1. Check the gap between the clutch sleeve B and the compressor pulley A with a feeler gauge. The nominal gap is 0.15±0.15 mm.
2. Turning the pulley, repeat the measurements in three more places.
3. If the gap exceeds the allowable, adjust it with shims.
4. Connect the wires of the compressor to the terminal «-» And «+» battery. Check the operation of the electromagnetic clutch by the clicks it makes.
