Bearings / Crankcase

Each half of the crankcase can be
replaced separately if it is damaged.
New crankcase halves are supplied
with the main parts preassembled
– see the parts list.
Parts not supplied with the new
crankcase must be transferred from
the original crankcase – check the
parts and replace if necessary.
If a new crankcase is installed, the
machine's serial number must be
stamped on it with 2.5 mm figure
stamps.
If the original crankcase is used
again, replace the oil seals and ball
bearings, remove any gasket
residue and clean the sealing
surfaces thoroughly. The sealing
faces must be in good condition and
clean to guarantee a perfect seal.
Inspect both halves of the
crankcase for cracks and all sealing
faces for signs of damage.
