Since I put the A/C belt on and charged the system the pulley side of clutch has rattled very loudly when engine is running. The pulley side of clutch is made from 2 pieces with some sort of plastic or epoxy material between them. The plastic material is blown out allowing the 2 metal parts to rattle together.

The 4 cylinder Tempests with A/C used a large 6-7/8" diameter compressor pulley. I found an NOSR remanufactured clutch that was listed as fitting 1970's Caterpillar equipment.

Because the A/C system is charged I had to work on the compressor in place. After unbolting and removing front bracket I propped the compressor up on a block of wood so I could put tools on it.

I have an A/C clutch removal kit and a large pair of snap ring pliers.

What became a real challenge was making the shaft key stay in place. Because of the clutch's electro magnet, the shaft is permanently magnetized and the key would jump right out of the slot. I got it to stay by putting some grease on it and after several attempts I was finally able to get the new clutch on.

The compressor and clutch run smoothly and quietly now. One more thing checked off of my large to do list!
