5. Record the injection angle marked on the side
of the new injection pump.
6. Calculate the injection angle difference by
subtracting the injection angle of the old
injection pump from the injection angle of the
new injection pump.
7. Install the new injection pump on the gear
case and position it so the index mark on the
injection pump is aligned with the mark equal
to the injection angle difference on the
injection angle sticker (see the following
examples). Tighten the injection pump
mounting nuts when the index mark is aligned
as necessary with the injection angle sticker.
8. Install the injection pump gear, lock washer,
and nut. Torque the nut to 58 to 65 ft-lb (78 to
88 N•m).
NOTE: If the timing gear cover was removed to
remove the injection pump gear, make sure the
timing marks on the timing gears are aligned as
shown below. It helps to install the idler gear last
when aligning the timing marks.
NOTE: The oil pump is located in the timing
gear cover on TK486V engines. The inner rotor
of the oil pump fits around the crankshaft gear.
Make sure that the flat sides of the inner rotor
are aligned with the flat sides on the crankshaft
gear when installing the timing gear cover.
