3.5.3. Tension adjustment

GENERAL INFORMATION

Prevention

For measurement of a tension of a gear belt it is necessary to use the special Opel No. KM-666 tool. 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 the special measuring tool

Adjustment of a tension of a gear belt make 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 labels on pulleys of a camshaft and a cranked shaft were combined with indexes. If necessary tighten a cranked shaft that labels were combined.
2. Turn a pulley of the mechanism of a tension 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 cranked shaft of the engine clockwise on two complete revolutions and check that VMT labels on pulleys of a cranked 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 became on the places, then fix a casing screws.
5. Establish a belt of a drive of the generator and adjust its tension.
6. Establish a belt of a drive of the pump of the amplifier of a steering and adjust its tension.
7. Establish the air filter.
8. Connect a weight wire to the accumulator.
9. After adjustment of a tension of a gear belt at the first possibility address on service station for carrying out adjustment with use of special tools.

Adjustment with use of the special Opel KM-666 tool

Note the seventh tooth located counter-clockwise from a label of VMT on a pulley of a camshaft, operating final valves.

PERFORMANCE ORDER
1. Adjustment of a tension of a gear belt make on the cold engine.
2. 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 labels on pulleys of a camshaft and a cranked shaft were combined with indexes. If necessary tighten a cranked shaft that labels were combined.
3. According to the instruction establish the special KM-666 tool on an arm of a pulley of the mechanism of a tension.
4. Note the seventh tooth, considering counter-clockwise from VMT label on a pulley of the camshaft operating final valves (see drawing).
5. Turn a cranked shaft of the engine clockwise before combination of noted tooth with the index of the top dead point on a cover of a head of the block of cylinders. Rotate a cranked shaft evenly and smoothly to exclude a pereskakivaniye of a gear belt on teeths of pulleys. Tighten a bolt of fastening of a pulley of the mechanism of a tension the demanded moment.
6. Remove the special tool.
7. Turn a cranked shaft of the engine clockwise before combination of a label of the top dead point on a pulley of a cranked shaft. Thus check, that labels 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 steel screws on the places, then fix a casing screws.
9. Establish a belt of a drive of the generator and adjust its tension.
10. Establish a belt of a drive of the pump of the amplifier of a steering and adjust its tension.
11. Establish the air filter.
12. Connect a weight wire to the accumulator.
