D2-55C and D2-75A:
1. Open the priming screw (1) on the fuel filter. Avoid
fuel spillage. Use i. e. rags on the priming point.
2. Pump fuel up with the hand pump (2) until fuel
without air bubbles can be seen. Continue pumping
and tighten the priming screw at the same time.
The pump’s inlet pipe contains a strainer (3) which
normally does not need to be cleaned since the en-
gine has a fuel pre-filter. If a pre-filter is not fitted,
poor feed flow can be due to a blocked strainer.
Note. If either of the two O-rings (4) are damaged,
they must be replaced.
3. Normally, additional priming is not required. Start
the engine and check that no leakage occurs.
4. If the engine does not start after a short attempt,
loosen the pressure pipes at the injectors a few
turns. Hold the injection pump actuator arm in it’s
max.position and crank the engine with the starter
motor until fuel leaks from the pressure pipes.
Tighten the pressure pipe nuts. Tightening torque,
please refer to the “Technical Data” chapter.
The glow plugs are activated at the same time as the
starter motor. You can save the batteries if the starter
motor is only used for short periods when priming.
