Abstract: An air-conditioning compressor comprises a shaft rotationally assembled through a casing. A pulley is attached to the compressor by a roller bearing. A torque-transmitting member engages the pulley and the shaft together. Openings are formed between arms of an external torque transmitting part and a bore of an inner ring has a radius such to enable insertion of a crimping tool into the torque-transmitting subassembly to reshape local plastic features for assembly of the torque-transmitting subassembly. The local plastic deformations of the casing interfere with a transverse face of the inner ring, wherein the local plastic deformations are positioned in axial alignment with the empty spaces in at least one relative angular position between the torque-transmitting member and the inner ring.
