Ford Mondeo (petrol engines). Manual - part 16
3 Clean the seal housing and crankshaft,
polishing off any burrs or raised edges, which
may have caused the seal to fail in the first
place.
4 Refit the oil pump (see Section 16). Grease
the lips and periphery of the new seal, to ease
installation.
5 To fit a new seal, Ford recommend the use
of their service tool 21-093A, with the
crankshaft pulley bolt, to draw the seal into
place; an alternative can be arranged using a
socket of suitable size, with a washer to
match the crankshaft pulley bolt (see
illustration).
6 If such tools are not available, press the
seal squarely into place by hand; tap it in until
it is flush with the pump housing, using a soft-
faced mallet and a socket with an outside
diameter only slightly smaller than the seal’s
(see illustration). This approach requires
great care, to ensure that the seal is fitted
squarely, without distortion or damage.
7 Wash off any traces of oil. The remainder of
reassembly is the reverse of the removal
procedure, referring to the relevant text for
details where required. Check for signs of oil
leakage when the engine is restarted.

8 Remove the transmission (see the relevant
Part of Chapter 7).
9 Where appropriate, remove the clutch
(Chapter 8).
10 Unbolt the flywheel/driveplate (see
Section 21).
11 Remove the sump (see Section 15).
12 Unbolt the oil seal carrier (see
illustration). Remove and discard its gasket.
13 Supporting the carrier evenly on wooden
blocks, drive the oil seal out of the carrier
from behind (see illustration).
14 Clean the seal housing and crankshaft,
polishing off any burrs or raised edges, which
may have caused the seal to fail in the first
place. Clean also the mating surfaces of the
cylinder block/crankcase and carrier, using a
scraper to remove all traces of the old gasket
- be careful not to scratch or damage the
material of either - then use a suitable solvent
to degrease them.
15 Use grease to stick the new gasket in
place on the cylinder block/crankcase, then
offer up the carrier (see illustration).
16 Using a suitable straight edge and feeler
gauges, check that the carrier is both centred
exactly around the crankshaft, and aligned
squarely so that its (sump) mating surface is
exactly the same amount - between 0.3 and
0.8 mm - below that of the cylinder
block/crankcase on each side of the
crankshaft. Being careful not to disturb the
gasket, move the carrier into the correct
position, and tighten its bolts to the specified
torque wrench setting (see illustration).
17 Check that the carrier is correctly located;
if necessary, unbolt it again, and repeat the
full procedure to ensure that the carrier is
correctly aligned.
18 Ford’s recommended method of seal
fitting is to use service tool 21-141, with two
flywheel bolts to draw the seal into place. If
this is not available, make up a guide from a
thin sheet of plastic or similar, lubricate the
lips of the new seal and the crankshaft
shoulder with grease, then offer up the seal,
with the guide feeding the seal’s lips over the
crankshaft shoulder (see illustration). Press
the seal evenly into its housing by hand only,
and use a soft-faced mallet gently to tap it
into place until it is flush with the surrounding
housing.
19 Wipe off any surplus oil or grease; the
remainder of the reassembly procedure is the
reverse of dismantling, referring to the
relevant text for details where required.
Check for signs of oil leakage when the
engine is restarted.
