Unplug the injection actuation pressure controlvalve.
Crank the engine and note the injection actuationpressure.
Remove the allen head plug.
Turn the load sensing screw in approximately twoturns.
Crank the engine and note the injection actuationpressure.
Connect the injection actuation pressure controlvalve when the procedure is completed. If the injector actuation pressureincreases after the load sensing screw is turned, installing the properone piece compensator plug should correct the condition. If the pressuredoesn't increase, the pump requires rebuilding or replacement.
Follow the procedure in the Reference publicationfor installing the appropriate length compensator plug from the 1618627Plug Kit.
