2.2.4. Poliklinova belt

Removal

PERFORMANCE ORDER
1. Weaken bolts of fastening of a pulley of the water pump.
2. Weaken nuts of support of the generator.
3. Weaken a bolt of fastening of the generator and take off poliklinovy a belt.
4. Turn out bolts of fastening of a pulley of the water pump.

Inhaling moment:
Hinged bolt (A) of fastening of the generator: 20–25 N • Bolte (V) m of fastening of the generator: 15–22 N • Bolte's m of fastening of an arm of the generator: 20–28 N • m

Check

Check the following elements and with defects replace them.

PERFORMANCE ORDER
1. Check a surface of a poliklinovy belt for absence of damage and cracks.
2. Check a surface of a poliklinovy belt for lack of oil and lubricant.
3. Check a surface of a poliklinovy belt for lack of uneven wear.
4. Check a pulley surface for lack of cracks or damages.

Installation

PERFORMANCE ORDER
1. Establish a pulley of the pump and fix it by bolts.
2. Establish a pulley of the pump and fix it by bolts.

Check and adjustment of a tension

PERFORMANCE ORDER
1. Check a condition of a poliklinovy belt and its arrangement on pulleys.

Prevention

Check correctness of an arrangement of edges of a poliklinovy belt in flutes of pulleys.
If during the work poliklinovy the belt publishes extraneous noise, check a belt for lack of wear and damages, and also working surfaces of pulleys.


 
2. Measure by the special device a generator drive belt tension. In the absence of the special device check a belt tension, having pressured him by effort 100 N (10 kg) in the place located on identical removal from pulleys and measure a belt deflection.

Generator drive belt deflection when checking a tension:
New belt: 7,5–9,0 mm//64–73 kg
The belt which was in the use: 9,0–10,4 mm//39 kg
Check: 5,0–6,0 mm / 34–49 kg
Deflection of a belt of the drive of the generator and pump of the amplifier of steering when checking a tension:
New belt: 8 mm
The belt which was in the use: 6,0–7,0 mm
Deflection of a belt of the drive of the generator and conditioner when checking a tension:
New belt: 6,0–9,0 mm
The belt which was in the use: 9,0–10,0 mm


Prevention

The belt which worked on the engine more than 5 min. is considered the belt which was in the use.



Measurement of a tension special device

PERFORMANCE ORDER
1. At measurement of a tension of a poliklinovy belt the device should not concern other elements of the engine.
2. Adjust a deflection or a tension of a belt of the pump of the amplifier of steering.
3. Tighten an adjusting bolt.
4. Turn a bent shaft of the engine on several turns.
5. Check a tension of a belt and, if necessary, repeat adjustment.
