Parts for 93 Corvette

LoJo on Thu May 27, 2010 5:30 AM User is offline

Year: 1993
Make: Corvette
Model: LT1

Hi,

I sent a message via the website form over a week ago, unfortunately I didn't seem to get a reply. Can I ask my question here instead?

I have a 93 Corvette LT1 which has developed a leak from what seems to be the front compressor shaft seal. The system is also R12 so will need upgrading to R134 for use in Spain (where I live).

Could anyone please advise me what parts I need to order to do both the leak repair and the conversion?

Compressor is marked... Denso - GM10135691 - 247100-3 002 - 10PA20C 12V.

One thing I have noticed whilst browsing the website pictures, is the drier/accumulators (think I have those identified/named right) do not appear to look like the original Covette part... is it a case of fitting a patent/different part?

Many thanks for any info.

First off, sorry for missing your email. There are a few that slip through our system and we don't get recovered from the Junk folder. The Corvette's are known for not having the best functioning A/C system from the factory with R12, so with R134a the performance is less than desirable. My recommendation is to replace the shaft seal and recharge with R12. Being overseas it should still be available. It is expensive but it can be found. As far as replacing the shaft seal, you will need to tools to remove the clutch, pull out the shaft seal, install the shaft seal and install the clutch. Being that it is a 10PA20C compressor, I am not sure if the GM kit will work for it or the 10PA15-17C kit will work. Chevy had a A/C system switch in 93-94 where they changed the parts in the system and depending on built date, it could be either accumulator. Your best bet is to post a picture so we can match it up. At this time we do not ship outside of the U.S. or accept payment so you would have to arrange some form of payment/shipping within the U.S. if you were looking to purchase the parts from us.

Hi Adam, thank you for the reply and no problem with the missing mail... it happens.

As far as my research has shown, R12 is no longer available in Europe. I beleive most of Europe signed up to the ratified Kyoto agreement which seems to have put an end to R12 (legally at least!).

It would be no problem buying two seal kits (is this what you mean) to cover both options.

I will get a pic of the system and post later (it's 4am here at the moment).

However, it looks as though my biggest problem will be payment/shipping, I don't have anyone in the US. Would there be any chance that you would consider direct payment/shipping?... I really wouldn't mind or complain if you wanted to keep the payment in your account for a week or more prior to shipping (I have amex if that is any good) and I also wouldn't mind waiting until it was convenient for you to actually ship. I would only need USPS which arrives safely in about 7 days. Any chance please, I'm stuck for any decent 'corvette knowledgable' suppliers here!

Hi again,

Here is the requested image:-



Thanks again.

I am going to say that the AMA listed dryer looks EXACTLY like the dryer in your pictures:



Now as far as the tools to swap the seal - you will have to wait for one of the GM specialists here to chime in.

A reman compressor is about 550 USD. It may be cheaper to buy the tool set, but only if the compressor is in good shape otherwise...

Thanks bohica2xo, I hadn't seen that one... found it now thanks to your info.

I suppose reman prices, although expensive, reflect the work involved. The bug with being in Europe is the shipping charges for heavy parts from the US and then import/tax duties on top of not only the part(s) but also on the shipping. I've had some parts shipped and ended up paying almost double the shelf prices... gotta love the taxman!

We have those remanufactured units available for $321 but again the problem lies in the shipping and payment. If you would like to give them a call. I have taken payment and shipped to a company called Bongo U.S. What they do it, they accept your payment, call us and pay us with a card of thiers, I ship it to them and they ship it to you. I am sure they charge some kind of a service fee but it would be worth looking into if you are interested in purchasing inside the U.S.

Hi Adam,

Thanks for the info. I looked at the Bongo site you suggested and it seems as though my first step is to establish what parts I need from you and then your estimate on the parcel size and weight so as I can get a price from Bongo.

Is it possible to give me a list of parts you recommend so that I can repair the compressor and do the full R12 – R134a conversion?. I’m not worried about tools and purging/recharging etc., I’ve decided to source the parts (none available in Spain) and then get a local garage to do the work.

