Opel:: Vectra B:: Gear belt

3.2.8. Gear belt

Arrangement of adjusting tags of pulleys of camshafts and bent shaft at installation of the piston of the first cylinder in VMT in a compression step

I – pulleys of camshafts

II – a pulley of a bent shaft

Provision of the index of the mechanism of a tension of a gear belt

I – new gear belt

II – a reusable gear belt

Prevention

Replacement of a gear belt needs to be made on the cold engine.

Removal

PERFORMANCE ORDER

1. Install the piston of the first cylinder in VMT on a compression step.
2. Remove a pulley of a bent shaft.
3. On models of 1,6 l unscrew a bolt of fastening of the lower casing and remove the lower casing of a gear belt.
	4. On models of 1,6 l check that adjusting tags of pulleys of camshafts were combined with the top surface of a head of the block of cylinders, and the adjusting tag of a pulley of a bent shaft was combined with the index (see rice. An arrangement of adjusting tags of pulleys of camshafts and a bent shaft at installation of the piston of the first cylinder in VMT in a compression step).
5. Unscrew two bolts of fastening of the sensor of the camshaft to a head of the block of cylinders and move the sensor aside.
	6. On models 1,8 and 2,0 of l check that adjusting tags of pulleys of camshafts were combined with tags on a cover of a head of the block of cylinders, and the adjusting tag of a pulley of a bent shaft was combined with the index on the case (tags are specified by shooters).
	7. Weaken a bolt of the mechanism of a tension of a gear belt (1). Using a key, turn the tension mechanism lever clockwise against the stop therefore the belt tension will decrease. Then tighten a bolt of fastening of the mechanism of a tension (the turnkey opening is specified by figure 2).
	8. Take off a gear belt from pulleys. Do not turn a bent shaft or camshafts before installation of a gear belt.
9. Check a gear belt for wear, stratification or oiling. If on a gear belt there are oil traces, before installation of a new belt find a source of leak of oil and eliminate it.

Installation

PERFORMANCE ORDER

1. Carefully clear pulleys of a gear belt, a pulley of the mechanism of a tension and an intermediate pulley.
	2. Check that adjusting tags of pulleys (And – a tag of a pulley of a bent shaft) are combined with indexes (In).
3. Establish a gear belt on a pulley of a bent shaft and pulleys of the camshaft so that a forward part of a gear belt was constantly tense. In the last turn establish a gear belt on a pulley of the water pump and a pulley of the mechanism of a tension.
	4. Weaken a bolt of the mechanism of a tension of a gear belt for release of a spring of the mechanism of a tension. Turn the tension mechanism lever counterclockwise until the index of the mechanism of a tension does not reach an emphasis. Tighten a bolt of fastening of the mechanism of a tension.
5. Repeatedly check correctness of combination of adjusting tags of pulleys with indexes.
6. For a bolt of fastening of a pulley of a bent shaft turn a bent shaft on two whole revolutions.
7. Repeatedly check that adjusting tags of pulleys of a gear belt were combined with indexes then weaken a bolt of fastening of the mechanism of a tension of a gear belt.
	8. If the new gear belt is established, it is necessary to adjust the tension mechanism so that the index was combined with a safety lock on a basic plate.
9. If the gear belt is established repeatedly, it is necessary to adjust the tension mechanism so that the index was located on 4 mm from a safety lock on a basic plate to the left (see rice. Provision of the index of the mechanism of a tension of a gear belt).
10. Establish a casing of a gear belt and a pulley of a bent shaft. On model of 1,6 l it is necessary to install the camshaft sensor before installation of a casing of a gear belt.
