Kawasaki Ninja Service Manual: Crankcase Assembly

Kawasaki Ninja Service Manual / Crankshaft/Transmission / Crankcase / Crankcase Assembly

NOTICE

The upper and lower crankcase halves are machined at the factory in the assembled state, so the crankcase halves must be replaced as a set.

With a high flash-point solvent, clean off the mating surfaces of the crankcase halves and wipe dry

WARNING

Gasoline and low flash-point solvents can be flammable and/or explosive and cause severe burns. Clean the crankcase in a well-ventilated area, and take care that there are no sparks or flame anywhere near the working area; this includes any appliance with a pilot light. Do not use gasoline or a low flash-point solvent to clean the crankcase.

Using compressed air, blow out the oil passages in the crankcase halves.
Install the balancer (see Balancer Installation).
