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, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat products. Dispose of all fluids according to local regulations and mandates. |
Note: The removal procedure is similar for the two cylinder, the three cylinder and the four cylinder engines. The illustrations show the four cylinder engine.
- Remove the setscrews (4) and the nuts (2) that fasten the fuel injection pump to the cylinder block.
Note: Ensure that the fuel rack control (5) has been moved away from the recess of the stop solenoid. If this is not done damage may occur.
- Carefully raise the fuel injection pump (1) from the cylinder block and remove the clip (7) that connects the link (6) to the fuel rack control (5).
- Remove the fuel injection pump (1) from the cylinder block.
- Remove the shims (3) from the mounting face of the cylinder block.
Note: Record the thickness of each shim and the number of shims for reassembly. The fuel injection timing is determined by the thickness of the shim pack that is between the fuel injection pump and the mounting face on the cylinder block. For more information on the fuel injection pump, refer to Specifications, "Fuel Injection Pump".
