4.4. Poliklinova belt

Removal

PERFORMANCE ORDER

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:

Bolt (V) of fastening of the generator: 15–22 N • m
Bolt 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. After installation of a poliklinovy belt adjust its tension.

Installation

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 tension:
New belt: 65–75 kg
The belt which was in the use: 40 kg
Check: 35–50 kg
Tension of a belt of the drive of the generator and pump of the amplifier of steering:
New belt: 55–70 kg
The belt which was in the use: 38–48 kg
Tension of a belt of the drive of the generator and conditioner:
New belt: 60–70 kg
The belt which was in the use: 32–40 kg
Check: 25–50 kg

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 of A type

PERFORMANCE ORDER
At measurement of a tension of a poliklinovy belt, the device should not concern other elements of the engine.

Measurement of a tension special device of V type

PERFORMANCE ORDER
1. At measurement, be convinced that turned the button of repeated installation in the direction of an arrow to establish an arrow of the device in an initial state.
2. After removal of the device from a belt, the shooter of the device will still specify a belt tension.

Prevention

It is not recommended to regulate a belt tension by hand as this adjustment will not provide sufficient accuracy and the belt can slip on pulleys. Always use the special device.
Check that the tension of a belt corresponds to the required values.
Check a belt tension after tightening of a hinged bolt and a bolt of fastening of the generator.
