Belt pulley on air-conditioning compressor in 4-cylinder diesel engines.
The air-conditioning compressors of the 1 Series and 3 Series contain no magnetic clutch (see SBT 640104090).
With error-free operation, the drive shaft of the air-conditioning compressor is coupled via a driving plate (= torque limiter) with the belt pulley.
Replace the driving plate on the air-conditioning compressor in line with repair instructions RA 6452065.
When the driving plate is disengaged, the belt pulley of the air-conditioning compressor can be turned without driving the drive shaft of the air-conditioning compressor.
However, it must be possible to use a tool to turn the drive shaft of the air-conditioning compressor easily and the drive shaft must not block. If the drive shaft of the air-conditioning compressor blocks, the air-conditioning compressor must be replaced.
Using the repair kit for the driving plate with part number 64526989408 can prevent very cost-intensive replacement of the air-conditioning compressor.
