17. Fit injection pump timing belt using the 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 original belt is to be refitted, ensure direction of rotation is correct.

18. Check that camshaft gear timing mark is still aligned with mark on back cover.

19. Loosen tensioner pulley Allen bolt.
20. Using a torque wrench fitted to tensioner backplate, apply a clockwise (as 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.

21. Remove locking pin 18G 1717 and timing pin 18G 1523.
22. Rotate crankshaft 2 turns clockwise and fit timing pin 18G 1523.

CAUTION: Ensure timing pin is fully inserted in hole in flywheel and that camshaft gear timing mark is aligned with mark on back cover. Do not use camshaft gears, gear bolt or timing belt to rotate crankshaft.

23. Insert locking pin 18G 1717 through hole in injection pump drive gear and into hole in mounting plate.

NOTE: Locking pin may be a tight fit at this stage.

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