16.1 Preparatory Information
Precautions for operation
The crankcase is a thin-walled casting. Heavy impact should be avoided during the operation to prevent
deformation or breakage.
Before the inspection and measurement, all parts shall be cleaned and blown with high-pressure air.
Before operation, the lubricant in the crankcase should be released.
Function of crankcase:
The crankcase is the force-bearing part of engine. Its main function is to support the crankshaft, clutch, gearbox,
cylinder block and cylinder head, withstand the combustion explosion impact and inertia force of movement of
crankshaft mechanism and form a part of closed (oil and air seal) space.
The crankcase is also equipped with suspension holes, and the engine is connected with the frame and other parts
through the connection with the suspension holes on the motorcycle.
