Typical example
Note: Do not remove hub nut (4) from the shaft of the fuel injection pump. The hub of the
fuel injection pump is installed in the correct position from the factory in order to ensure
proper timing. If hub nut (4) is removed and the hub is removed, the hub will need to be
accurately installed on the shaft of the fuel injection pump by the use of special equipment.
Refer to your Caterpillar Dealer for more information.
Note: Do not release torx screws (5) (if equipped). If the torx screws are released and the
timing plate is moved, the timing position that is set at the factory will be lost. If the torx
screws are released, the No. 1 cylinder must be set to the top center position on the
compression stroke before the torx screws are tightened.
3. Slowly rotate the crankshaft until hole (6) in the timing gear and hole (7) in the hub are in
alignment with hole (8) in the fuel injection pump body.
Note: The location of Tool (A) for Bosch fuel injection pumps will be located toward the
top of the fuel injection pump. The location of Tool (A) for Delphi (Lucas) and Stanadyne
fuel injection pumps will be located toward the bottom of the fuel injection pump.
4. Install Tool (A) through hole (6) in the timing gear and hole (7) in the hub. Push Tool (A)
into position in hole (8) in the fuel injection pump body. If Tool (A) can be fully seated, the
fuel injection pump timing is correct. No resistance should be felt when the timing pin is
inserted into hole (8) of the fuel injection pump body.
3/4(W)w

Note: Some fuel injection pumps are installed with tamper proof bolts. Tool (B) may be
necessary in order to remove the tamper proof bolts.
5. Remove four bolts (3) that fasten the fuel injection pump gear to the fuel injection pump.
Timing gear (9) should be free from the fuel injection pump shaft.
Typical example
6. Remove three flange nuts (10) and fuel injection pump (11) from the engine.
Typical example
7. Remove O-ring seal (12) from fuel injection pump (11) .
