Low Speed
1. Loosen the jam nut on the low speed adjustment screw.
2. Run the unit with the throttle solenoid de-energized.
Adjust the screw to the desired speed.
3. Shut the unit off and tighten the jam nut.
Maximum Speed
The maximum speed limit screw is adjusted and sealed at
the factory. It should not need adjustment. If it has been
tampered with, it should be adjusted to give 0.5 mm
(0.02 in.) clearance to the pump control lever when the unit
is in high speed.
Full Load Adjusting Screw
The full load screw is set and sealed at the factory and
should not need adjustment. If the adjustment has been tam-
pered with, the injection pump should be recalibrated by a
diesel injection service.
In an emergency, a rough setting for the screw is approxi-
mately 15.5 mm (0.61 in.) from the tip of the screw to the
face of the nut.
CAUTION: The adjustment of the full load screw
can damage the engine and may void the warranty.
Injection Pump Service
NOTE: The procedure outlined will assume the pump is
being removed and replaced on the engine. If the pump
has not been removed, only the last portion of the proce-
dure is used for timing.
Injection Pump Removal
1. Remove the fuel injection lines. Cover all injection
lines and fuel lines with plastic covers or tape. The
smallest amount of dirt can damage the fuel system.
2. Remove inlet and outlet fuel lines from the transfer
pump. Cap all lines.
3. Remove the high speed linkage.
4. Remove the five mounting bolts that fasten the timing
cover to the pump mount flange.
NOTE: Do not remove the two bolts that fasten the
pump to the pump mount flange.
5. If necessary, remove the two block-to-bracket bolts on
the lower injection pump mounting bracket.
6. Remove the injection pump.
Injection Pump Installation & Timing
1. Remove the rocker arm cover and rotate the engine in
the direction of rotation, clockwise from the front, until
both push rods on the No. 1 cylinder are loose and the
injection timing mark on the flywheel lines up with the
pointer in the bellhousing.
An alternative method is to remove both access covers
from the timing gear cover and rotate the engine in the
direction of rotation until the “O” on the cam gear lines
up with the pointer in the cam gear access hole, and the
injection timing mark lines up with the pointer in the
bellhousing.
