Introduction
The problem that is identified below does not have a known permanent solution. Until a permanent solution is known, use the solution that is identified below.Problem
Illustration 1 g01955898
Typical exampleThere have been a number of remanufactured 3054C engines that were assembled with a loose 111-3422 Nut (1) for the gear for the injection pump (2). This nut has only received an initial torque of 25 N m (18 lb ft). A second torque of 88 N m (65 lb ft) is required. Without this required torque, the timing of the engine may be affected.The remanufactured part numbers for the engine and serial numbers that have been identified with the loose nut for the fuel injection pump gear are listed in table 1.

54E09028 Solution
The nut that secures the fuel injection pump gear requires a second torque of 88 N m (65 lb ft) prior to engine operation. Refer to Disassembly and Assembly, "Front Cover - Remove and Install" for the correct procedure to remove the front cover. Refer to Disassembly and Assembly, "Fuel Injection Pump - Install" for the correct procedure to tighten the nut.
