Renewing pulley, version
“1”
Note
If the pulley overload protection device has been triggered, check that the air conditioner compressor can rotate freely before renewing the pulley. If the air conditioner compressor does not rotate freely, renew the complete unit.
It is not always necessary to unfasten the air conditioner compressor from the engine to detach the pulley

The pulley with drive plate and cap is available as a replacement part (single part number). The pulley and the drive plate are held together by a bolt (bolt is not required; can be disposed of). This bolt is used during manufacturing to insert a pre-determined amount of a specific grease into the thread of the drive plate (sufficient for fitting the drive plate onto the compressor shaft once; do not re-use a drive plate that has been unscrewed)
