How do you Time a John Deere Diesel Injection Pump?

To time a JOHN DEERe diesel injection pump, first ensure the engine is at top dead center (TDC) on the compression stroke of the first cylinder. Remove the inspection plug from the pump and align the timing marks on the pump with those on the engine. Install the pump while ensuring the drive gear engages correctly, and double-check the alignment. Finally, secure the pump and verify the timing by checking the injection timing with a timing light or dial gauge if necessary.
