To verify
that
the injection pump is
timed
correctly, first check
the alignment marks on the pump flange and gear housing.
Note:
The alignment mark is unique to each engine.
The pump has a provision for locking the pump shaft at a
position corresponding to top-dead-center for Cylinder
Number 1.
New and reconditioned pumps should be received
with
the
shafts
locked in this position.
Caution: If the
timing
pin is Incorrectly located on the
gear housing, the
timing
procedure
will
not ensure
that
the pump is
timed
correctly.
After
precisely locating TDC for Cylinder Number 1, the factory
positions the
timing
pin
assembly
to the gear housing using the
timing
pin and the hole in the camshaft gear, if the gear
housing or
timing
pin assembly are removed, the same
precision
is required to relocate it.
