BELT PULLEY, REMOVING AND INSTALLING, "Delphi/Mahle" A/C COMPRESSOR

NOTE:

The belt pulley is sensitive to impact. Handle it with special care.

If the drive plate overload protection was activated, the belt pulley can be rotated using the outer part of the drive plate so that the A/C compressor shaft does not rotate.

The belt pulley on "Delphi/Mahle" A/C compressors currently cannot be replaced separately. If there is a complaint, replace the entire A/C compressor.

-- Replace the A/C compressor. Refer to A/C COMPRESSOR, REMOVING AND INSTALLING ON BRACKET .

Belt pulley version "1"

NOTE:

The belt pulley on the "Delphi/Mahle" A/C compressor version "1" is currently identical in construction to the belt pulley on the "Sanden" A/C compressor. Refer to OVERVIEW - BELT PULLEY, SANDEN A/C COMPRESSOR, VERSION 1 (vehicles with 4-cylinder engine). However, the drive plate is secured with a self-locking bolt OVERVIEW - BELT PULLEY, SANDEN A/C COMPRESSOR, VERSION 1 - Bolt to the A/C compressor shaft.

NOTE:

The drive plate -B- is bolted to the A/C compressor shaft with the bolt -A- (tightening specification: 20 Nm).

The spring elements (overload protection) -C- on the drive plate -B- will loosen when the torque is too high (for example, if the A/C compressor runs with resistance) and the belt pulley -D- runs freely without driving the A/C compressor.
