4.4. 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 • m
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.
