14. 1 Service Data
Function of crankcase: It is a bearing component in the engine. It is provided to support the
crankshaft, clutch, gearbox, cylinder block and head, withstand impact from combustion and inertia
force due to crankshaft connecting rod mechanism, and it also forms some enclosed spaces (oil-seal
and gas-seal).
Suspension hole is provided on the crankshaft, and it is connected with the suspension hole on the
motorcycle so that the engine is connected with frame and other parts.
Precautions
Crankcase is thin-wall casting, so it is required to avoid impact during operation for fear of
deformation or breaking.
All parts must be cleaned before being checked, and purged with high-pressure air.
Prior to any operation, release lubricating oil from the crankcase.
