belt FORD GRANADA 1985 Service Owner's Manual

1Refit the thermostat and housing.
2Refit the timing belt tensioner if it was
removed, but do not tighten the bolts yet.
3If applicable, screw the cam follower ball-
pins in their correct locations (see
illustration).
4Oil the valve stems and insert the valves in
their correct guides.
5Wrap some adhesive tape over the collet
groove of each valve, then oil the oil seals and
slide them over the valve onto the guides. Use
a suitable metal tube if necessary to press
them onto the guides. Remove the adhesive
tape.
6Working on each valve in turn, fit the valve
spring and cap, then compress the spring with
the compressor and insert the split collets.
Release the compressor and remove it. Tap
the end of the valve stem with a non-metallic
mallet to settle the collets. If tool 21-005-A is
being used, first locate the camshaft in its
bearings.
7Refit the camshaft.1Drive the new oil seal into the camshaft front
bearing location on the cylinder head using a
suitable metal tube or socket (see
illustration). Smear the lip with engine oil.
2Lubricate the bearings with hypoid
SAE 80/90 oil, then carefully insert the camshaft.
3Locate the thrust plate in the camshaft
groove, then insert and tighten the bolts.
4Using feeler blades check that the endfloat
is as given in the Specifications.
5Lubricate the ball-pins with hypoid
SAE 80/90 oil, then fit the cam followers in
their correct locations and retain with the
spring clips. It will be necessary to rotate the
camshaft during this operation.
6Fit the oil supply tube and tighten the bolts.
7Fit the camshaft sprocket backplate and
sprocket. Insert and tighten the bolt while
holding the camshaft stationary with a spanner
on the lug (see illustration).
8Refit the cylinder head.
1Adjust the valve clearances. This work is
easier to carry out on the bench rather than in
the car.
2Turn the engine so that No 1 piston is
approximately 2 cm (0.8 in) before top deadcentre. This precaution will prevent any
damage to open valves.
3Make sure that the faces of the cylinder
block and cylinder head are perfectly clean,
then locate the new gasket on the block
making sure that all the internal holes are
aligned (see illustration). Do not use jointing
compound.
4Turn the camshaft so that the TDC pointer is
aligned with the indentation on the front of the
cylinder head.
5Lower the cylinder head onto the gasket.
The help of an assistant will ensure that the
gasket is not dislodged. Alternatively, make a
couple of guide studs by sawing the heads off
two old cylinder head bolts; remove the studs
when the head is in position.
6Lightly oil the heads and threads of the new
head bolts and insert them into their holes.
7Using the Torx key, tighten the bolts
progressively to the Stage 1 specified torque
in the indicated sequence(see illustration).
8In the same sequence tighten the bolts to
the Stage 2 specified torque.
9Wait five minutes, then tighten the bolts
through the angle specified for Stage 3, still
following the same sequence. (If the engine is
on the bench, it may be preferable to leave this
final stage until after refitting the engine, when
the problem of holding it still will not arise.)
10Refit the rocker cover, using a new gasket.
Make sure that the dovetail sections of the
gasket engage correctly (see illustration).
11Fit the rocker cover bolts and reinforcing
plates. Tighten the bolts as follows, referring to

Stage 1 - Bolts 1 to 6
Stage 2 - Bolts 7 and 8
Stage 3 - Bolts 9 and 10
Stage 4 - Bolts 7 and 8 (again)
12No further tightening of the cylinder head
bolts is required.
13Refit and tension the timing belt as
described in the next Section.
1Fit the camshaft sprocket backplate and
sprocket. Insert the bolt, hold the camshaft or
sprocket and tighten the bolt to the specified
torque. 2Fit the auxiliary shaft sprocket with the ribs
towards the engine. Fit the sprocket bolt and
tighten it to the specified torque,
counterholding the sprocket with a bar
through one of the holes.
3Fit the crankshaft sprocket, chamfered side
inwards.
4Fit the timing belt over the camshaft
sprocket, but do not engage it with the other
sprockets yet. Be careful not to kink the belt. If
the old belt is being refitted, observe the
previously noted running direction (see
illustration).
5Refit the guide washer and the crankshaft
pulley. Fit the bolt and washer and tighten just
enough to seat the pulley, being careful not to
turn the crankshaft (see illustrations).
6Make sure that the TDC pointer on the
camshaft sprocket backplate is still aligned
with the indentation on the cylinder head.
7Turn the crankshaft by the shortest route to
align the TDC notch in the pulley with the
pointer on the oil seal housing.
8If the distributor is fitted, turn the auxiliary
shaft sprocket so that the rotor arm points to
the No 1 HT segment position.
9Fit the timing belt over the sprockets and
round the tensioner. Move the tensioner to
tension the belt roughly and nip up the
tensioner bolts.
10Turn the crankshaft through two full turns
clockwise, then 60°anti-clockwise (so it is
now at 60°BTDC)
11The belt tension should now ideally be
checked by applying Ford tension gauge 21-113to the longest run. Desired gauge readings are:
Used belt - 4 to 5
New belt - 10 to 11
12If the tension gauge is not available, a
rough guide is that belt tension is correct when
the belt can be twisted 90°in the middle of the
longest run with the fingers (see illustration).
13If adjustment of belt tension is necessary,
turn the crankshaft clockwise to bring No 1
cylinder to TDC(see illustration)then slacken
the tensioner bolts and move the tensioner to
increase or decrease belt tension. Tighten the
tensioner bolts.
14Turn the crankshaft 90°clockwise past
TDC, then anti-clockwise back to the 60°
BTDC position. Check the belt tension again.
15Repeat the above procedure until the belt
tension is correct.
16Tighten the tensioner bolts and the
crankshaft pulley bolt to the specified torques
(see illustration).
17Refit the belt cover and tighten its bolts.
18If the engine is in the vehicle, reverse the
preliminary steps given in Section 13.
19Check the ignition timing when the engine
is next run.
Refer to Section 9 and refit the components
listed. Delicate items such as the alternator
and distributor may be left until after the
engine has been refitted, if preferred.

