Inspecting the crankcase halves

- Before proceeding to check the crankcase

halves, thoroughly clean all surfaces and oil ducts.

- On the transmission-side crankcase half, take

particular care when handling the oil pump com-

partment and the oil ducts, the by-pass duct, the

main bushings and the cooling jet on the trans-

mission side (see diagram).

- Take particular care, also, that there are no signs

wear in the oil by-pass valve housing (see Chapter

Lubrication), as this could prevent a good seal in

the piston, which regulates the oil pressure.

- On the flywheel side crankcase half, take partic-

ular care cleaning the oil ducts for the main bush-

ings, the oil duct for the jet that lubricates the

cylinder head and the oil drainage duct at the fly-

wheel side oil seal.
