Take particular care not to bend the pipes
and/or strain the cables excessively when
tilting the engine assembly.
Support the transmission housing (A) at the end
of the relative shaft to allow some degree of
rotation when inserting the shaft into the
splined hub of the flywheel.
Fit the transmission housing (A), mating the
splining of the relative shaft with the splined
hub of the flywheel, and push completely onto
the crankcase, aligning the respective stud
bolts.
FROM Engine No. 181233, particular care is
necessary during this procedure as there
are two O-rings on the flywheel, each of
which exerting axial resistance during
insertion. After passing the first O-ring (first
point of axial resistance), the axial
resistance encountered remains constant
while the transmission housing is being
pressed into its seat until the second O-ring
is reached (second point of axial
resistance). At this point, apply additional
force to pass the second O-ring (second
point of axial resistance).
Taking particular care not to disengage the
splined shaft of the housing from the splined
hub of the flywheel, separate the housing by
approximately 2 cm and insert again until
completely seated in the crankcase.
Check that the housing (A) is seated completely
on the crankcase, then tighten the indicated
nuts.
Pre-tighten the indicated nuts in the sequence
given.
