Fit In Five Steps

How to replace an A/C Compressor Pulley Clutch Bearing?

1.Lift The Compressor

The objective is to replace the AC clutch on the car. Remove the AC compressor’s front and rear bolts only. Lift the front of the compressor up to clear the top radiator support. Maintain the compressor in that position by placing a block of wood between the front of the compressor and the top of the engine. Do not depressurize the system or remove any hoses.

2.Locate The Clutch Bearing Assembly

Locate and if necessary secure pulley key. If the key stays on the compressor shaft, do not remove it. An even bigger snap ring secures the coil assembly to the compressor. Remove the snap ring. Examination of the old pulley and clutch offers no clues as to why they malfunctioned. There is some oil residue on the pulley face, but the surfaces appear to be ok.

3.Removing Clutch Bearing Assembly

In removing the clutch it appeared the coil was permanently energized. The clutch removal tool had to forcefully pull the clutch from the pulley. I was not about to put this evil coil pack back on. I cleaned the contacts on the rebuilt unit prior to installation. Gently clean the nose cone to remove any surface rust. Don’t be aggressive here, the clutch bearing rides on this surface, it must not be compromised.

4.Install New clutch Bearing Assembly

Offer coil pack to a compressor and install. Make sure the coil pack is orientated properly to connect the electrical connector. There are three projections on the rear of the coil pack that must match the corresponding holes in the compressor body. Install big snap ring. Clean pulley surface and install pulley. Install second snap ring.

5.Replace All Parts In Reverse Order

Install compressor to an engine. Tighten 4 bolts to engine bracket. Connect electrical connections to the coil assembly. Install belts.
