Camshaft rear oil seal (page 4 of 6)

Refit

1. Clean the oil seal recess.
2. Clean running surface of camshaft.

3. Ensure tool 18G 1716 is clean.
4. Position new oil seal to recess.

CAUTION: Seal must be fitted dry. Ensure that when fitted, ’open’ side of oil seal faces inwards.

5. Drift oil seal into recess using tool 18G 1716; ensure that seal is fully located in recess.
6. Clean timing belt back plate mating faces.
7. Fit back plate to engine, fit bolts and tighten to 8 Nm.
8. Clean tensioner pulley.
9. Fit tensioner pulley to gearbox mounting plate locating dowel, fit Allen bolt but do not tighten.
10. Clean camshaft gear.

CAUTION: If the sintered gear has been subjected to prolonged oil contamination, it must be soaked in a solvent bath and thoroughly washed with solvent before refitment. Because of the porous construction of the sintered material, oil impregnated in the gear will emerge and contaminate a new belt. Cause of contamination must be rectified.

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.
