A/c pulley bearing collapse

Alright guys.

Anybody ever had the title happen?

A/c still works, no play in the compressor & feels good when turning it by hand but the pulley feels like it's bearing has completely collapsed.

Took the belt off & couldn't believe how much play was in the pulley, surprised its still on there tbh

Got ya! Ha.

I put a post on a Facebook group about it, 2 people said they changed the compressor but didn't actually think about just changing the bearing & 1 person said they changed the bearing in the pulley & all was good so fingers crossed.

I will report back when I know some more for anybody else that might have this issue

You need to be clear are you talking of the tensioner pulley or the pulley on the pump. If on the pump you will need to replace the pump if on tensioner they are replaceable and dont forget to put a new belt on as its stupid not to relative to cost.

The title says the a/c pulley dude?

The compressor doesn't have any play in it & rotates without any grinding. The only play is in the a/c pulley which has its own separate bearing, is it not possible that bearing has collapsed & that is the problem?

If we are talking about this pulley below, I wouldn't waste time trying to take it off, strip it down and replace the pulley when you can buy a complete pre used unit off the bay for 30 upwards.
You will also have to factor in getting the aircon system regassed, as you will lose the refrigerant when you remove the pipes.
One thing to be aware of, the aircon system is under a tremendous amount of pressure and probably best having a professional degas the system first.

Yeah that's the one. I wouldn't be surprised if the pulley falls off when I take the clutch plate off tbh. I'm looking at doing it with the compressor still on the car so no need to remove /replace gas