assistant press the brake pedal hard, or by
removing the starter motor and jamming the
ring gear teeth with a lever.
5Unscrew the bolt part way, and use a
suitable legged-puller to draw the crankshaft
pulley off the crankshaft. The legs of the puller
must be suitably shaped to enable them to
rest on the metal surfaces of the pulley.Note:
Do not attempt to remove the pulley with a
puller whose legs contact the rubber surface
of the pulley(see illustrations). Note that a
new crankshaft pulley retaining bolt will be
required for refitting.

14The timing chain, sprockets and tensioner
can now be examined for wear and damage.
15Commence refitting as follows. Note that
coppered links are provided in the timing
chain to assist with refitting, but these can be
difficult to see on a chain which has already
been in service. If possible, position the
coppered links as described during the
following procedure. If the coppered links are
not visible, the chain should still be refitted as
described, but ignore the references to the
coppered links.
16Make sure that the slot for the Woodruff
key in the end of the crankshaft is pointing
vertically downwards. If necessary,
temporarily refit the crankshaft pulley bolt in
order to turn the crankshaft to the required

securing bolt is tightened.
29Refit the oil pump drive chain tensioner,
and tighten the securing bolt to the specified
torque.
30Refit the Woodruff key to the end of the
crankshaft.
31Inspect the oil seal in the lower timing
chain cover. If the oil seal is in good condition,the cover can be refitted as follows, but if the
seal is damaged, or has been leaking, a new
seal should be fitted to the cover. If necessary,
carefully prise the old oil seal from the cover
using a screwdriver, and drive in the new seal
using a suitable metal tube. Make sure that the
seal lip faces into the engine. Note that the oil
seal should be fitted dry. Take care not to
damage the timing chain cover (see
illustration).
32Fit the lower timing chain cover using a
new rubber gasket (see illustration).
33Loosely refit the timing chain cover
securing bolts.
34Refit the crankshaft pulley to the end of the
crankshaft, and draw the pulley onto the
crankshaft using the original securing bolt, at the
same time centering the lower timing chain cover.

42Where applicable, refill the cooling
system.
1Examine all the teeth on the camshaft and
crankshaft sprockets. If the teeth are “hooked”
in appearance, renew the sprockets.
2Examine the chain tensioner plastic
sprocket for wear. If excessive wear is evident,
the complete tensioner assembly must be
renewed as the sprocket cannot be renewed
independently.Note that the tensioner plunger
assembly must be renewed whenever the
timing chain is removed.
3Examine the timing chain for wear. If the
chain has been in operation for a considerable
time, or if when held horizontally (rollers
vertical) it takes on a deeply bowed
appearance, renew it.
Note: The cylinder head must not be removed
when the engine is warm. Refer to the note at
the beginning of the following Section before
proceeding.

34Disconnect the throttle cable from the
operating lever and bracket.
35Disconnect the right-hand exhaust
downpipe from the manifold then remove the
starter motor, the oil filter, and disconnect the
left-hand exhaust downpipe, in that order.
Refer to Part A, Section 8, paragraphs 1 to 8
of this Chapter.
Cylinder head bolts on the V6 engine may
be conventional (hexagon-headed) or Torx
type. The appropriate Torx key will be needed
to deal with the latter.
Before dismantling the engine into its main
components, the following ancillaries can be
removed. The actual items removed, and the
sequence of removal, will depend on the work
to be done.
Distributor and bracket
Spark plugs
Inlet manifold and associated items
Exhaust manifolds
Clutch
Alternator and bracket
Oil pressure switch(see illustration) Temperature gauge sender
Engine bearer arms
Dipstick
If an oil cooler is fitted between the oil filter
and the block, remove it by disconnecting the
coolant hoses and unscrewing the central
sleeve. The cooler and seal can now be
removed. If the threaded bush is removed
from the block (it may come out with the
sleeve) it must be renewed.
The procedure is described for the engine in
the vehicle. With the engine removed, the
preliminary steps can be ignored.
