Timing pin - Stanadyne fuel injection
pumps
1 Disconnect the battery before the fuel injection pump is removed from the engine.
2 Set the engine to TDC with the number 1 cylinder on the compression stroke, see Operation 8-1
3 Remove the gear cover from the cover of the timing case.
4 Insert the timing pin (A1) through the hole (A6) in the fuel pump gear and the slot of the hub (A5). Push the
pin fully into the hole (A4) in the body of the fuel pump. If the pin can be fully inserted then the pump timing is
correct. There should be no resistance when the pin is inserted.
Cautions:
l Use a second spanner to prevent movement of the high-pressure outlet when the union nut (B2) for each
high-pressure pipe is released.
l Ensure that the position of the earth connection (B1) and the electrical supply connection (B5) for the
electrical stop solenoid on top of the governor housing are connected correctly.
5 Remove the high and low pressure pipes. Disconnect the connections for the cold start advance unit (B3),
and the electrical stop solenoid (B1)(B5) from the fuel pump. Disconnect the control rod
Caution: Put some lint-free cloth between the face of the fuel pump gear and the timing case to ensure that
the gear to hub fasteners (A2)(A7) do not fall into the timing case. If this occurs the timing case cover must be
removed.
6 Remove the torx screw (A7) and the three Allen screws (A2). Release the fuel pump gear from the hub of
the fuel injection pump.
7 Remove the nuts (B4) from the flange of the fuel pump and remove the pump. Do not damage the timing
pin when the pump is removed.
