For our serpentine belt idlers and the viscous heater, we have threads on what size bearing to buy and a how to replace them.

Idler Bearings

I would like to know if it is possible to replace the bearings on the AC clutch and on the fan mount?

Since the viscous heater bearing is replaceable I see no reason the AC bearing could not be replaced.

I have an old fan mount I removed 50k miles ago because of a dying bearing, I will see if it is possible to press old one out and get a size.

Has anyone successfully pressed out the fan bearing? If so, do you have a replacement part number?

Thanks.

They press out easily enough, just remember the set screw
I tossed the bearing years ago, so I can't help on that front.
