My 84 300SD's AC compressor just seized up. Need to get a new or rebuilt one. Is a rebuilt unit advisable? How do I flush the tiny metal debris caused by the compressor that had been grinding before it locked up? Is there an equipment to do this? Thanks for your help.

Since this is the same compressor used on many american autos of that time, the compressors are very inexpensive even new ones.
I always purchase new...You may want to flush with an alchohol and or oil based solution. There are many on the market that are good. ------------------ Benzmac: Donnie Drummonds 1991 GMC Syclone ASE CERTIFIED MASTER AUTO TECHNICIAN SERVICE MANAGER FOR 14 BAY FACILITY MERCEDES SPECIALIST 8 YRS PARTNER IN MERCEDESSHOP.COM |

gam0524,
Listen to Benzmac and buy a NEW compressor. I went through the same thing you're going through and really made a big mistake with a rebuilt R4. It was before I found mercedesshop. To properly flush, you will need to break every line and flush the daylights out of everything you can get near. You can get a flush unit which is a can with a hose and blowgun, it also has a schrader valve to pressurize it. You pour in the flush, air it up at the schrader valve and blow. The flush that I used was alcohol with some sort of citrus. Another very good thing to do, and I wish I had known this when I went through this problem, is to put in a suction side filter. You still need to flushe the system, however. You can get them at the a/c supply house. Put it in the softline just before entry to the compressor. Had I done that, my wife may not have gotten rid of her beautiful 300TD.
