3.5.3. Adjustment of a tension

GENERAL INFORMATION

Prevention

For measurement of a tension of a gear belt it is necessary to use the special Opel tool No. KM-666. In the absence of this tool the tension of a gear belt can be adjusted manually approximately, but after that it is necessary to address as soon as possible on service station for adjustment of the correct tension of a gear belt.


Adjustment without special measuring tool

You make adjustment of a tension of a gear belt on the cold engine.
PERFORMANCE ORDER
1. Remove a casing of a gear belt and, having weakened a bolt of fastening of a pulley of the mechanism of a tension, check that VMT tags on pulleys of the camshaft and a bent shaft were combined with indexes. If necessary tighten a bent shaft that tags were combined.
2. Turn a tension mechanism pulley to a gear belt so that in the center of the longest branch of a belt the belt could be turned on 45 ° hand fingers, putting moderate effort.
3. Turn a bent shaft of the engine clockwise on two whole revolutions and check that VMT tags on pulleys of a bent shaft and camshafts were combined with indexes.
4. Establish an external casing of a gear belt. Check that rubber sealing rings in openings under screws fell into place, then fix a casing by screws.
5. Establish a belt of the drive of the generator and adjust its tension.
6. Establish a belt of the drive of the pump of the amplifier of steering and adjust its tension.
7. Install the air filter.
8. Connect a weight wire to the accumulator.
9. After adjustment of a tension of a gear belt at the first opportunity address on service station for carrying out adjustment with use of special tools.

Adjustment with use of the special Opel KM-666 tool

Rotate a bent shaft evenly and smoothly to exclude jumping of a gear belt on teeths of pulleys. Tighten a bolt of fastening of a pulley of the mechanism of a tension the required moment.
6. Remove the special tool.
7. Turn a bent shaft of the engine clockwise before combination of a tag of the top dead point on a pulley of a bent shaft. At the same time check that tags of the top dead point on pulleys of camshafts were combined with indexes.
8. Establish an external casing of a gear belt. Check that rubber condense telny rings in openings under screws fell into place, then fix a casing by screws.
9. Establish a belt of the drive of the generator and adjust its tension.
10. Establish a belt of the drive of the pump of the amplifier of steering and adjust its tension.
11. Install the air filter.
12. Connect a weight wire to the accumulator.
