18Tighten the bolts in the correct sequence
(see illustration)noting the two stages given
in the Specifications. Tighten to the first stage
in a clockwise sequence starting at point ÒAÓ,
then tighten to the second stage in a
clockwise sequence starting at point ÒBÓ.
Tighten to the third stage after the engine has
been running for twenty minutes.
19If the engine is in the vehicle proceed as
follows.
20Carefully lift the crossmember with the
jack, then refit the securing bolts and tighten
to the specified torque.
21Withdraw the jack, then lower the engine
and remove the lifting tackle.
22Where applicable, refit the brake lines to
the crossmember.
23Ensure that the front wheels are pointing
straight ahead and that the steering wheel is
centred, then reconnect the intermediate shaft
to the steering column. Secure the clamp
plate with the bolt.
24Refit the engine mounting bolts andtighten to the specified torque.
25Refit the starter motor.
26Lower the vehicle to the ground.
27Ensure that the sump drain plug is fitted,
then fill the engine with the correct quantity
and grade of oil. If necessary, renew the oil
filter before filling the engine with oil.
28Reconnect the battery negative lead.
29Start the engine and check for leaks
around the sump, and where applicable the oil
filter. When the engine is started, there may
be a delay in the extinguishing of the oil
pressure warning lamp while the system
pressurises.
30Run the engine for twenty minutes then
stop the engine and tighten the sump bolts to
the third stage given in the Specifications,
starting at the point ÒAÓ shown and working
clockwise.
31Check the oil level.
32Dispose of any old engine oil safely. Do
not pour it down a drain - this is illegal and
causes pollution.
Removal
1Remove the sump.
2Unscrew the bolt securing the pick-up tube
and strainer to the cylinder block (see
illustration).
3Using a suitable splined socket, unscrew
the two securing bolts and withdraw the oil
pump and strainer (see illustration).
4If desired, the hexagon-shaped driveshaft
can be withdrawn, but note which way roundit is fitted (see illustration). The driveshaft
engages with the lower end of the distributor
driveshaft.
5Thoroughly clean the mating faces of the oil
pump and cylinder block.
Refitting
6Commence refitting by inserting the oil
pump driveshaft into the cylinder block in its
previously noted position.
7Prime the pump by injecting oil into it and
turning it by hand.
8Fit the pump, insert the securing bolts, and
tighten them to the specified torque.
9Fit the pick-up tube securing bolt and
tighten it.
10Refit the sump.
Note: A new pressure relief valve plug and
pick-up tube gasket will be required for
reassembly.
Dismantling
1If oil pump wear is suspected, check the
cost and availability of new parts and the cost
of a new pump. Examine the pump as
described in this Section and then decide
whether renewal or repair is the best course of
action.
2Unbolt the pick-up tube and strainer.
Recover the gasket.
3Unscrew the three securing bolts and
remove the oil pump cover (see illustration).
