Camshaft rear oil seal (page 2 of 5)

8. Loosen, but do not remove 4 bolts securing FIP drive belt gear to hub.
9. Fit locking pin 18G 1717 through injection pump drive gear and into hole in adapter plate.

CAUTION: Locking pin must be a sliding fit, if pin is tight, rotate pump drive gear slightly using a socket on pump drive gear nut until pin can be inserted correctly.

10. Check that timing marks on camshaft gear and back cover are still aligned.

CAUTION: If drive belt is to be refitted, mark direction of rotation on belt.

11. Loosen Allen bolt securing tensioner pulley, move tensioner away from belt and tighten Allen bolt.
12. Remove FIP timing belt.

CAUTION: Do not rotate camshaft or FIP with timing belt removed. Ease belt from gears using fingers only. Store a belt on its edge with a radius greater than 50 mm. DO NOT use a belt which has been twisted or bent double as this can fracture reinforcing fibres. Do not use an oil contaminated belt. Although the belt has a service life of 84,000 miles, (135,000 km) an existing belt should only be refitted if it has completed less than 42,000 miles, (65,000 km).

13. Remove bolt securing FIP belt drive gear.
14. Remove FIP belt drive gear.

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

CAUTION: If FIP belt shows any sign of oil contamination, renew belt.

15. Remove Allen bolt securing FIP drive belt tensioner and remove tensioner.
