Crankshaft and crankcase
Check the crank bearing. 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.
Check the crankshaft’s bearing and seal-
ing ring holder.
Check for wear on the crankshaft’s bea-
ring.
Replace the bearing complete with sealing
ring holder. If there are heavy indentation
marks in the seal casing the holder must
be replaced as leakage can otherwise oc-
cur between the crankcase and bearing.
If the bearing is free from defects, but the
rubber covering on the sealing ring holder
is damaged the holder can be dismantled
from the bearing.
Carefully saw a slot in the cover with
a hacksaw and pry o the sealing ring
holder.
Assembly
Check the crankshaft as set out in the
section ”Checking the crankshaft”.
Check that there is no play on the spacer
washers (A) around the crank disks.
Fit new bearings on the crankshaft with
the open side facing in towards the crank
disc.
