A/C Bracket broken, lost both belts

[Gawernator]

So, I looked at my 944. I wanna cry lol. It looks like somehow when I started the car, the bracket holding the A/C compressor (I think) broke, and the compressor is hanging off. The belt and the PS belt also are AWOL. I'm not sure if this affected the alternator... I'm still trying to figure out how it all goes together.




What do I need to do? I can't tell if the A/C compressor is damaged or not. It looks like some metal part on the top of the compressor is sheared off, or something. What bracket will I need? In the pictures if you see anything else broken please tell me

The bolts that mount the ac compressor to the bracket, have been known to shear off. The bracket also houses the alternator. You deffinately need a new compressor, or you could take this opportunity to delete it, by getting a non-ac alternator bracket. The adjustment rod is also broken.

To get at everything,
Take airbox off,
Take alternator off (2 bolts)
Take bracket off (4 bolts)

Unfortunately in this case instead of the bolts braking, the compressor housing broke. I think the reason is.... When adjusting the ac/alternator tensioner, the ac compressor bolts should be loose. If they are not, the compressor is basically bolted in place, and strain is put on it, in whichever direction it's moved by the rod.
Only after the belt is tightened and adjusted, can the compressor bolts be torqued.

As it just so happens, I have an alternator/air-con bracket from my '83 that I've been trying to get rid of FOREVER. If you need a new one, how does $30 plus shipping sound?

Here's the part I am talking about.

But it's impossible to tell from those photos whether you need it.. Something similar happened to me while I was on the freeway, driving home from Detroit. I had to pull into a cul de sac and do a patch repair at 2am because my battery wasn't recharging anymore. Not fun.

Anyway, the middle picture looks like your tensioning strut broke maybe, in which case the compressor would drop and indeed throw your belt off. Basically, from the LH side of the car, looking toward the rear, the motor sits in the middle, and a big aluminum bracket is fastened by four bolts onto the block.

This bracket supports your alternator, and the compressor bolts into the bottom of the alternator (if I remember correctly). So it could be that a bolt holding your compressor to the bottom of your alternator sheered off, which incidentally was my problem. The chances of the alternator bracket breaking are pretty slim. Or, like I said, it could be the tensioning strut, which braces your compressor at the bottom against the bottom front of the block, broke.

This all sounds very confusing, now that I re-read it. Hope it helps a bit..

Okay, so it's not possible to have a shop weld/repair anything in that situation? About that bracket, would it fit on my '86 without problems? What is the adjustment rod and what is the tensioning strut? Also, the bracket that holds the A/C compressor and the alternator is one and the same then?

Correct, they are held by the same bracket. With the air box out of the way, it should be very easy to see whether or not said bracket is intact.

The adjustment rod and tensioning strut are one in the same. Different strokes for different folks. Different names for different dames...

Further than that, I'm afraid I have no real knowledge. Good luck.

I agree a bit hard to visualize, hope this helps...



A picture is worth a thousand words.
The orange dot is where the tensioner strut mounts to on the compressor.
The green and purple lines are bolts that mount the ac compressor to the bracket
The red and blue lines are the bolts for the alternator

The ear on your ac compressor (the one that takes the green bolt) is broken.
How's the green bolt ear on the bracket?

You can also see the tensioning strut rod end, sheared and still attached to the compressor. (orange dot)

I have a bracket off an 83, no charge, just shipping. let me know.

[Rasta Monsta]

I doubt the bracket is broken. He just needs to get new mounting hardware, lay under it, and put it all back together.

[944 Ecology]

83 brackets will not fit 86 cars... Ask me how I know.

[Gawernator]

Wow that really helped a lot. Thanks so much for the support guys. I would really prefer to keep my A/C system working, since it was already converted to R-134a EDIT: Wouldn't an early bracket not fit since the later models have a different alternator?

[Toran]

Wow, just look at the amount of help and support coming!
So happy to continue to experience this support base over the years.

Gawernator you'll soon be up and running

[Gawernator]

I hope so. I have until Friday to get it fixed, missing work in the US Navy is /not/ fun

[ernie9944]

Diagrams of your AC/Alternator system,hope it will help.

[Toran]

Hang in there bro, you gotta lot of people rooting for ya!

[Gawernator]

After talking with my dad. I think what I'm going to end up doing for now is removing the compressor, I'll lose the refrigerant but R-134a is a lot cheaper than the freon I bought for 60$/lb lol. Get a shorter belt to bypass the compressor. I think I can drive that way until I have more time/money to fix the A/C system. Also replace the power steering belt.

[Toran]

Quick thinking and good short term solution to get ya back on the road!

[Gawernator]

Thanks a lot for the diagrams and images. Very useful

If you delete your A/C compressor you typically install a different alternator bracket. This bracket repositions the alternator where the A/C compressor was allowing you to use the tension strut (which is broken on your car) to adjust the belt tension. You can't just delete the compressor and put a smaller belt on there (as far as I know) because there's no way to adjust the belt tension.

If your long term plan is to retain your A/C, then I wouldn't bother with a temporary A/C delete set up. Once you find out exactly what's broken and needs to be replaced, post and update. I have at least one spare compressor and mounting bracket collecting dust in my garage but I'm across the country so it's not going to get to you in time.

I know a guy in Tucson with a ton of parts, and he knows a few guys in CA with tons of parts so I'm sure you can get what you need quick and cheaply. send me an email if you need those contacts.

I got the airbox off, and jacked the car up. Here are some photos of what I am seeing:




I think the bracket is intact. It seems that the compressor is okay but the top mounting part is sheared off. Do I really need to buy a whole new compressor or could the broken mount part be welded back together? I know I will need a new tensioning strut. I'm not sure if I am missing any mounting hardware or not.

Looks like one of your compressor mounting bolts is gone. You'll want to check the threads on the other one to make sure they're still usable.

welding that tab back onto the compressor (provided that you still have the tab) is probably possible, but if I were you I would not bother unless you know a welder who is going to hook you up for cheap...but even then it depend on the break. if it's a clean break and in a place that is accessible, your welder may be confident that he can get it back in the exact same location. if he doesn't you may have a real headache trying to get the compressor back into the bracket.

On the other hand, a used compressor is always a gamble but I'm sure there are quite a few sitting in people's garage like mine who will let you have it cheap of for nothing. Of course, you also have to factor the cost of the recharge of the system but that won't be keeping you off the road.

I personally don't use the A/C so I'd delete it, but that's me.

If you do decide to go for the welding, I'd probably remove the mounting bracket and take it with you so your welder can make sure the two pieces fit properly.

hopefully someone will chime in near you with a spare compressor laying around. Might try contacting some of the Spec944, NASA, SCCA boys near you (maybe a thread search). I bet they have a few compressors collecting dust.
