearing caps are not available separately from
the cylinder head, and must not be
interchanged with caps from another engine. The water pump is bolted to the right-hand
end of the cylinder block, inboard of the
timing belt, and is driven with the power
steering pump and alternator by a flat
“polyvee”-type auxiliary drivebelt from the
crankshaft pulley.
When working on this engine, note that
Torx-type (both male and female heads) and
hexagon socket (Allen head) fasteners are
widely used; a good selection of bits, with the
necessary adapters, will be required, so that
these can be unscrewed without damage and,
on reassembly, tightened to the torque
wrench settings specified. Lubrication is by means of an eccentric-
rotor trochoidal pump, which is mounted on
the crankshaft right-hand end, and draws oil
through a strainer located in the sump. The
pump forces oil through an externally-
mounted full-flow cartridge-type filter - on
some versions of the engine, an oil cooler is
fitted to the oil filter mounting, so that clean oil
entering the engine’s galleries is cooled by the
main engine cooling system.
Repair operations possible with
the engine in the car
The following work can be carried out with
the engine in the car:
a) Compression pressure - testing.
b) Cylinder head cover - removal and
refitting.
c) Timing belt covers - removal and refitting.
d) Timing belt - renewal.
e) Timing belt tensioner and sprockets - removal and refitting.
f) Camshaft oil seals - renewal.
g) Camshafts and hydraulic tappets - removal and refitting.
h) Cylinder head - removal and refitting.
i) Cylinder head and pistons - decarbonising.
j) Sump - removal and refitting.
k) Crankshaft oil seals - renewal.
l) Oil pump - removal and refitting. m)
Flywheel/driveplate - removal and
refitting.
n) Engine/transmission mountings - removal and refitting.
Note: It is possible to remove the pistons and
connecting rods (after removing the cylinder
head and sump) without removing the engine.
However, this is not recommended. Work of
this nature is more easily and thoroughly
completed with the engine on the bench, as
described in Chapter 2D.
2 Compression test -
description and interpretation
2
Refer to Section 2 in Part A of this Chapter.
3 Top Dead Centre (TDC) for No 1 piston - locating
2
1Top dead centre (TDC) is the highest point
of the cylinder that each piston reaches as the
crankshaft turns. Each piston reaches its TDC
position at the end of its compression stroke,
and then again at the end of its exhaust
stroke. For the purpose of engine timing, TDC
on the compression stroke for No 1 piston is
used. No 1 cylinder is at the timing belt end of
the engine. Proceed as follows.
2 Disconnect the battery negative (earth) lead
(refer to Chapter 5A, Section 1).
3 Chock the rear wheels then jack up the
front of the car and support it on axle stands
(see “Jacking and Vehicle Support” ). Remove
the right-hand roadwheel.
4 Remove the auxiliary drivebelt cover (see
Chapter 1) to expose the crankshaft pulley
and timing marks.
5 Fit a spanner onto the crankshaft pulley
bolt, and turn the crankshaft in its normal
direction of rotation (clockwise, viewed from
the pulley end). 6
Note the two pairs of notches in the inner
and outer rims of the crankshaft pulley. In the
normal direction of crankshaft rotation the first
pair of notches are irrelevant to the vehicles
covered in this manual, while the second pair
indicate TDC when aligned with the rear edge
of the raised mark on the sump. Rotate the
crankshaft clockwise until the second pair of
notches align with the edge of the sump mark;
use a straight edge extended out from the
sump if greater accuracy is required (see
illustrations) .
7 Nos 1 and 4 cylinders are now at TDC, one
of them on the compression stroke. Remove
the oil filler cap; if No 4 cylinder exhaust cam
lobe is pointing to the rear of the vehicle and
slightly downwards, it is No 1 cylinder that is
correctly positioned. If the lobe is pointing
horizontally forwards, rotate the crankshaft
one full turn (360º) clockwise until the pulley
notches align again, and the lobe is pointing
to the rear and slightly down. No 1 cylinder
will then be at TDC on the compression
stroke.
8 Once No 1 cylinder has been positioned at
TDC on the compression stroke, TDC for any
of the other cylinders can then be located by
rotating the crankshaft clockwise 180º at a
time and following the firing order (see
Specifications).
9 With the engine set at No 1 piston on TDC
compression, refit the drivebelt cover and the
roadwheel, then lower the vehicle and refit the
spark plugs.
