Completely loosen the belt tension by acting on the tension roller (10).
Remove the timing belt.
Installation
Reinstall the timing belt (new), in the following order:
- intake camshaft pulley;
- exhaust camshaft pulley;
- bypass roller;
- crankshaft pulley;
- install tool 4;
- coolant pump pulley;
- dynamic tensioner roller.
Remove tools 1-4.
Excessive belt tension
Position «A»: Tensioner pulley in loose position.
Position «b»: Tensioner pulley in normal position.
Position «With»: Tensioner pulley in high tension position.
Rotate idler (10) with hex socket wrench (in the zone «e»).
Position pointer «d» pregnant «With».
Tighten the belt to the maximum within the specified interval.
Tighten the tensioner pulley screw to 21 Nm.
Make four revolutions of the crankshaft in the direction of normal rotation.
Attention. Do not allow the crankshaft to turn in the opposite direction.
Check the installation of the gas distribution mechanism by installing pins 1-3, then remove the tools.
Timing Belt Tension Adjustment
Loosen the nut while holding the tensioner roller in place with a hex wrench in the area «e».
Then move the arrow «d» to the adjustment position «b».
Attention. Pointer «d» should not pass through the slot «b». Otherwise, repeat the belt tensioning operation.
Hold tension roller (10) in this position with a hex socket wrench. Tighten the tensioner pulley screw.
Attention. The tensioner pulley should not turn when tightening its fastening. Otherwise, repeat the timing belt tensioning operation.
