(2) Remove fuel injector from cylinder number 1.
(3) Remove the crankcase breather from the gear
housing cover.
(4) Using Special Tool 7471B rotate the engine
until the timing mark on the fuel pump gear is
aligned with the TDC mark on the gear housing
cover.
(5) Using a 8 in.x 1/4 in. dowel rod inserted into
cylinder number 1, rock the crankshaft back and
forth to verify piston number 1 is at TDC.
(6) With piston number 1 at TDC the timing mark
on the fuel pump gear should be aligned with the
TDC mark on the gear housing cover. If marks do not
line up, remove the gear housing cover.
(7) With cylinder number still at TDC, inspect the
keyway on the crankshaft gear for proper alignment
(12 o'clock position).
(8) If the keyway is not at 12 o'clock position
replace the crankshaft gear assembly.
(9) If the keyway is at 12 o'clock position, verify
timing mark alignment between the camshaft gear,
crankshaft gear and the fuel pump gear, if not
aligned inspect keyway on camshaft gear.
(10) Inspect keyway on camshaft gear for proper
alignment with the key in the camshaft, if alignment
is off replace the camshaft/gear assembly.
(11) If timing marks alignment is off and no dam-
age is found at either the crankshaft or camshaft
gear keyways, realign timing marks as necessary.
