and intake side cam shaft to the crankcase.
Carefully pull upward on the cam shaft to remove
the assembly from the crankcase cavity. A small
rubber oil pump outlet seal* on the outlet of the oil
pump may become dislodged during removal. Do
not lose it. See Figure 8-42.
*NOTE: Most models use the outlet seal with the
internal passage to feed oil to the lower main
bearing. Some models use a solid seal, and
the crankshaft is cross drilled to feed oil to the
lower bearing. If the seal needs to be
replaced, be sure the correct outlet seal is
used.
