Toyota Denso AC Compressor bearing and Idler bearing replacement

[Captsolo]

Has anyone actually done this with the pump installed?

"Pulley will come off with a gentle pull" is definitely not working for me. Been at it for almost three hours now, and the inner race hasn't budged from the pump.

I honestly don't believe this can be done with the pump installed.
Edit-
I would highly recommend not trying to do this on the vehicle!
There is very little room to work, and you're just going to get extremely frustrated.
I took the pump off, and secured it between two 2x4's to get the pulley off-

Then I had to get the bearing out of the pulley- also not easy. Started out by tapping the "stakes" out of the way-

Then getting the bearing out-

Bearings-

It's easy from there [emoji1598]

You must like big headaches.

When my 2005 SR5 4runner airconditioner failed last summer I took it to a roadside AC joint called "Beat the Heat" (not some fancy AC place or the dealer), and he tested it with dye, and when it wouldn't hold a charge, the one tech that worked there (no car lifts, some used AC equipment) said get a new compressor and I'll install it, and charge, etc. for $200.

So I got a new denso at Amazon for $188. "Beat the Heat" installed it the day I brought them the denso (same guy/one Technician did everything),and I've had "cool" like when the car was brand new.

No dryer installation, No other A/C parts.. just great air again.

Total cost was $400.:car:

BTW.. I asked him about rebuilding the OEM Denso, and he said just throw it away.

Took him 4 hours - no waiting on previous customer cars - just a great job. :horn:

I've noticed some pretty loud whirring/grinding coming from the AC Compressor area and realized that the AC Compressor pulley had some play in it while spinning.

I was assuming the AC compressor pulley bearing was the culprit, but now am wondering if the idler pulley could also be involved also since most people seem to have issues with that pulley.

I'm still hoping to replace the AC Compressor pulley but seeing as there are mixed responses on whether this can be done with the compressor on the car, I was wondering if anyone could give some insight before I get into something that's over my head. Thanks.

I personally would just replace the denso ac compressor then rebuild it. Especially if a bearing failed. That way it's all new with good seals holding the refrigerate in the system.

Oh yeah, you can replace the bearing while the compressor on vehicle. I have done this to my 92 Corolla, 90 hilux, 97 4runner and 00 Landcruiser. Make sure to use NTN (or branded) bearing. All these 4 vehicles had the same identical bearing! The AC system (except the bearing) on all 4 are still FACTORY and never had to recharge!

Do NOT use chinese bearings. I once used a chinese bearing and it lasted JUST 7000 miles!
