Planning for a 4000 mile trip during the summer so I had to be sure the AC was good. I noticed slippage under acceleration and highway speeds.
Removed the original AC clutch:
The electromagnet looks fried. The pulley face is worn out. Front plate looks bad too.
On the right is a used replacement. Looks much better.
There is a friction disk bonded to the pulley as seen on the left. When it wears out, it looks like the pulley on the right.
If you have a high mileage truck where the AC is used a lot, you should inspect your clutch to make sure it isn't worn out.
I had previously replaced the bearing and didn't stake the replacement. I found the bearing pulled out approximately a millimeter after a year of use. So a replacement bearing definitely does need to be staked in.
I tried to find a new clutch from Honda vehicles. We have the largest of the TRSA series compressors and the shaft diameter is larger than the smaller (though otherwise virtually identical) compressors used in Hondas.
