engine compartment.
17Apply the handbrake (if not already done),
jack up the front of the vehicle and support on
axle stands (see “Jacking and Vehicle
Support”).
18Drain the engine oil into a container.
19Remove the starter motor.
20Remove the exhaust downpipe.
21Unscrew the two nuts securing the engine
mountings to the crossmember. Recover the
washers.
22Unscrew and remove the remaining
engine-to-gearbox bolts, noting the location
of the earth strap (see illustration), and
remove the two bolts from the engine adapter
plate (see illustration).
23Working inside the vehicle, place a
wooden block under the clutch pedal to raise
it fully against its stop which will hold the
automatic adjuster pawl clear of the toothed
quadrant.
24Disconnect the clutch cable from the
release arm, and pass the cable through the
bellhousing. Remove the clip securing the
clutch cable to the right-hand engine
mounting bracket. Note the cable routing for
use when refitting.
25Lower the vehicle to the ground, and
support the gearbox with a trolley jack using a
block of wood between the jack and the
gearbox to spread the load.
26Make a final check to ensure that all
relevant wires, pipes and hoses have been
disconnected to facilitate engine removal.
27Attach a suitable hoist to the engine lifting
brackets located at the front and rear of the
cylinder head, and carefully take the weight of
the engine. The engine should be supported
horizontally, ie do not allow it to tilt front to
rear.
28Raise the engine until the engine
mounting studs are clear of the crossmember,
then pull the engine forwards to disconnect it
from the gearbox. Ensure that the gearbox is
adequately supported, and take care not to
strain the gearbox input shaft. It may be
necessary to rock the engine a little to release
it from the gearbox.

Dismantling
1It is best to mount the engine on a
dismantling stand, but if this is not available,
stand the engine on a strong bench at a
comfortable working height. Failing this, it will
have to stripped down on the floor.
2Cleanliness is most important, and if the
engine is dirty, it should be cleaned with
paraffin while keeping it in an upright position.
3Avoid working with the engine directly on a
concrete floor, as grit presents a real source
of trouble.
4As parts are removed, clean them in a
paraffin bath. However, do not immerse parts
with internal oilways in paraffin as it is difficult
to remove, usually requiring a high pressure
hose. Clean oilways with nylon pipe cleaners.
5It is advisable to have suitable containers
available to hold small items according to
their use, as this will help when reassembling
the engine and also prevent possible losses.
6Always obtain a complete set of new
gaskets for use during engine reassembly, but
retain the old gaskets with a view to using
them as a pattern to make a replacement if a
new one is not available.
7Where possible, refit securing nuts, bolts
and washers to their locations after removing
the relevant components. This will help to
protect the threads and will also prevent
possible losses.
8Retain unserviceable components in order
to compare them with the new components
supplied.
9A suitable Torx socket will be required to
remove the oil pump cover securing screws.
10Before dismantling the main engine
components, the following externally mounted
ancillary components can be removed:
Inlet manifold and carburettor
Exhaust manifold
Fuel pump and operating pushrod

Reassembly
12To ensure maximum life with minimum
trouble from a rebuilt engine, not only must
everything be correctly assembled, but it mustalso be spotlessly clean. All oilways must be
clear, and locking washers and spring
washers must be fitted where indicated. Oil all
bearings and other working surfaces
thoroughly with engine oil during assembly.
13Before assembly begins, renew any bolts
or studs with damaged threads.
14Gather together a torque wrench, oil can,
clean rag, and a set of engine gaskets and oil
seals, together with a new oil filter.
15If they have been removed, new cylinder
head bolts, big-end bolts/nuts and new
flywheel bolts will be required.
16After reassembling the main engine
components, refer to paragraph 10 and refit
the ancillary components listed. Delicate
items such as the alternator may be left until
after the engine has been refitted.

1Remove the timing belt and the crankshaft
sprocket and thrustwasher.
2Withdraw the oil seal using an oil seal
removal tool or by drilling the oil seal outer
face and using self-tapping screws and a pair
of grips.
3Clean the oil seal housing, then smear the
lip of a new oil seal with clean engine oil.
4Fit the oil seal using the crankshaft pulley
bolt and a suitable tool similar to that shown
(see illustration).5As the seal is drawn into position, the inner
edge of the seal may be damaged as it passes
over the end of the shaft. To prevent this, as
soon as the seal begins to locate in the
housing remove the tools being used to fit the
seal, and carefully work the inner edge of the
seal over the end of the crankshaft, using a
small screwdriver or similar blunt tool. The
seal can then be pushed home using the tools
described previously (see illustration).
6Refit the thrustwasher, crankshaft sprocket
and timing belt.

2Prise out the oil seal. If necessary, drill the
outer face of the oil seal and use self-tappingscrews and a pair of grips to withdraw the
seal (see illustration).
3Clean the oil seal housing, then fit the new
oil seal using two flywheel/driveplate securing
bolts and a tool similar to that shown (see
illustration). A suitable tool can be
improvised using a narrow strip of metal sheet
bent to form a circle of the correct diameter,
and a large metal disc with appropriate holes
drilled to allow the flywheel/driveplate
securing bolts to pass through. Make sure
that the seal lip faces into the engine and
lightly smear the lip with clean engine oil.
4Refit the flywheel/driveplate.
Note: A new gasket and new sump bolts must
be used when refitting, and suitable sealant will
be required (available from a Ford dealer). Note
that it is preferable to keep the engine upright
until the sump has been removed to prevent
sludge from entering the engine internals.
