Fig, 4. Crankcase and Oil Pump.
The oil pump is factory ground as an assembly, and
partial replacement is not possible. In the event that the
pump, or crank bearing which is part of the pump, is
deemed faulty, it should be replaced as a unit. The
assembly is held by four bolts (see Fig. 4, front view).
The replacement does not include an oil gauge. If needed,
it must be ordered separately. After reinstallation, the
oil pressure must be adjusted.
