Special requirements
Description
Timing pin - Stanadyne fuel injection
pumps
Caution: The engine must be set to TDC number 1 cylinder, compression stroke before the pump is fitted. If
the crankshaft needs to be rotated, the pump must be fitted temporarily, or the loose gear could damage the
timing case.
1 Fit a new joint (A1) to the timing case. Fit a new "O" ring (A2) to the fuel pump. DB4 fuel pumps are fitted
with a rubber seal that have a square section instead of an round section. When a rubber seal is fitted it is not
necessary to fit a new joint.
2 Lightly lubricate the "O" ring with clean engine lubricating oil and put the pump into position on the timing
case.
3 Put the fuel pump in position on the three studs of the timing case and fit the flange nuts.
4 Tighten the flange nuts of the fuel pump to 19 Nm (14 lbf ft) 1,94 kgf m.
Caution: Do not remove the nut (B3) 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.
5 Put the fuel pump gear onto the hub of the fuel pump. The torx screw (B7) and the three Allen screws (B2)
for the fuel pump gear should be in the centre of the slots to allow for the removal of the backlash. Tighten the
setscrews finger tight.
Note: The fuel pump gear in the timing case will only fit in one position. The gear is fitted with the letters C and
M at the front when in mesh.
6 Insert the timing pin (B1) through the hole (B6) of the fuel pump gear and the slot of the hub (B5) until it can
be pushed fully into the hole (B4) in the body of the fuel pump. 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, see Operation 8-1.
