Dash A/C Compressor

[truk4u]

Any suggestions where to buy a dash A/C compressor other than Prevost? The part number below is for 134A, but can be used with R-12 after changing the oil from Ester to Mineral.

CCI/York
Model ER 210L
Part # 25149

Prevost part # 950393 - 295.55

Tom, Just saw the post. I think that is a pretty good price but I will get-on-it right away and let you know what my contacts say.

[JIM KELLER]

Tom, My Napa contact said the " L " designates left hand suction. They have them but only in Rebuilt Units. Our cost is 103.39. They said they would like to have the old unit to match up to be sure. For the application on a Bus I don't know how comfortable I would feel about a Rebuilt. The problem the York Compressors had was failure at high RPM's. We used to keep them in stock because we sold so many of them. Nowdays they are harder to find. I have watched the pulley and clutch on mine and thought it turned slower than an Automotive application so perhaps a Rebuilt would be O.K.

Tom, If you want to go the Rebuilt route, here is one on eBay from a very reliable source. Total cost including shipping and tax would be $131.

Tom, If you want a new unit, send an email to the place below with the part #, and they will respond with a price for your compressor. They are significantly cheaper than other sources I have found for my OTR compressor.

Tool Man - Thanks, I think I'll stick with a new one rather than rebuilt. The one I have was bought by Brian in 05 from Prevost, so it really didn't last long, even though it was new. Maybe about 3 years is all you can expect out of these compressors.

Dale - Appreciate the lead, will call them tomorrow.

Tom
You are scarring me mine is a 1991 york. What exactly went bad on it?

Greg,

It's leaking on the back side of the compressor and I assume it's a seal problem. The one I have that Brian bought from Prevost was suppose to be the improved version, but who knows. If yours is still working after all these years, you must have a good one!;)

[Darrell McCarley]

TOM......I bought and installed a new compressor from Prevost. After 8 cans of 12oz freeon, I had a leak on the back side of the compressor from the overflow pressure release port. I has a restriction in the evaporator located on the driver side under the power steering resevoir. Replaced the evaporator , converted from R-12 to 134a. It has cooled very well for the past year.

Tom, maybe Prevost meant it would improve their sales volume on that compressor.....

Tool Man - the "L" in the model number means "left hand suction" as the compressor will work in any rotation configuration.

REFRIGERANT 134a

Darrell - I wanted to change to 134a, but got the shock treatment. Since mine doesn't have Barrier Hoses (red/green instead of black) they claim the conversion won't work. The hose conversion from Prevost is 759.34, but the bad part is 40 - 50 hours labor. Prevost says they have to access the system mid coach to change out hoses, but my understanding was there was solid cooper pipes from front to rear with only the front and rear hoses needing changed.

I still have homework to do on this hose issue.

[JIM KELLER]

WOW ! Looks like you are DEEP into research on this project ! Perhaps you should find the hose manufacture, go directly to them and determine if the composition will support 134.

[truk4u]

Dale - Your guys came in at $350.00 plus shipping, more than Prevost. I found it locally at Fleet Pride for $227.00. There is also a standard Freightliner part number and most have it in stock. This is the same compressor that my 2000 CC used for 134a.

According to CCI the Manufacturer, the Neoprene Seal was an update dating back in the late 90's, so anything after that has the new improved seal.

[dale farley]

Tom, You should have paid the $350. The finish on it is probably more shiny than on the one from Prevost. The company was a few hundred dollars cheaper on the TM31HD that I need than most other places. They are trying to make up for it on the one you need.

[BrianE]

Tom, If you're going to stay with the R12 make sure the oil in the new compressor is mineral oil. When I installed the one you have now I had to drain the Ester Oil (134A) and refill it with mineral oil. There should be a sticker on the compressor re the type of oil it contains.

[truk4u]

Will do Brian, thanks.... I also learned the mineral oil has to be freeze mineral oil, whatever that is. CCI said not to put plain mineral oil in the compressor. Do you remember where you got the oil?

[BrianE]

Mineral oil for refrigeration is available at any reefer supply house. Grainger carries it too.
