Guide To Recon. Ac Compressor ?

[omri617 18]

Hi , the compressor in my 205 is leaking gas & some oil . I was told I need a new one , but when heard the prices (600 pound ) I was shocked and looking for alternatives.

 

Is there a good guide how to recondition this thing?

You can replace the shaft seal for about £20 (a specialist a/c shop might be able to order the seal for you). There's a video guide here:

 

The alternative is a reconditioned compressor (£150-200), or try another compressor from a scrapyard.

Thanks Ryan

Well , had some spare time today and took the comp. off the car.

Opened it up and had a look inside

 

[omri617 18]

This was something strange which i dont think is related to the leak there was :

(It's not clear in the photo , but in the centered shaft , there are some shavings!)

 

anyway , this is the seal which I don't know what is it's condition , it's pretty unique I wish I'd find like it.

 

By the way , it's model is SANDEN SD 508

Crap , I found out this

The 508 is R12 . The air con guy fitted me with 134A system !!!

Hi,

 

IMO the 508 with 5 pistons is a poor compressor. A much better one is a SD709 and can be found on many Peugeots and Citroens from early '90 like XM, 605, 405, BX.

This compressor will fit straight on a 205 and can be bought cheaper than SD508(250-300 EUR for new recon one). I run this compressor on my 205 with R134A and have no problems even if it was designed to run on R12.

R12 compressors will work ok with R134A if you use the right oil, seals, drier and pressure contact.

Thing is , the hoses and everything is already made .

Do you know if the screwing and all are the same?

In the 508 (Old type , it's 2 big ones same size - 24mm )

I prefer to have a better compressor , but as long it doesn't require me to change the setup.

 

[omri617 18]

Just saw your photos , it looks nice!

Do you think it's also 24 mm "connectors screwings"

[Oigen 9 2 Cars]

Yes, the SD709 has 24 "connectors screwings".

I forgot to tell you that if you still have all the R12 components it is better to use R12 gas because with R134 this car's A/C system will be hopeless in a hot day. You can still find R12 gas. All you need is a service with right adaptors for R12 service ports.

Can I ask where you got your SD709 compressor from? I am getting close to either refurbing or replacing my compressor prior to finishing off my A/C install, and upgrading the compressor seems entirely sensible. Also is there a particular SD709 part number I need? I have found a used 7472 off a XM V6 which looks pretty similar

My compressor was bought through my own spare parts shop. It is equivalent to Peugeot part number 6453 H6 which is also equivalet with many Sanden part number according to servicebox

I really don't know the differences between all these Sanden part numbers, but if they all have the same Peugeot part number I think all be ok.

This compressor is really cheap for a new recon one, but you will still can find all the replacement parts for reconditioning yours. Mine was reconditioned by this company: http://www.teamec.be/

What compressor are you using now?

Edited July 8, 2013 by Oigen

[cRaig 273 1 Cars]

Thanks for the info. I currently dont have a compressor fitted, as I'm retofitting the A/C setup myself to a car which didnt have it originally. I shall do some more research now

[Oigen 9 2 Cars]

Do you know all the conversion parts that you'll need? Which gas do you intend to use?

Also the twin fans setup wiring is a little bit different to a single fan setup.

[cRaig 273 1 Cars]

I have all of the parts, including a new reciever dryer, a pressure switch from a 306/405 I was planning to use R134, but am slightly unsure now you say that gas is less effective in a 205 system?

I have the twinfans fitted already, as well as the wiring. Just left to fit the compressor and pipework, then get it flushed and filled

[welshpug 1,647]

any idea what the XU10J4RS etc use? got a few of those kicking about!

[Oigen 9 2 Cars]

The 205 A/C system was inefficient even with R12 because the condenser is simply to small for the job. R134A gas is also less efficent than R12 so the system will clearly be hopeless in a hot day. This means that you will see the fans working at full speed all the time untill the relays will melt. This is my problem now, but here in a hot summer day will have 35-40 degrees Celsius. Now I am searching for alternatives like duracool http://www.duracool.com/Duracool/refrigerants.html because I reconverted the system to R134A and R12 is not a solution for me anymore. Also the new driers and pressure switches that you can buy are for R134A.

XU10J4RS use another type of compressor. SD7V16 has different pipes

 

 

[cRaig 273 1 Cars]

I have found a Sanden compressor SD709 listed here for a 405 1.9
http://www.eurocarparts.com/ecp/c/Peugeot_405_1.9_1994/p/car-parts/car-cooling-parts-and-car-heating/air-conditioning1/car-compressor/?232735070&1&0ee0848f8969b56fc6f2291b7a0c9f316434d129&000077 Works out a £218 with their current discount code, which I think sounds reasonable enough

According to europarts its a SD7V16, which doesnt look too disimilar. I may try and fit one up to the sump/pulley run, as a mate has one hes just de-airconed a GTi6 install

[welshpug 1,647]

Just looked on Servicebox too

 

SD7V16QA1106 seems to be used on most XU/XUD/DW engines from around 95 on, pipes are indeed bolted on not a screw fitting.

Ah, I see! Interesting info, thanks. I may well leave mine on R12, assuming I can find someone to fill it! I guess it might be possible to find a thicker/larger condensor from a similar model-perhaps a 405, or more modern peugeot.

[Oigen 9 2 Cars]

You cannot use R12 with pressure switch that you have. R134A runs at higher pressures so the switch will kick the fans at full speed too late and also will stop the compressor too late. If you are ok modifying the radiator/fans support will be better to use R134A with a biger condenser. A friend of mine use a condenser from 206 on BX with R134A gas and the car is like a fridge inside. I have tried as much as possible to keep my car original and because of that I have used the original condenser, but a biger one can be used.

[cRaig 273 1 Cars]

Mm, I am fairly sure I have a pressure switch (or two) from the original 205 setup, so at this stage I can choose which direction to go. I generally prefer a subtly improved "standard" look, so like you would like to avoid modifying the fan surround too much, but on the other hand, if I go to all the effort of fitting A/C and it doesnt cool efficiently, it has been a wasted undertaking!

[Oigen 9 2 Cars]

Yes, you are right. If you have both gas system parts your job will be easier and you can try both ones and see which one will work better.

Good luck with this job

[omri617 18]

Well , I found a reconditioned compressor for 60 GBP. I think I will take it , instead of taking the risk of reconditioning and not working properly at last.
