the transmission are absolutely clean and
flat. Any shims found on removal of the
sump must be refitted in their original
locations.
b)
Apply a thin film of suitable sealant (Ford
recommend Hylosil 102) to the junctions
of the cylinder block/crankcase with the
oil pump and the crankshaft left-hand oil
seal carrier. Without delay - the sump
bolts must be fully tightened within 10 to
20 minutes of applying the sealant - offer
up the sump and engine/transmission
lower adapter plate, and refit the bolts,
tightening them lightly at first.
c)
Ensuring that the engine/transmission
lower adapter plate is correctly located,
firmly press the sump against the
transmission, and tighten the
transmission-to-sump (ie, engine) bolts to
the specified torque wrench setting.
d)
Without disturbing the position of the
sump, and working in a diagonal
sequence from the centre outwards,
tighten the sump bolts to the specified
torque wrench setting.
e)
Proceed to paragraph 14.
13 If the sump is being refitted with the
engine and transmission separated (in or out
of the vehicle), proceed as follows:
a)
Apply a thin film of suitable sealant (Ford
recommend Hylosil 102) to the junctions
of the cylinder block/crankcase with the
oil pump and the crankshaft left-hand oil
seal carrier (see illustration). Without delay
- the sump bolts must be fully tightened
within 10 to 20 minutes of applying the
sealant - offer up the sump to the cylinder
block/crankcase, and insert the sump
bolts, tightening them lightly at first.
b)
Using a suitable straight edge to check
alignment across the flat-machined faces
of each, move the sump as necessary so
that its left-hand face - including any
shims found on removal - is flush with
that of the cylinder block/crankcase (see
illustration). Without disturbing the
position of the sump, and working in a
diagonal sequence from the centre
outwards, tighten the sump bolts to the
specified torque wrench setting.
c)
Check again that both faces are flush
before proceeding; if necessary, unbolt
the sump again, clean the mating
surfaces, and repeat the full procedure to
ensure that the sump is correctly aligned.
d)
If it is not possible to achieve exact
alignment by moving the sump, shims are
available in thicknesses of 0.25 mm
(colour-coded yellow) or 0.50 mm (colour-
coded black) to eliminate the discrepancy
(see illustration).
14 The remainder of reassembly is the
reverse of the removal procedure, noting the
following points.
a)
Tighten all fasteners to the torque wrench
settings specified.
b)
Always renew any self-locking nuts
disturbed on removal.
c)
Refill the cooling system (see Chapter 1).
d)
Refill the engine with oil, remembering
that you are advised to fit a new filter (see
Chapter 1).
e)
Check for signs of oil or coolant leaks
once the engine has been restarted and
warmed-up to normal operating
temperature.

Removal
Note: While this task is theoretically possible
when the engine is in place in the vehicle, in
practice, it requires so much preliminary
dismantling, and is so difficult to carry out due
to the restricted access, that owners are
advised to remove the engine from the vehicle
first. Note, however, that the oil pump
pressure relief valve can be removed with the
engine in situ - see paragraph 8.
1 Remove the timing belt (see Section 8).
2 Withdraw the crankshaft sprocket and the
thrustwasher behind it, noting which way
round the thrustwasher is fitted (see Sec-
tion 9).
3 Remove the sump (see Section 13).
4 Undo the screws securing the oil pump
pick-up/strainer pipe to the pump, then
unscrew the nut and withdraw the oil pump
pick-up/strainer pipe. Discard the gasket.
5 Unbolt the pump from the cylinder
block/crankcase
(see illustration). Withdraw
and discard the gasket, and remove the
crankshaft right-hand oil seal. Thoroughly
clean and degrease all components,
particularly the mating surfaces of the pump,
the sump, and the cylinder block/crankcase.
Inspection
6 Unscrew the Torx screws, and remove the
pump cover plate; noting any identification
marks on the rotors, withdraw the rotors (see
illustration).
