been removed, its weight may topple pump when the
hold down bolts are removed.)
When installing new pump, be sure flywheel is in line
with motor pulley before removing wedges and tightening.
NOTE: When removing discharge tube connector from
old pump, it is recommended that the male
coupling on the discharge tube be loosely
installed in the connection to prevent its
collapse during removal.
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.
