-- Remove lower bolts from lower section of toothed belt guard -arrows-.
-- Identify TDC position -arrow-.
-- Remove both upper bolts from toothed belt guard -arrows- and remove guard downward from engine.
-- Loosen the lower bolts -3- and remove the engine support downward and out.
-- Mark rotational direction of toothed belt.
-- Loosen tensioning roller and remove toothed belt.
-- Then, turn the crankshaft back slightly.
Installing
- For the correct tightening specifications, refer to TOOTHED BELT DRIVE, WITHOUT DIVIDED TOOTHED BELT GUARD OVERVIEW .
When turning camshaft, crankshaft must not be at TDC. Valves and/or pistons may be damaged.
The engine must be no more than warm to touch.
-- Place the toothed belt onto the crankshaft sprocket (observe direction of rotation).
-- Secure the lower toothed belt guard with the two lower bolts.
-- Install vibration damper with new bolts.
-- Position camshaft and crankshaft on TDC marking.
-- Route toothed belt in the sequence: Tensioning roller, camshaft gear, coolant pump and last over the relay pulley -arrow-.
Be sure tensioning roller is properly seated in cylinder head.
-- Tension toothed belt. Do this by turning the hex key at the eccentric toward the right (in direction of -arrow-) until the notch is positioned above the tab.
-- Release tension on toothed belt again.
-- Now tension toothed belt until notch and tab align.
-- Tighten mounting nut.
-- Turn the crankshaft 2 revolutions further in direction of engine rotation until the engine is positioned at TDC again. For this, it is necessary that the last 45° (1 /8 rotation) is turned without interruption.
-- Check tension of toothed belt again. Specified value: Tab and notch align.
-- Check valve timing. The markings must align -arrows-.
If the markings do not match:
-- Repeat valve timing adjustment.
If the markings match:
-- Bring engine bracket into installation position.
-- Install toothed belt guard from below -arrows-.
-- Install vibration damper/belt pulley with new bolts.
-- Check the valve timing again: The markings must align -arrows-.
-- Tighten both toothed belt guard upper bolts -arrows-.
Note different length of bolts. Bolt -3- is approximately 25 mm shorter than bolts -1 and 2-.
-- Insert the lower bolt -3- into the engine support.
-- Install the engine support from below onto the cylinder block and hand-tighten the bolt.
-- Lift the engine with the 10-222A so far that both upper bolts -1 and 2- can be screwed in.
-- Tighten all bolts.
-- Lower engine to installation position.
-- Install subframe mount for engine completely.
-- Fasten engine assembly mount to engine support -arrows-, bringing the contact surfaces into contact using the 10-222A.
-- Adjust the engine mounts. Refer to SUBFRAME MOUNT, ADJUSTING .
-- Connect fuel hoses to connections. Make sure connector couplings are securely fastened.
-- Install air guide pipes and connector. Refer to HOSE CONNECTIONS WITH CONNECTOR COUPLINGS, ASSEMBLING .
-- Install coolant expansion tank.
-- Install noise insulation.
-- Install the engine cover.
-- Install vibration damper. Refer to VIBRATION DAMPER .
-- Install the ribbed belt. Refer to RIBBED BELT .
