1969 Barracuda Fastback
AC clutch:
Pulled/pressed out the clutch bearing, taped the bearing seat surfaces with aluminum tape and got both AC clutch parts bead blasted. Primed and painted the parts, carefully sanded off some burrs on the clutch surface, and installed a new bearing. Bearings are available from different vendors, here one example:
Timken Air Conditioning Compressor Clutch Bearings 5206DD
I left the bearing overnight in the freezer and heated up the pulley assembly. The bearing then actually fell into the bearing seat. When pressing in the bearing, the bearing seat has to be supported otherwise the pulley assembly might get bent and damaged.
The hub and shoe assembly spent also one night in the freezer before it got pressed into the bearing and pulley assembly. Two snap rings secure the bearing and the clutch parts.
I still don’t know how critical the condition of the clutch surface is, but the surfaces on the hub and pulley I am working on looked ok to me. The shop manuals states, that hub and pulley assembly should never be changed separately because the parts are mated.
I hope there will be enough friction to create accurate torque for the compressor – will find it out!
