Installing
Ignition side of crankcase
Take care not to damage the
crankshaft stub.
Inspect and clean the sealing faces
on the ignition side of the
crankcase (including the cylinder
sealing face) – the sealing faces
must not be damaged in any way.
: Position the tapered stub of the
crankshaft (arrow) above the ball
bearing at the ignition side.
– Wear protective gloves
to reduce risk of burn injury.
– Heat the bearing inner race to
about 160°C (320°F).
: Push the crankshaft home as far
as stop.
This operation must be carried out
very quickly because heat is
absorbed by the crankshaft, and the
inner bearing race shrinks.
