Fuel injection pump timing belt (page 2 of 4)

Refit

1. Clean timing belt gears.

CAUTION: If the camshaft gear has been subjected to prolonged oil contamination, it must be soaked in a solvent bath and thoroughly cleaned and dried before re-use. The cause of oil contamination must be rectified.

2. Leave the 4 bolts securing the injection pump timing belt camshaft gear to hub just loose enough for the gear to rotate within slots without tipping.
3. Fit timing belt using fingers only rotating the injection pump timing belt camshaft gear fully clockwise within the slots, and then anti-clockwise until the belt locates in the gear teeth. Fitting the belt in the other possible position will not allow for correct belt adjustment.

CAUTION: If the original belt is to be refitted , ensure direction of rotation mark is correct.

4. Loosen tensioner pulley Allen bolt.
5. Using a torque wrench fitted to tensioner backplate, apply a clockwise (viewed from rear of engine) torque loading of 6 Nm to timing belt. Maintain loading and tighten tensioner pulley Allen bolt to 44 Nm.

CAUTION: Do not exceed specified torque.

6. Remove injection pump gear locking pin 18G 1717 and timing pin 18G 1523.
