Help AC Compressor Pulley??

[naturerunning]

Hi everyone,

This is my first post, so bear with me. I'll preface this post by saying thank you to everyone who has contributed to this forum. I have learned numerous things.

So I'm replacing my radiator and came across what looks like a bad ac compressor pulley? I have a decent manual but it's not Toyota. Could this be normal? If not, does it require addressing it immediately? TIA

I have a 94 FJZ80 stock 4.5L w/138k

Replace it.

@inkspot thanks, I figured I'd have to. Anyone here know the part number? I'll probably just call Toyota and give them my VIN

Looks like the pulley bearing is wasted, but that usually takes out the snout on the compressor. In most cases it's best to replace the compressor assembly. DENSO 4711166

Is this as simple as pulling the belt, taking off the pulley and replacing ?

To replace the compressor will need to discharge/recharge the system. I would also replace the dryer. DENSO 4780503 or the slightly shorter one DENSO 4780500

Thank you very much! Anything while I'm in there?

I know Denso technically the same (I have had some issue, although

I've had a maybe an issue or two with denso products (not labeled Toyota) and just want to be sure this is a reputable replacement for the AC compressor. In addition, is there anything else I should address while I'm 9n there? Thanks again!

Then buy it in the red box from Toyota? We have had good results with the ones out of the blue box.

I don't know the issues with your Cruiser, so cant answer. Did the A/C work well before the failure? Some like to replace lots of random parts for a "piece of mind"....

There were no issues that I was aware of. But the pulley looks shredded. To be honest, we rarely used the AC. We are mountain ppl and enjoy the heat so it's hard to remember when the last time I used it and how well it really worked.

The pulley is part of the clutch, it is included in the compressor assembly.

The parts should come with the needed seals, if you want to be sure, something like: FOUR SEASONS 26749

The compressor comes with the correct, oil, usually slightly excessive amount, so enough to replace the dryer, could order some oil, like: DENSO 9990101 or FOUR SEASONS 59007

Of, if you never use A/C, cut the belt off and drive happy!

and the factory service manual can be downloaded from here - FREE: For Sale - 40, 50, 60, and 80 series FSM for a hell of a price.

Be sure the clutch didn't break apart and get into the system.

To be honest, having just rebuilt my entire AC system, I am in the "replace everything and make sure your lines are in good shape or replace those too" camp. I bought all of the components from Rock Auto and I picked all the Denso stuff. I had to buy two sections of hard line from Mr. T and a new drier bracket too. The whole thing, including the manifold gauge set and vacuum pump I bought was around $800 and I wouldn't do it any other way after having gone through it. I think most people came to the same conclusion I did after getting into it.

A/C system - how to remove the cooling unit, evaporator, expansion valve

Just want to make sure you understand that breaking open the A/C system will require special tools to put back together. Vacuum pump, manifold gauges, etc. Often these are available for rent or even rent free from various parts stores. Also, if you crack it open, you'll need to replace the drier and add oil. I'd also replace the expansion valve while you have it open. Other's will be able to add to this. And you have a '94. Not sure if that is R12 or R134? R134 is readily available and inexpensive. R12 isn't. You can convert, but more work and some aren't happy with the results. I converted my '93 from R12 to R134, and it has worked great for me. But then again, I'm in Western Oregon, which ain't extrememly hot.

Good luck.

Mine is '94 and it has R134a. I think the cutoff was 5/93 build date and later.
