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.
4. Do not remove the fuel injection pump drive
gear unless absolutely necessary to avoid
damage to the gear or pump. Do not loosen or
remove the four bolts (Figure 6-92, (3))
retaining the pump drive gear to the hub. Only
remove the nut (Figure 6-92, (1)) and washer
(Figure 6-92, (2)), leaving the hub attached to
the gear. Remove the pump drive gear and hub
as an assembly using a gear puller.
