RE-ASSEMBLY OF THE CRANKSHAFT
|
|
|
|
Prior to assembly, it is vital to polish the
crank journals using a fine grade emery tape then
make absolutely sure that all parts are washed very
thoroughly in gasoline (petrol) until clean. Ensure
also that the oil ways are clean and blown through
with an air line.
|
|
Re-assembly proceeds as below:
|
|
|
|
1
|
Fit the drive side crank cheek to the flywheel,
mating the markings previously made. The reason for
this order of assembly is that the bolts fit drive
side to timing side.
|
|
2
|
Fit the two studs through from drive side to
timing side. Position the locking tab over both of
the, studs from the drive side and fit the nut.
|
|
3
|
Assemble the timing side crank cheek over the
studs and the dowel in the flywheel.
|
|
4
|
Assemble the four remaining bolts, driving side
to timing side, noting that the bolts are a good
fit into the crank cheeks and will in all
probabilty need to be tapped home with a drift.
|
|
5
|
Fit the second tab washer over the studs,
followed by the stud nuts.
|
|
6
|
Tighten the six nuts, commencing with the two
washers and then proceeding diagonally, tighten the
others.
|
|
7
|
Tap over the tab washers or use vice grips to
bend the tabs over.
|
|
8
|
Ensure that the oil way blanking plug is fitted
in the timing side crank cheek, particularly if a
new timing side crank cheek is in use.

RE-ASSEMBLING CONNECTING RODS TO CRANKSHAFT
|
|
|
|
As a matter of practice always use new bearing
shells and at the time of fitting the shells, smear
them with clean engine oil. Proceed as follows:
|
|
|
|
1
|
Press the drilled shell into the connecting rod
big end eye and rotate into position, locating with
the tab.
|
|
2
|
Fit the plain shell into the connecting rod cap
and again locate the tab. The tab positions are
shown in Fig. C33.
|
|
3
|
Fit the connecting rods but before doing so,
note that it is unnecessary to renew the connecting
rod bolts though new nuts should always be used.
The connecting rods must be fitted with the oil
holes from the big end eye outwards in each case.
Fit the end caps with shells, ensuring that the
mating marks align, and tighten the nuts evenly by
hand.
|
|
4
|
Tighten the connecting rod nuts to a torque
reading of 25 Ibs./ft. (3.456 Kg/m).
