Injection Pump Unit (Continued)
(Reassembling the fuel injection pump unit)
1. Place the piston of the 4th cylinder at the top dead center in the
compression stroke. Fix the flywheel with the flywheel stopper.
2. Place the injection pump gear (5) back into the gear case
position. Make sure of aligning the align marks of the injection
pump gear (5) and the idle gear 2 (7).
3. Install the injection pump unit to the injection pump gear (5).
NOTE
• When installing the injection pump unit to the injection
pump gear, make sure that the key is fit in the keyway of
injection pump gear.
4. Temporarily tighten the injection pump gear mounting nut by
hand.
5. Fix the injection pump unit and tighten the injection pump gear
mounting nut to the specified torque.
6. Take off the fuel cam shaft lock screws (2) and tighten the flange
screws (1) for plugging.
7. Loose the injection pump unit mounting flange nuts (4) for
aligning the injection timing.
8. Moving the injection pump unit clockwise (viewed from gear case
side), align the injection timing marks (6) on the injection pump
unit and on the gear case.
9. Tighten the injection pump unit mounting flange nut (4) to the
specified torque.
10.Reconnect the lubricating oil pipe (3) and place the injection
pump unit support and the gear cover of the injection pump unit.
11.Remove the flywheel stopper.
12.Check the injection timing. (See page 1-S70.)
13.If the injection timing is not within the specification, repeat 7 to 12
again.
