Refit - Engines fitted with automatic timing belt tensioner

1. Clean crankshaft pulley, timing belt gears, coolant pump drive gear and tensioner 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 refitting. Because of the porous construction of sintered material, oil impregnated in the gears will emerge and contaminate the belt.

2. Check correct alignment of camshaft timing marks for 90° BTDC and that tool 18G 1570 is locking camshaft gears.

3. Ensure dots on crankshaft gear are aligned with flange on oil pump and that tool is locking flywheel.

4. Fit timing belt tensioner ensuring that index wire is positioned over pillar bolt and that tensioner lever is at 9 o’clock position.
5. Fit a new tensioner Patchlok bolt and tighten bolt until it is just possible to move tensioner lever.
6. Using the fingers only, fit the timing belt over crankshaft timing gear, then over camshaft gears, coolant pump drive gear and tensioner pulley ensuring that the belt run is kept taut between the crankshaft timing gear and exhaust camshaft gear.

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

7. Check that timing belt is positioned centrally around all gears and tensioner pulley.
8. Fit timing belt lower front cover. See this section.

NOTE: Do not fit timing belt upper front cover at this stage.

9. Raise engine on jack, fit RH engine mounting bolts and tighten to 155 Nm.
10. Remove jack.
11. Remove camshaft gear locking tool 18G 1570.
