The crankshaft cannot be reconditioned
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 repla-

Check that there is no play in the cups
around the crank disks.
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
order to ensure good lubrication of the
crank bearing among other things.
