the pump cover, recover the washer, and
withdraw the spring and plunger (see
illustrations).
6 Thoroughly clean all components in petrol
or paraffin, and wipe dry using a non-fluffy rag.
7 Examine the rotors and the pump casing for
signs of excessive wear on the machined
surfaces. If wear is evident, the complete
pump assembly must be renewed, as spare
parts are not available individually.
8 Commence reassembly by lubricating the
relief valve plunger. Fit the plunger and the
spring, and screw the plug into place, ensuring
that the washer is in place under the plug.
9 Lubricate the rotors, and fit them to the
pump casing with the punch marks facing the
pump cover (see illustration).
10 Refit the pump cover and tighten the
securing bolts.
11 Prime the pump before refitting.
1 Examine all the teeth on the sprockets. If the
teeth are “hooked” in appearance, renew the
sprockets.
2 Examine the chain tensioner for wear and
renew it if necessary.
3 Examine the chain for wear. If it 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: New connecting rod bolts and a new oil
pick-up pipe gasket must be used on refitting.
1 Remove the sump and the cylinder head.
2 Unscrew the two securing bolts, and
remove the oil pick-up pipe (see illustration).
Recover the gasket and discard it.
3 Unscrew the four securing nuts and
withdraw the oil baffle from the studs on the
main bearing caps (see illustration).
4 Removal is as described in Part A, Section 21,
paragraphs 2 to 5 of this Chapter, and refitting
as described in Part A, Section 37, noting the
following additional points:
a)
Take note of the orientation of the bearing
shells during dismantling, and ensure that
they are fitted correctly during reassembly.
b) When fitting the pistons, ensure that the
arrow on the piston crown and the letter F
on the face of the connecting rod are
pointing towards the front of the engine.
c) Use new connecting rod bolts on
reassembly; before fitting, oil the threads
and the contact faces of the bolts. Tighten
the bolts to the three stages given in the
Specifications.
d) Refit the oil baffle and tighten the securing
nuts.
e) Clean the mating faces of the cylinder
block and the oil pick-up pipe, and refit
the pick-up pipe using a new gasket.
f) Refit the cylinder head and the sump.
Note: A new crankshaft rear oil seal and a new
rear oil seal housing gasket should be used on
reassembly.
1 With the engine removed from the vehicle,
remove the timing chain and crankshaft
sprocket, and the flywheel/driveplate.
2 Remove the pistons and connecting rods. If
no work is to be done on the pistons and
connecting rods, there is no need to push the
pistons out of the cylinder bores.
3 Unbolt the crankshaft rear oil seal housing
and remove it from the rear of the cylinder
block. Recover the gasket and discard it.
4 Unscrew the two securing bolts and remove
the sump mounting plate from the front of the
cylinder block (see illustration).
5 Check the main bearing caps for identification
marks, and if necessary use a centre punch to
identify them (see illustration).
6 Before removing the crankshaft, check that
the endfloat is within the specified limits by
inserting a feeler blade between the centre
crankshaft web and one of the thrustwashers
(the thrustwashers are fitted to the crankcase,
not the bearing cap). This will indicate whether
or not new thrustwashers are required.
7 Unscrew the bolts and tap off the main
bearing caps complete with bearing shells.
8 Lift the crankshaft from the cylinder block,
and remove the rear oil seal if it is still in place
on the crankshaft.
