8
To check the timing of pin-timed fuel injection pumps
Special requirements
Description
Timing pins for Delphi and Stanadyne
fuel injection pumps
Caution: Do not remove the nut (A2) from the shaft of the fuel injection pump. The fuel pump hub is fitted to
the shaft in the factory to ensure that the fuel pump is in the correct position for timing. If the hub is removed,
the hub will need to be accurately fitted to the pump by use of special equipment available to Perkins
distributors.
1 Remove the cover for the fuel injection pump gear.
2 Set the piston of number 1 cylinder to TDC on the compression stroke, see Operation 8-1.
3 Insert the timing pin (A1) through the slot (A3) in the fuel pump gear and the hole in the hub (B1). Push the
pin fully into the recess (B2) 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.
4 If the timing pin cannot be pushed into the pump body, check that the engine is correctly set at TDC on the
number 1 cylinder compression stroke, see Operation 8-1.
5 If the engine is set correctly at TDC but the pin does not fit into the hole, the fuel pump must be removed
and set by a specialist.
6 If the engine is correctly set, remove the timing pin and fit the gear cover of the fuel injection pump back onto
the timing case.
Caution: Remove the pin from the flywheel and the backplate.
