Adjust speed control lever knob until governor yoke (8) is centered in engine block opening.
The access hole on fuel injection pump has an access hole pointer
match mark Make sure the pointer of the control lever lines up with the
match mark. (Refer to Figure 4-15)
Carefully insert fuel injection pump (6) onto the studs making sure the speed control lever engages into
governor yoke (8).
Secure fuel injection pump onto studs using two nuts (5).
Attach pump viewing access plate (3) and gasket (4) with one hex nut (2).
Torque the hex head securing nuts to 7-9 ft-lb (100-120 cm-kg).
Replace fuel line with hose clamp.
Replace lower fuel tank mounting bracket.
Install fuel tank (refer to para 3-18).
Install fuel injection pipe and bleed air from fuel system (refer to para 3-20).
Fuel injection timing must be precise. if it is too early or
too late, the engine will start hard, provide lowered out-
put, knock and show poor exhaust color. The injection
pressure must be adjusted first. (Refer to para 5-3)
The fuel injection pump is a nonrepairable item and must
be replaced as a complete unit. However, it must be
remembered that the fuel timing is adjustable.
Remove sound enclosure air flow baffle (refer to para 4-10).
Remove fuel injection pipe (refer to para 3-20).
Set speed control lever knob to run position.
Match the T position mark on the flywheel with the V-shaped mark-off line on the cylinder body fin.
Set the decompression lever to start (downward) position.
Turn the flywheel first clockwise, then counterclockwise about 30 degrees from the T mark to make
sure fuel is discharged from the fuel injection pump outlet. Repeat Steps c and d if necessary to inject
Turn the flywheel slowly until fuel just begins to flow from the pump outlet. Note the timing position on
the flywheel when fuel starts to flow.
Repeat 3 or 4 times to make sure the reading is correct.
