Injection Pump Timing

Timing of Injection Pump (Pump Mounted on Engine)
The adjustment position for start of injection varies on
each pump (manufacturing tolerances). The adjustment
position is given by measurement "X.XX" in one of three
places on the pump (Fig. 51):
a. Tag on pump lever.
b. Bar code label
c. Inspection cap
NOTE: "PMH" = "TDC"
in French
1. Remove the cover attachment nut, cover clips and
timing belt covers.
2. Slowly turn the crankshaft in the operating direction
(clockwise as viewed from the timing belt end) until the
TDC Lock Pin tool (TOR 70153N) goes into the hole in
the flywheel (Fig. 52).
3. Verify that the camshaft and injection pump gears are
properly timed:
A. Lock the camshaft gear (Fig. 53, Item 6) in position
with a M8 x 125 x 40 bolt. Tighten finger tight.
B. Lock the injection pump gear (Item 7) in position
with two M8 x 125 x 35 bolts. Tighten finger tight.
NOTE: If the locking bolts cannot be installed be­
cause the holes in the gears and engine block do not
align, remove the TDC Lock Pin tool and rotate the
engine (clockwise) one revolution. Install the TDC
Lock Pin, then install the bolts as instructed.
IMPORTANT: To prevent damage to the face of the
injector pump housing and future timing problems,
the camshaft gear and injection pump gear locking
bolts must be tightened ONLY FINGER TIGHT.
4. Remove the three locking bolts (Fig. 53).
5. Remove the TDC Lock Pin tool TOR 70153N, then
turn the crankshaft 1/4 to 1/3 turn in the opposite direc­
tion of running (counterclockwise as viewed from the
timing belt end).
