3 Insert the timing pin (A1) through the hole (A5) in
the fuel pump gear and the slot of the hub (A4). Push
the pin fully into the hole (A3) 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.
Note: The position for the timing pin for Lucas and
Stanadyne fuel injection pumps is (A1). The position
for the timing pin for Bosch EPVE fuel injection pumps
is (B1).
4 Remove the timing pin.
5 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 17-1 or operation 17-2.
If the engine is set correctly at TDC on the number 1
cylinder compression stroke, but the pin does not fit
into the hole, the fuel pump must be removed and set
by a specialist.
6 Fit the gear cover to the cover of the timing case.
For gear driven coolant pumps: Fit the coolant pump,
see operation 21-2.
