Hi folks. Hoping for some feedback here before I get in deeper trouble than I already am. My 89 B2200 had a locked up compressor when I got it. So a couple of weeks ago I found a decent looking compressor on an 87 or 88 b2200 in a salvage yard. I dont think this compressor had ever been run because it had the plate bolted on back where the ports are and a sticker saying what refrigerants and oils are compatible. The lines were disconnected. I bought that compressor. When I got it home, I found that the rear cover is clocked different from my old one, meaning my lines would have to twist to attach. I unbolted the cover to clock it and there are a couple of locator pins that wont allow me to clock it. So now I am looking at going back to pullapart to get the lines off the other truck. Since they weren't bolted to the compressor in that truck, I'm not sure that they even will bolt up. And if they do attach to the compressor, I wonder if they will also bolt to the condenser in my 89. I cant find much info on this topic so I am hoping somebody here can steer me. Any help would be appreciated!

 

"If" that compressor was the correct one for THAT truck, then go pull those lines (may be separate or a combined manifold, depending on year). The last four digits in the compressor model number determine the orientation, etc.

Since your 1989 had a locked-up compressor, likely particles/debris got in you condenser, lines, and drier; backflush the lines with solvent through condenser, then blow out the solvent.

The condenser should be the same, but new condensers are no longer available. Possibly you want to pull all the AC stuff you can.

 

I went back to that salvage yard Sunday and the lines were individual and the truck was an 87. I didn't see any kind of bracket to hold them together and bolt them to the compressor. I'm thinking I will take my old line assy to the hose shop in Birmingham. As far as shrapnel in the condenser, I am planning to flush it and hopefully replace the dryer. But hopefully just a bearing seized and there's not a lot of debris. Thanks for all the info and advice!

 

My 1988 B2200 AC compressor has combined manifold hose assembly (think a Y-type shape) and there's a single bolt that holds that onto the compressor.

Best scenario is getting hose shop to do their stuff. Actually BEST scenario is to get a brand-new compressor if you can find one.

Way back in early 1990s, I did buy a used AC compressor for my 1984 Jeep Cherokee, and that worked out fine. On the used one you bought, test the AC clutch first (electrically and listening/feeling for resistance when you spin the pulley by hand), and also turn the compressor drive plate clockwise (should have only medium resistance to turning), should pump some air out the high pressure/discharge port.

ALSO - SAVE THE OLD COMPRESSOR - THE AC CLUTCH COULD COME IN HANDY SOME DAY, OR EVEN ITS REAR PLATE !!!

 

Thanks for the info, again. We finally got a little break in the heat this morning, and I might wait till Spring to screw with the A/C, but it's good to know I should ****** up certain components. One of these days I will get around to putting up some pics of my truck. Have a good weekend!

 

Not a bad idea to wait for spring.
