New crankcases are supplied with
preassembled ball bearings and oil
seals. It is necessary to stamp the
machine’s serial number on the
crankcase with 2.5 mm
(0.98 in) figure stamps.
If only the ball bearings have to be
replaced, make sure that the
annular / stop buffers, intake hose
and oil tank cap have been removed
before heating the crankcase.
If the original crankcase is used
again, remove all gasket residue
and clean the mating surfaces
thoroughly to guarantee a perfect
seal.

are required when using a new
crankcase:
– Install the chain brake – b 5.4.3
