The crankshaft (1), connecting
rod (2) and needle bearing form
an inseparable unit. This means
that the crankshaft must always
be replaced as a complete unit in
the event of damage to any one
of these parts.
– When fitting a replacement
crankshaft, always install new oil
seals and ball bearings.
– Remove the gasket from the
crankcase sealing face.
Use a screwdriver to pry the oil
seal out of the ball bearing at the
clutch side.
