Fuel Injection Pump
• On TNV94 - 106 model engines, the idler gear
is visible. Make a reference mark
(Figure 7-15, (1)) across both the fuel injection
pump drive gear and the idler gear.

18. Do not loosen or remove the four bolts
(Figure 7-16, (3)) retaining the pump drive gear
to the hub. Only remove the single drive gear
nut (Figure 7-16, (1)) and washer
(Figure 7-16, (2)), leaving the hub attached to
the gear.

19. Hold the gear train using a large socket wrench
on the crankshaft pulley nut. Loosen the fuel
injection pump drive gear retaining nut
(Figure 7-16, (1)) and turn it out to the end of
the fuel injection pump shaft.
20. Remove the pump drive gear and hub as an
assembly using an appropriate two-bolt gear
puller (Figure 7-17).

CAUTION
Do not loosen or remove the four bolts
retaining the fuel injection pump drive
gear to the fuel injection pump hub. Do
not disassemble the fuel injection pump
drive gear from the hub. Correct fuel
injection timing will be very difficult or
impossible to achieve.
