3.7. Check of a state and replacement of a belt of the drive of auxiliary units
Every year
Check
Driving, or as it is called sometimes, the V-shaped belt is located in a forward part of the power unit and is applied to the drive of such auxiliary units as the generator, the steering pump and the К/В compressor. Eventually the belt wears out and has to look round regularly according to the schedule of routine maintenance of the car in order to avoid serious engine failures which correction of consequences can become the owner of the car in kopek. On the models completed with K/V or GUR the strengthened (ridge) belt is established.
|
- Kill the engine, open a cowl and find a driving belt in a forward part of the power unit. Highlighting itself a small lamp, fingers feel a belt on all its length, checking for existence of cracks and stratifications. Inadmissibly also presence on a belt of attritions, zapolirovanny to gloss of sites and other obvious defects Examine a belt on both sides for what overwind them. The worn-out or damaged belt is subject to replacement.
Typical examples of wear of V-shaped driving belts
- Check a belt tension.

The tension of the strengthened belt has to be regulated only after its removal. An inspection of a tension within carrying out maintenance is not carried out. |
Replacement
The V-shaped belt of models with l OHC 1.2 and 1.4 engines without GUR or K/V and diesel engines
|
- On petrol models remove the air cleaner with inlet air ducts.
- Also install the car with the diesel engine to a poddomkratta on props.
- On petrol engines to 08.1994 g of the issue weaken a bolt of fastening of a tension level and incline the generator towards the engine Thus the tension of a driving belt is weakened. If necessary weaken the lower bolt of an arm of the generator.
Bolt of fastening of a tension level
-
On petrol engines from 09.1994 g of the issue turn out a bolt (1) of an arm of the generator / inlet the pipeline. Give bolts (2) fastenings of a tension level of the generator. Give a bolt of fastening of the lower support of the generator (3). Give a tension bolt (4) of a driving belt.
Belt tension components
- Take off a driving belt.
- Establish a new driving belt.
- On petrol engines to 08.1994 g of the issue wring out the generator mount from the engine. Fix a tension level. On engines from 09.1994 g of the issue tighten a tension bolt so that to reach the correct tension of a belt. Tighten bolts of fastening of an arm of the generator.
- On the diesel engine wring out the generator a tetrahedral key from the engine and fix a tension level.
- Check a belt tension a hand thumb. In a point where check of a tension is made by the special device, the belt has to have a deflection of 5 mm. However at the next carrying out maintenance it is necessary to check a belt tension for HUNDRED since at incorrect adjustment the belt can slip.
|
The correct tension of a maple belt has significant effect on the term of its service. It is recommended to use the special KM-128-A tool to check of a tension of a belt. Without the specified tool it is correct to adjust and check a tension of a belt it is impossible since the new driving belt has a big preliminary tension. |
- As a surface for check whenever possible it is necessary to choose the middle between two pulleys. On the diesel engine the tension of a belt should be checked from below.
- Install the device for check on a driving belt so that the belt passed through guides.
- Press the lever so that the microswitch pin (in the bottom of the device) concerned a driving belt. At a contact the sound signal is distributed.
Check of a tension of a belt by means of the special device
- Consider value on a scale of the device and increase it on 100. The received value corresponds to force on belt tyazheniye in newtons.
- The tension of a belt has to make 250 ÷ 300 N and there should not be less than 250 N at all.
|
The new driving belt at installation has to be tense with effort 450 N. If the tension of a belt goes beyond the specified limits, it is necessary to pull a belt.
|
- On petrol engines tighten bolts of fastening of a tension level and the generator with effort of 25 Nanometers. Install the air cleaner with inlet air ducts.
- On the diesel engine tighten bolts of fastening of a tension level with effort of 25 Nanometers and an arm of the generator with effort of 50 Nanometers. Lower the car on the earth.

L OHC 1.2 and 1.4 engines with l GUR and DOHC 1.4 and 1.6
|
- Remove the air cleaner with inlet air ducts (see the Head of the Power supply system, release and decrease in toxicity of the fulfilled gases).
- If the driving belt is recognized suitable for further use, mark with paint or a marker the original direction of its movement. Try to remember an order of laying of a belt around pulleys.
- On the DOHC engine without GUR weaken a belt tension for what develop a natyazhitel counterclockwise for the central bolt.
Weakening of a tension of a belt on the DOHC engine without GUR
-
On the OHC engine with GUR turn a tension roller a cap key clockwise so that openings in the holder coincided and a tension roller record in this situation a tension roller the corresponding core or a hairpin and take off a belt.
Fixing of a tension roller
- Put on a belt pulleys. If earlier used belt is established, pay attention to the direction of its movement.
- On DOHC engines pull a roller a key.
-
On OHC engines slightly turn a tension roller to the right, take out a hairpin from lock openings and slowly unload a belt.
- Release a tension roller, at the same time the necessary tension automatically is established.
- Check correctness of laying of a belt on pulleys. The belt should not act sideways pulleys.
- Install the air cleaner with inlet air ducts (see the Head of the Power supply system, release and decrease in toxicity of the fulfilled gases).

L engines 1.2, 1.4 and 1.6 with GUR and K/V
|
- Disconnect a negative wire from the battery.
- Remove the air cleaner with air ducts and the MAF sensor (the engine of 1.6 l) (see the Head of the Power supply system, release and decrease in toxicity of the fulfilled gases).
- Raise the engine by means of OPEL KM-263-B adaptation.
|
In the absence of the specified adaptation put on wooden laying on wings the corresponding pipe, pass a chain through engine eyes, connect it to a pipe and pull a chain. |
- Turn a tension roller a cap key in the direction of an hour hand so that openings of the holder and a tension roller (A) B this situation coincided record a tension roller the corresponding hook (C).
