Main bearings
To remove and to fit
(with the crankshaft in position)
14-8
If the rear main bearing is to be removed with the
crankshaft in position, the flywheel, the flywheel
housing, the rear oil seal housing and the bridge piece
will have to be removed.
Except for engines with a balancer unit fitted, the front
main bearing can only be removed if a suitable
spanner is available that will enable the torque to be
applied correctly to the setscrews of the main bearing
cap. If a suitable spanner is available, the front main
bearing cap can be removed together with the oil
pump. For six cylinder engines, it will be necessary to
remove the suction pipe and strainer and the delivery
pipe. For four cylinder engines, either the balancer
unit or the suction pipe and strainer, the delivery pipe
and the relief valve will have to be removed.
To remove
1 Drain the lubricating oil and remove the sump, see
operation 19-3.
2 Remove all necessary components to get access to
the specific bearing cap.
3 Release the setscrews of the bearing cap and
remove the bearing cap. Remove the lower half of the
shell bearing from the cap.
4 With a suitable tool (A1), push the upper half of the
shell bearing from the side opposite to the location tag
(A2) to remove the bearing tag from its recess (A3) in
the bearing housing. Carefully rotate the crankshaft to
release the bearing from its housing. Keep the
bearing halves in their relevant positions.
