In order to allow equitable parts availability to all participating dealers, please limit your initial parts order to not exceed 1% of dealership population. This is an initial order recommendation only, and the ultimate responsibility for ordering the total number of parts needed to satisfy the program lies with the dealer.
ACTION REQUIRED
Replace the failed fuel injection pump. Refer to the engine's Disassembly and Assembly, "Fuel Injection Pump - Remove and Install".
While carrying out "Fuel Injection Pump - Remove", please ensure that the fuel injection pump gear backlash is removed and the fuel injection pump locking bolt is tightened to a torque of 17 N.m (13 lb ft).
Fuel injection pumps that have not been locked correctly will have the claim rejected or debited.
After the new fuel injection pump has been installed, carry out checks for air in the fuel. Refer to the engine's Testing and Adjusting, "Air in Fuel - Test".
To ensure correct priming of the fuel system on first start-up, follow the procedure below.
1. Ensure that all low pressure fuel connections and high pressure fuel lines are installed correctly.
2. Turn the ignition key to the RUN position. Leave the ignition key in the RUN position for three minutes.
3. Crank the engine with the throttle lever in the CLOSED position until the engine starts.
Note: If necessary, loosen the union nuts on the fuel injection lines at the connection with the fuel injector until fuel is evident. Stop cranking the engine. Tighten the union nuts to a torque of 30 N.m (22 lb ft).
4. Start the engine and run the engine at low idle for one minute.
5. Cycle the throttle lever from the low idle position to the high idle position three times. The cycle time for the throttle lever is one second to six seconds for one complete cycle.
6. Check for leaks in the fuel system.
