3.11.9. RECOMPOSITION OF THE CRANKCASE AND
DRIVE SHAFT
•
Position the half-case on two suitable supports. Use a
heat gun to heat the seat of the bearing to about
120°C.
•
Insert the drive shaft until the bearing reaches its end
of travel stops. Make sure the con rod is aligned with
the axis of the cylinder.
•
Reinstall the specific crankcase separation plate. Do
not install the drive shaft guard.
•
Slacken the central thrust bolt during the reassembly
operations. Bring the attachment bolts ot the end of
their travel and then slacken them to the same angle.
•
When the temperature is steady, preload the thrust bolt
of the tool just enough to cancel the play of the balls of
the bearing.
•
Degrease the surface with an appropriate solvent and
apply a thin layer of Loctite.
