Perkins 4-Cylinder Series Engines Workshop Service Repair Manual
To check the timing mark of the fuel injection pump
1 Remove the fuel injection pump from the engine, see Operation 11-14.
2 Fit the adaptor PD.67-3 (A) to the drive shaft of the fuel pump and fasten it with the nut of the fuel pump gear. Perkins 4-Cylinder.
3 Connect number 1 outlet (B1) to an atomiser tester. Operate the hand pump until a pressure of not more than 50 atm (735 lbf in2) 52 kgf/cm2 is indicated on the gauge.
4 Rotate the drive shaft of the fuel pump clockwise from the drive end of the pump until the pin in the shaft aligns with number 1 outlet. Loosen the screw (C3) on the timing tool MS.67B and set the timing tool to the correct pump mark angle, see “Static timing – Stanadyne fuel injection pump” on page 24. Tighten the screw.
5 Put the sleeve (C1) for the timing tool in position on the fuel pump. Fit the timing tool to the adaptor on the fuel pump drive shaft. Rotate the shaft backwards and forwards until the fuel pressure prevents movement of the shaft. This is necessary as fuel must pass the delivery valve in the fuel pump before the fuel pressure will prevent movement of the shaft. In this position, the fuel pump is set at the start of injection from number 1 outlet.

Loosen the screw (D4). Slide the pointer forward to the complete width of the flange and tighten the screw. Make a new mark on the flange of the pump through the slot in the pointer.
8 Remove the timing tool, the sleeve and the adaptor.
9 Disconnect the atomiser tester from number 1 high-pressure outlet.
