NOTE: The procedure outlined will assume the pump is being removed and replaced on the engine. If the pump has not been
removed, only the last portion of the procedure is used for timing.
Injection Pump Removal
1. Remove the fuel injection lines. Cover all injection lines and fuel lines with plastic covers or tape. The smallest amount of
dirt can damage the fuel system.
2. Remove the oil line that goes from the cylinder block to the injection pump and the timing gear cover.
3. Remove the fuel transfer pump from the timing gear cover.
4. Remove the front crankshaft bolt.
5. Remove the crankshaft pulley by using a suitable puller.
6. Remove the timing gear cover and sound shield.
7. Remove the injection pump gear nut and lock washer.
8. Remove the injection pump gear by using a suitable puller.
9. Note the position index marks on the edge of the injection pump.
10. Remove the injection pump from the timing gear housing.
Injection Pump Installation
1. Install the injection pump, align the index marks and tighten the mounting nuts.
2. Place the engine at top dead center of the compression stroke for the number one cylinder. This positions the camshaft gear
and the crankshaft gear as shown in the “Align Timing Marks” illustration.
