( 1 ) Tool (A) is required in order to remove Bosch fuel injection pumps.
( 2 ) Tool (A) is required in order to remove Delphi (Lucas) and Stanadyne fuel injection pumps.Start By:
Remove the water pump. Refer to Disassembly and Assembly, "Water Pump - Remove".
Remove the fuel injection lines. Refer to Disassembly and Assembly, "Fuel Injection Lines - Remove and Install".
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Caterpillar Tools and Shop Products Guide" for tools and supplies suitable to collect and contain fluids on Caterpillar products.Dispose of all fluids according to local regulations and mandates.
Ensure that the No. 1 cylinder is at the top center position on the compression stroke. Refer to the Testing and Adjusting, "Fuel System" topic for additional information.

Typical exampleNote: 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.
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.
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.Note: Some fuel injection pumps are installed with tamper proof bolts. Tool (B) may be necessary in order to remove the tamper proof bolts.
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.

Illustration 4 g00808386
Typical example
Remove O-ring seal (12) from fuel injection pump (11) .
