Camshaft timing belt (page 3 of 5)

22. Remove upper bolt securing tensioner to engine block.
23. Loosen lower bolt and allow tensioner to swing away from pulley assembly. Remove bolt and collect tensioner.
24. If timing belt is to be refitted, mark belt direction of rotation.
25. Remove timing belt.

CAUTION: Ease timing belt off gears using fingers only; levers may damage the belt and gears.

CAUTION: DO NOT turn crankshaft with timing belt removed and cylinder heads fitted.

CAUTION: Although the camshaft timing belt has a service life of 96,000 miles, 160,000 km, an existing belt should only be refitted if it has completed less than 48,000 miles, 80,000 km. • DO NOT use a timing belt which has been twisted or bent double because reinforcing fibres may be fractured. Timing belts must be stored and handled with care. Always store a timing belt on its edge with a bend radius greater than 50 mm. • DO NOT not use an oil contaminated timing belt. The cause of oil contamination MUST be rectified.

Refit

1. Remove both exhaust camshaft RH oil seals.

2. Fit tools 18G 1747-2 to both front timing gears.

CAUTION: Tools must be fitted when loosening or tightening gear retaining bolts, otherwise damage to camshafts may occur.

3. Remove bolts retaining front timing gears and discard.
4. Remove tools 18G 1747-2.
5. Clean timing gears, hubs and pulleys.
6. Position timing belt to gears.

CAUTION: If original belt is to be refitted, ensure direction of rotation mark is facing correct way.
