Remove fuel injection linesNote: Refer to Specifications, ""Engine Design"" for non-specified engine torques.
Illustration 1 g03351476
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.
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.
Illustration 4 g03349237
Install Tooling (A) onto the end of the fuel injection pump shaft nut (4). Loosen the pump drive gear (3) from the shaft, remove Tooling (A) and remove nut and washer (4) .Note: Fuel injection pump drive gear (3) can be removed from the gear case, however, would be best to let the gear remain in the gear housing.
Illustration 5 g03349431
Locate and highlight the timing mark (9) on the base of fuel injection pump (6) for installation purposes. Make a corresponding mark on the gear case. Unplug the stop solenoid harness assembly.

Position fuel injection pump (6) into the housing and the pump drive gear. Install nuts (8). Line up timing marks (9) if the old fuel injection pump is being reused. If new fuel injection pump is being installed, refer to Testing and Adjusting, "Fuel Injection Timing - Check/Adjust" for the correct fuel injection timing procedures. Install lube oil line (7). Tighten nut (8) to a torque of 23 to 28 N m (204 to 248 lb in).
Illustration 7 g03349475
Make sure that fuel injection pump drive gear (3) is aligned with the idler gear using the reference marks made earlier. Install the washer and nut (4). Tighten nut (4) to a torque of 59 to 69 N m (44 to 51 lb ft) while holding the crankshaft pulley bolt with a socket wrench to prevent the crankshaft from turning.