I’m still not sure where you said in post #2… “Being that it is a 10PA20C compressor, I am not sure if the GM kit will work for it or the 10PA15-17C kit will work.”… are you referring to a compressor seal kit or a R124a conversion kit or something else?

Thanks
PS: Don't know if this image helps or is accurate, it is only one I found on the net.

I can't seem to identify/list the parts I need to repair my system. Nor can I find a local (Spain) a/c company that is familiar Corvette systems who inspire any confidence.

Can you tell me if you can supply (and advise me what they are) all of the components so that I can replace the complete a/c system.

Thanks.

All of the parts you need can be purchased from our site here, 1993 Chevrolet Corvette 5.7L. All of the parts are available and ready to ship. You can calculate the shipping weight by the amount shown on the item that way you can give Bongo an accurate weight. You will want to replace the compressor since it is leaking, accumulator, orifice tube, and have the shop you are taking it too, flush the condenser, evaporator and hoses. The condenser isn't ideal for R134a but it will somewhat work. You will also need adapter fittings shown here depending on the size of your current charge ports, and a conversion label as well as a Low-High pressure cutoff switch to wire into the clutch coil circuit.

Hi Adam,

I did look at that link and couldn't find some of the parts I 'thought' were needed... I'll go and check again.

Is there an alternative condenser that will fit and work better?

Will also go looking again for the extra components.

I have also been reading your faq's and I'm wondering if my entire system is contaminated with 'black death' and I need to replace the whole shooting match.... The leak around the compressor shaft and on the inside of the engine bay hood appears to be like the black sticky/semi-hard deposits in your pics!?

I'm trying not to get this wrong as ordering the wrong parts is going to be real expensive if I need to exchange any.

Hi TRB,

As discussed, here are some images. Does this say anything to you?


This is the splatter on the inside of the hood. It resembles a kind of 'pebble-dash' (if that term is used in the US) effect and is mainly black... must be the camera flash that makes it appear brownish!



This is the point of the leak, as splashed up onto the pipes... in-line with the front and rear of the pulley.



This is the texture. Like a sticky/black silicon gasket sealant... seems to slowly harden the longer it's left.



[edit] For info: This all started when I first went to use the AC this year (I guess the seal had dried). Compressor clutch initially pulls in for a few seconds and then releases and does not re-engage whatever temp is set on the dash.

The biggest problem I have is, Spain is not the best place for advice nor AC repair specialists. I have learnt from past experiences that getting any kind of engineering work done (quality wise) is a nightmare and as soon as I say Corvette it's a total non-runner. I don't even mind stripping this compressor down to total component level... if I can get the bushes, bearings, seals etc.


Thanks for any info/advice.[/edit]

I would not say you have a black death issue but by looks of it your compressor is not in good shape. Hub looks burnt which caused the seal to fail. Again just observations looking at your image.

Thanks TRB. Totally accept that is based purely on images, but your comments/opinion sound very logical to me. Would you think (only another remote guess asked for) that the hub burn-out is due to high friction heat, bearing failure or coil heat?... just curious as to how these things usually fail.

Would you suggest I change the clutch/hub and replace the shaft seal (compressor seems to rotate freely) or the whole unit?. If the whole unit do you have any opinion on your new v reman units?

What makes me baulk slighly at the thought of a complete unit, is that I have to add about 25% to the final price due to import taxes/duties on all parts and also on the shipping costs... the taxman really clobbers us and often makes US imported goods unviable!

Also, reading your comments and in FScammel's thread, do you know how well that alternative condenser physically fits in a 93 vette and would fitting that condenser bring the system performance to a good/reliable level in the case of a R134 conversion?. Accepted and understood that pipework is involved. Importantly and referring to your comments in the other thread, would using this alternative condenser allow for the system to be charged to the proper level/pressure thereby giving the compressor/system normal service longevity???.

Thanks for all your input, I'm starting to get a much better understand of the problems and conversions with your explanations.

[edit] PS: I have just been making phone calls about recharging at local garages... it seems that no one can supply R12 locally, so it appears I might be committed to trying to convert [/edit]
