Air conditioner compressor clutch: replacement and selection

When and why it is necessary to replace air conditioner compressor clutch

Operational lifetime of this component is not specified. The part should be replaced in case of its elements integrity violation. As a rule, the pulley bearing breaks down most frequently in the electromagnetic clutch of the air-conditioner compressor. Moreover, thermal damage of the coil winding insulation and breakdown of the electromagnet is also possible. The clamping plate is apt for corrosive and thermal damages. In addition it can deform.

Most of all, any mechanical damages of the clutch or its elements are the result of unqualified repair or a road accident. During incorrect installation of the drive belt, its excessive tightening can take place. This leads to friction between the pulley and the coil casing. Heating occurs, which causes negative effect on some elements condition. Particularly, the pulley bearing can destruct, the coil winding insulation can burn-out, melting and deformation of the clamping plate occur quite often.

Failures of air-conditioner operation can indicate breakage of this element.
