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 valve, which regulates the oil pressure.
- On the flywheel side crankcase half, take partic-
