Air Compressor Replacement 280SE

Post by ngruzevs » Mon 30 Oct, 2017 7:56 pm

My air compressor is starting to leak quite badly in my 85 280SE, from front and rear seals. Green dye seems to be leaching out.

Can anyone recommend a suitable replacement?

Find a supplier of A/C compressors and ask them for one that is set up for your car.
There are literally thousands of them that will not fit and likely to be only 2 or 3 that will fit.
Better to get the right one.
Have your engine model and designation as well as the build year. When you go to pick it up, do a visual to make sure the hoses go to the right places, the mounts are the same and that the pulley is in the same position of the new one compared to the old one.
I found one which I was told was the right one, the hoses looked spot on but when I fitted it, the pulley was offset compared with the one I took off. Fortunately the supplier came to my place (a trip of 40KM each way) took it away and came back with my pulley on the new pump.

Thanks for pointing me in the right direction.

I do have some time as the compressor is still pumping out chilled air 2C, but the amount of dye coming out is ridiculous. I'm guessing by next summer a replacement will be needed.

I see from your photo you have the update version denso compressor, not the horrible old york one as used previously.

We got a China made knockoff on ebay brand new for a couple hundred dollars. it been going without issue for a couple years now. The oem correct ones are available for about $800 from memory. (it's the most expensive version, comes with MB pulley/clutch that costs more than the compressor itself) The compressor will have a sticker on it with the correct denso part number, make sure the one you buy has the correct pulley as there are many variants.

Have been looking at replacement for my a/c compressor on the W140. Found one Denso in Kalgoorlie but they wanted unbelievable $1300.00.
Pelican parts or Autohauz has them for about $380US. I think mine is seizing as if you turn on the ac while at idle the engine stalls. :banghead:
