NOTICE
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.

6. 1. Remove fuel injection pump drive gear access cover (1) from front housing (2).
Note: The cover is secured with adhesive sealant. Use a scraper to separate the cover from
the gear case.
Illustration 2 g03349227
Note: After marking the position of the fuel injection pump drive gear (3) , do not
rotate the engine crankshaft. Rotating the crankshaft will cause the fuel injection
pump to become misaligned.
2. Place a mark on the fuel injection pump drive gear (3) and the idler gear for installation
purposes. Loosen center nut (4) and back out to the end of the fuel injection pump shaft. DO
NOT loosen the four bolts (5) that hold the fuel injection pump gear to the hub.
Illustration 3 g03384642
Note: Do not loosen or remove the four bolts (5) retaining the fuel injection pump
drive gear (3) to the fuel injection pump hub (3A). Do not disassemble the fuel
injection pump drive gear from the hub. Correct fuel injection timing will be difficult
or next to impossible to achieve.
