Camshaft rear oil seal (page 4 of 6)

11. Position injection pump timing belt camshaft gear to camshaft.
12. Apply clean engine oil to threads of new camshaft gear bolt.
13. Fit but do not tighten camshaft gear bolt.

CAUTION: Ensure camshaft does not rotate.

NOTE: Bolt is tightened after timing belt has been tensioned.

14. Ensure that 4 bolts securing injection pump timing belt camshaft gear to hub are loose enough for the gear to rotate in slots without tipping.

15. Check that timing pin 18G 1523 is fully inserted in hole in flywheel and locking pin 18G 1717 is inserted through injection pump drive gear and into hole in mounting plate.
16. Check that camshaft gear timing mark is aligned with mark on back cover.
17. Fit injection pump timing belt using the fingers only, rotating the 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.
