Crankshaft and crankcase
Inspect the small end of the connecting
rod.
Check the crank bearing.
Assembly
Mount the bearings in the crankcase
halves.
Fit the sealing rings in the crankcase
halves.
Inspect the small end of the connecting
rod.
If seizure marks or discolouration are
found in the bearing track the crankshaft
must be replaced.
Check the crank bearing. The connecting
rod shall not have any radial play (up and
down).
It should, however, have axial play, in or-
der to ensure good lubrication of the crank
bearing among other things.
Assembly
Mount the bearings in the crankcase
halves.
Heat the crankcase halves to approx.
110°C using a hot air gun. Put the ball-
bearings in position.
Use a suitable punch and hammer, if
needed.
Make sure the bearing rests against the
circlip and shoulder in the bearing seating.
Fit the sealing rings in the crankcase
halves with the help of a suitable punch.
Turn the sealing rings so the abraded
edge faces inwards.
The sealing rings should lie fl ush with the
outer edge of the bearing seating.
