Information:

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.
