Cylinder head inspection (page 7 of 9)

66. Check locking pin 18G 1717 is inserted in holes in injection pump gear and gearbox mounting plate and that 4 bolts securing injection pump timing belt camshaft gear to hub are loosened sufficiently for gear to rotate within slots without tipping.
67. Fit injection pump timing belt using fingers only rotating the 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 original belt is to be refitted, ensure direction of rotation is correct. Ensure that camshaft does not rotate and that timing marks are still aligned.

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

CAUTION: Do not exceed specified torque.

70. Remove timing pin 18G 1523 and locking pin 18G 1717.
