Lower Crankcase – Installation
Make sure the motorcycle is stabilised and adequately supported.
A correctly supported motorcycle will help prevent it from falling.
An unstable motorcycle may fall, causing injury to the operator or damage to the
motorcycle.
Perform the following operations:
• Check, measure and, if necessary, select new crankshaft main bearing shells (see
Crankshaft Main Bearing/Journal Checking, Measuring and Bearing
Selection)
Make sure the three piston oil spray jets are installed. If the piston cooling jets are
omitted, oil pressure will be reduced. Running the engine with low oil pressure will
cause severe engine damage.
1. If removed, refit the three oil spray jets and tighten their fixings to 4 Nm.
2. Use high flash-point solvent to clean the crankcase mating faces. Wipe the surfaces
clean with a lint-free cloth.
3. Make sure that the transmission is in neutral.
1. Detent wheel (in
neutral position)
2. Detent arm
