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
If the engine is stored for 6 months or more, the fuel injection pump linkage needs to be lubricated.
Solution
Follow the procedure in this article to lubricate the fuel injection pump linkage.
- Remove the fuel shutoff solenoid. Refer to Disassembly and Assembly, "Fuel Shutoff Solenoid - Remove and Install" for the correct procedure.
- Spray the fuel control rack with a suitable lubricant spray.
- Use a suitable magnet to operate the fuel control rack. The operation of the fuel control rack will disperse the lubricant.
Note: If the fuel control rack does not move freely, then the fuel injection pump should be replaced. Refer to Disassembly and Assembly, "Fuel Injection Pump - Remove and Install" for the correct procedure.
- Install the fuel shutoff solenoid. Refer to Disassembly and Assembly, "Fuel Shutoff Solenoid - Remove and Install" for the correct procedure.
- Record the repair in the Service Information Management System (SIMSi), including the engine/machine serial number and the date of the repair.
