FITTING SPECIFIC ELEMENTS IN THE ENGINE

FITTING THE CRANKSHAFT-CONNECTING ROD
BEARINGS
CAUTION:
The crankshaft-connecting rod bearings and seals must
be renewed after each opening of the engine crankcase.
N.B.:
On opening the crankcases, if the bearings remain fitted
to the crankshaft-connecting rod, use a bearing remover
(1).
N.B.:
If the bearing remains in the left-hand crankcase, the
crankcase must be heated up using a heat stripper to re-
lease it.
This operation should be performed quickly, to ensure that
the bearing is removed and refitted in the crankcase.
1)
Turn one of the crankcases over onto its flat joint, heat it
up (to 80 to 90ºC) until the bearing falls out by itself.
2)
Remove the seal.
3)
While the crankcase is still hot and expanded, fit the new bea-
ring fully into its housing.
4)
Fit a new seal into the left-hand crankcase using the tool.
Special tool (G)
CAUTION:
The right-hand side seal must be fi tted after closing the
crankcases, fi tting the O-ring and the spacer, to prevent it
from turning over or damaging the seal rims.
