2. Using 29mm socket (1–1/8 inch) socket rotate
crankshaft to top dead centre (TDC) with number
1 cylinder firing. This indicated by the ‘V‘ cut into
the notch of the sensor wheel (Electronically
governed Pump) which should align with the
sensor. Mechanically governed engines will
indicate TDC with an ‘O‘ on the pulley in line with
the pin on the block. (Refer to Fuel System
Chapter).

pump drive flange aligns with the pump timing
plate.
