AC Compressor failure 1- HDT- Help?

[jeffpatterson]

1990 JDM VX - LTD with the 1-hdt

So.. went out today down the Squamish valley to go shoot some kayakers.. 20 minutes later, AC blowing, I hear the sound of a belt squealing, and smell of burning belt..

The wheel on the end of my ac compressor looks to be melting something out of the side, smoke coming off it, and .. well leaves me with some questions.

Martin ( Old owner) had the entire system redone with Red Tek... seemed to be working ok, blowing cool before this happened....

So, I am guessing there was enough coolant in the system, but seeing the wheel smoking ( and throwing some melted looking plastic spots around the engine compartment- I am guessing that the compressor will need to be replaced.

Anyone in BC/Alberta ever ordered a replacement one, or know who may have a replacement around?
Please PM me or email jeff@pattersonimages.com
Thanks

[jeffpatterson]

yes

Well, I pulled the belt, and spun the wheel.. grinding, hesitation.. yep, the compressor is shot! Would love to know a part # or swap. I had a pm about checking ebay - seems to be some there for N/A spec 80's...

looks like a costly fix $$$ Good luck!
Did you just put up the truck you bought for sale?!?

Some good reading here: https://forum.ih8mud.com/80-series-tech/304332-c-clutch-replacement.html

It sounds like your clutch is toast (that's the black melting stuff), probably because it's been rubbing because the bearing is shot.

The NA 80 series compressor is too long. They use the same rear portion, the same clutch with a slightly different pulley, but the front portion of the compressors are quite a bit different and you won't be able to line up the pulley.

Take a look at yours. There's the thin rear portion, the long middle section, what I'm calling the "front" portion which is about an inch long, then the "nose" portion which the bearing rides on, then the clutch assembly. You need to remove the clutch and bearing and measure with a micrometer or even calipers to see if the nose has worn down (the ID on the bearing is 30mm and it should be a snug fit). If it's worn then follow my route...

In my case, my clutch melted because the bearing was shot. It didn't make any noise so I had no warning but upon disassembly I found the bearing was really bad. So bad that when it was wobbling it wore out the aluminum "nose" part that it rides on. I found a new clutch assembly and when I put it on the bearing slid on a little too easy and there was some play. Sure enough, a month of running like that and the new clutch died too.

What I did is to buy the $150 replacement for a NA 80 series off this website: 1991 - 1997 Lexus LX450 Toyota Land Cruiser New A/C Compressor

I used it to make a hybrid out of mine and that one. I disassembled both and used just the front portion of my JDM compressor with all the rest of the NA one. Unfortunately, if your "nose" part has worn there's no way around discharging the system so I chose to use all new parts except for that one piece that's really different between the 2 units. I also had to reuse the socket head cap screws that hold the whole compressor together because obviously the JDM ones are shorter than the NA ones because the whole unit is shorter.

The other minor issue is that the pulleys aren't identical but they're an integral part of the clutch assembly. Mine was badly worn on the grabbing surface so I used the new pulley. It will put your belt forward around 3/16" but that's no big deal. I just spaced my tensioner pulley bracket forward by that much so the belt lines up from the AC compressor to the tensioner, which is a short distance. It's way farther to the crank pulley so the slight misalignment shouldn't matter. My belt has been running for months with absolutely no wear.

Most of my cost was discharging and refilling the system with R134a (already converted a couple of years ago).

Cheers,

Adam

Check your mail

Jeff,
Had the same problem last year. Call one of the EBay sellers they can do a good job of matching our part numbers, my replacement came with a new clutch.

I hope that works, since it's easier.

I had tried contacting an ebay seller who had a HUGE AC lineup and he wasn't able to do anything for my application.

didn't get to it today,will check tomorrow.

Keep in mind that just because it sayd "10PA17C" on it doesn't mean ALL of the specs are the same. Many different pulley configs and I still think the lengths are different even though the model is the same. It would be nice to know so hopefully someone comes up with a direct swap.....

I had my compressor and clutch die on me last year because the bearing went, spit plastic over everything. You can swap out the old compressor with one out of a 95 Toyota Pick-up, fits perfectly. And for your idler pulley you can order a new one from NAPA for about $40 or take the old one to a motorcycle shop or somewhere that can press a new bearing in.

Oh, and I had all my stuff installed and tested by someone licenced I know here in Alberta. He warrentied it and double checked the belts to make sure it all fit right. Works like a charm, gets -10 in the cooler too

Hi Guys,
ok,l just check,the compressor from a 1990 FJ62 is the same as HDJ81.
Simon

 

[utopoo]

Sweet, there's another option too.

Be careful about spending money on a new clutch without pulling the old one off first

What happens, speaking from experience a month ago, it that the bearing fails. It fails silently with no warning, then everything heats up inside the clutch, AND the bearing grabs on the 'nose' of the air conditioner compressor, tearing the alloy and destroying it.

My guess is that you are up for a new nose on the compressor itself as well as the bearing and clutch. This is not a home fix and a whole new unit is going to be your solution - or recond by a compressor specialist.

ooops. Adam B had already covered this off. Didn't read it all properly before replying. Anyway, the two of us saying the same thing - a whole unit swap over is what is needed.

Adam has done well pulling the compressor apart. Not commonly done.

Thanks for all the tips guys. I found one on ebat - replace the entire thing was the way to go.

 

[simonliew]

Which model cruisercompressor did you buy?

Renewed interest in the Ebay seller and the model you ended up buying. I've had my truck (with a blown compressor) just over a year now and it was warm enough last summer that I'm going to tackle this in the next month before the temps rise.

Cheers!!

88320-60340 Comp assembly.
Most likely it is a bad comp. which siezes up and burns your belt.

Toyota want around $200.00 just for the clutch assembly and I purchased the whole comp and clutch for $165.00 shipped from the US.

Note you will want to change the condensor at the same time, these are easy to find locally.

Try Jensen Auto on Ebay at worst you could ship it out and have it rebuilt.

It probably failed due to karma. What did those poor defenseless kayakers ever do to you that made you want to shoot them?

Thanks Squash! Took your advice and called them with the specs, but they want confirmation of the housing and require pictures. I'm going to send them in the next couple of days.

Thanks again!!
