Oil pressure switch (page 3 of 3)

19. Loosen tensioner pulley Allen bolt₁¹/₂ turn.
20. Loosen tensioner backplate bolt /₂ turn.
21. Push tensioner pulley down to fully OFF position and tighten backplate bolt to 10 Nm.
22. If camshaft timing belt is to be refitted, mark direction of rotation on belt.
23. Remove camshaft timing belt.

CAUTION: Ease timing belt off gears using fingers only. Metal levers may damage the belt and gears. Do not rotate the engine with the timing belt removed and the cylinder head fitted. 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 use a timing belt that has been twisted or bent double as this can damage the reinforcing fibres. Do not use and oil contaminated timing belt.

NOTE: The cause of oil contamination MUST be rectified.

Refit

1. Clean timing belt gears and pulley.

CAUTION: If the sintered gears have been subjected to prolonged oil contamination, they must be soaked in a solvent bath and then thoroughly washed in clean solvent before refitment. Because of the porous construction of sintered material, oil impregnated in the gear will emerge and contaminate a new belt.

2. Clean crankshaft pulley.
3. Check correct alignment of dots on crankshaft with flange on oil pump.
4. Using fingers only, fit timing belt. ensure belt run between the crankshaft gear and the camshaft gears is kept taut during the fitting procedure.

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

5. Check that timing belt is positioned centrally around all gears and tensioner pulley.
6. Fit timing belt lower cover ensuring correct position of rubber seal.
7. Fit bolts securing timing belt lower cover to engine and tighten to 9 Nm .
8. Position drive belt tension adjuster to power steering pump bracket, fit bolts and tighten to 25 Nm.
9. Fit power steering pump tensioner pulley and secure with washer and nut.
