Disconnect battery cables.
Disconnect accelerator cable or linkage from
outer injection pump control lever.
Remove injection pump timing pointer plug and
gasket from left side of pump mounting adapter.
Rotate engine in normal operating direction until
approximately 90 degrees from top dead center
dot on crankshaft pulley. (The injection pump is
driven at one-half engine speed. Therefore,
each time the injection pump hub mark is
aligned with injection pump timing pointer,
engine should be on number one cylinder
NOTE: If engine gear train was disassembled, verify
that engine is positioned at number one
cylinder compression stroke by:
Removing valve cover.
Observing that number one cylinder intake
and exhaust valve levers are loose.
If number one cylinder valve levers are not
loose, rotate engine one complete revolution
to approximately 90 degrees before top dead
Turn engine slowly in normal direction of rotation
until timing mark on hub is aligned with injection
pump timing pointer (observe through mounting
adapter, Figure 19). If engine is turned past
timing mark, rotate engine counterclockwise at
least 90 degrees to remove gear train backlash.
Rotate engine until timing mark and pump timing
pointer are aligned.
