Inspecting the
crankshaft
The crankshaft cannot be reconditio-
ned but must be replaced if it is worn or
damaged.
Inspect the large end of the connecting
rod. If seizure marks, discolouration on
the sides or damaged needle holders are
found the crankshaft must be replaced.
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.
