Removal, installation and tension of a maple belt

The drive of the pump of cooling liquid with the vyazkostny coupling and the generator is carried out from a cranked shaft through wide maple a belt. In the presence of the conditioner its compressor is actuated from an additional maple belt. Belts are one after another. For removal of a distant belt it is necessary to remove the previous.

Maple it is necessary to replace a belt at:
   a) Fragilities of a belt and formation of cracks.
   b) Emergence of noise (for example, owing to a zamaslivaniye).
   c) Type damages: cross-section cracks in a framework, framework breaks, deposits in the form of dirt and small stones between elements of a framework,
a razlokhmachivaniya or lateral wear of a rubber framework, address to the Section Check of a condition of driving belts.

If the removed belt is applied again, it is necessary to keep the direction of its rotation. Before belt removal the direction of rotation is necessary for noting chalk.

Replacement of a maple belt of the compressor of the conditioner

All models

The compressor of cooling is actuated by the wide maple belt which tension is carried out automatically.

 PERFORMANCE ORDER

1. Lift and establish the car on supports. Unscrew bolts of fastening and remove the bottom facing of an impellent compartment, address to the Section Removal and installation of the bottom guard of an impellent compartment.

2. Establish on a bolt of a tension roller a natural an internal shestigrannik. Clockwise the hydraulic tension element (1) is compressed by slow rotation. Remove maple a belt. Address to an accompanying illustration.

3. Put on a new belt according to the laying scheme. Thus a tension roller as at removal turn completely to the right. Watch correctness of laying of a belt.
4 Unload a tension roller, having released a natural an internal shestigrannik. Force of a tension of a belt is not regulated by a tension roller.
5 Establish the bottom facing of an impellent compartment. Lower the car on wheels.
