Remove Fuel Injection Pumps
Start By:
a. remove fuel injection lines
1. Remove the plug, and move the race until Tool (A) can be installed to hold the rack in the center
position. The rack must be in the center position to remove the fuel injection pumps.
To prevent possible personal injury carefully follow the steps below.

2. 2. Put Tool (B), except for the 8T5287 Wrench, in position on the fuel pump housing as shown.
Lower the handle to center the adjusting screw with the fuel line seat. With the handle down in the
locked position, the adjusting screw must just be in contact with fuel line seat (1). If force is needed
to lower the handle or there is a gap, remove the tooling, and make an adjustment to the screw.
3. Loosen bushing (2) 1/4 of a turn.
4. Put Tool (B) in position on the pump housing with the handle down in the locked position as
shown.
5. Remove bushing (2) from the pump housing.
6. Carefully and slowly lift the handle to release the spring force. Remove the tooling.
7. Install Tool (C) on fuel pump (4) as shown.
8. Remove seal (3) and fuel pump (4) from the fuel pump housing.
9. Remove spacers (5) from the pump housing.
NOTE: There must be a pump installed on either side of the pump to be removed to install Tool (B).
If there is no pump, take a pump already removed, and remove the spring so there will be no spring
force, and install it in the pump housing. See Install Fuel Pump.
NOTE: Spacers (5) are the same thickness for each fuel injection pump so they can be mixed. The
fuel injection pump plungers and barrels are sets and cannot be mixed.

3. 1. Install spacers (5) in the fuel pump housing.
2. Move the rack until Tool (A) can be installed to hold the rack in the center position. The rack
must be in the center position to install the fuel injection pumps.
3. Install a fuel pump without its spring so that Tool (B) can be installed. See Step 5 for correct fuel
pump installation.
4. Install Tool (C) on the bonnet of the fuel pump as shown.
5. Install the fuel pump in the pump housing with the saw cut (slot) (9) in the gear in alignment with
small pin (6) in the lifter assembly and groove (8) in the barrel in alignment with large pin (7) in the
pump housing.

4. 6. Install the seal and bushing (2) on the fuel pump.
7. Put Tool (B) in position on the fuel pump housing as shown.
8. Lower the handle slowly and carefully. If the fuel pump is not installed correctly, the handle will
not go all the way down. Do not try to use force on it. Remove and install the tooling and the fuel
pump again.
9. Make sure the seal is in its correct position, and start to tighten bushing (2). Remove the tooling,
and tighten the bushing to a torque of 260 ± 15 N·m (190 ± 10 lb ft). Back off 180 degrees and
tighten the bushing again to a torque of 260 ± 15 N·m (190 ± 10 lb ft).
Typical Example
10. After each fuel pump has been installed, follow the steps below to check total race travel to
make sure each pump has been installed correctly.
a. Install Tool (D) on the fuel pump housing as shown and zero the dial indicator.
b. Remove Tool (A) from the fuel pump housing.
c. Move rack (10) in and out of the fuel pump housing to measure rack travel. Rack travel is
approximately 9.62 mm (.379 in) in the plus (full fuel) direction and 10.40 mm (.410 in) in the
minus (shutoff) direction. If this measurement is not obtained, center the rack, install Tool (A), and
remove and install the fuel pump again.
NOTE: One tooth off and rack travel is approximately 6.35 to 6.82 mm (.250 to .269 in) in the plus
direction and 7.02 to 7.05 mm (.276 to .278 in) in the minus direction.

5. a. remove fuel injection pumps
NOTICE
Be careful when the injection pumps are disassembled. Do not damage
the surfaces of the plungers, barrels and bonnets. Any scratches will
cause leakage inside the fuel injection pump. The plunger and barrel
for each pump are made as a set. Do not put the plunger of one pump
in the barrel of another pump. If one part has wear, install a complete
