Problem
Some remanufactured fuel injection pumps have been built with the control solenoid in the wrong position. If the solenoid is in the wrong position, the wiring harness may be impossible to connect to the solenoid due to interference of other components.The affected fuel pump part numbers are:
10R-7659 Unit Injection Hydraulic Pump and Mounting Gp
10R-7660 Unit Injection Hydraulic Pump and Mounting Gp
10R-7661 Unit Injection Hydraulic Pump and Mounting Gp
10R-7662 Fuel Pump Gp
20R-3815 Fuel Injection Pump GpSolution

(X) Pump center line
(Z) Acceptable solenoid connector orientation (15 degrees to 45 degrees from pump center line)Check the fuel injection pump solenoid position before attempting to install the pump. Refer to Illustration 1 and Illustration 2. If the orientation of the connector on the solenoid is not within the acceptable range, return the faulty pump and replace the pump with the same part number.Note: Do not attempt to disassemble the fuel injection pump to reposition the solenoid.
