Hold the clutch (really big channel-locks work, or use an impact) and remove the 12mm bolt. Pull the clutch plate off (it's usually sorta stuck). Do not loose the shims! Add or remove shims to set the gap.
Remove and take apart the connector (two screws , then it "unfolds" to release the wires -- you can probably leave it together). Remove the two screws holding the plate the connector screws to, one of them holds the ground wire for the clutch coil. Pull out the dust trap, noting which way it fits, then remove the snap ring that holds the clutch to the front of the compressor and slide it off. Remember which way the snap ring fits, it's not flat. Check the face of the clutch for damage and contamination -- a light pass with a flat stone won't hurt it a bit. There are 5 bolts holding the front cover to the compressor -- your new seal kit will have seal washers. Clean it up perfectly clean, and remove the snap ring holding the seal in. If you have or can make the tools, you can pull the seal parts out and push the new ones in. If not, remove the 5 bolts and the front cover comes off. Press out the old parts, coat the new ones with clean compressor oil and install, then put the front cover back on. Use the new circular seal that cam with the shaft seal -- it's not an o-ring. VERY CAREFULLY torque down the bolts. 1/4 turn at a time after they touch, very evenly (you can distort the housing if you don't). Re-install the clutch and you should be good to go. Worked fine for me (and I've also re-sealed a compressor). Make sure the snap ring retainer for the seal it seated correctly. The deal with the mainfold o-rings is that they are NOT green -- don't know what they are, but the black ones are for both R12 and R134a, and they have to be stuffed into the manifold, they look too big when you first try. I suspect they are fluoropolymer, not whatever the green ones are, and the green ones I took out of the leaking compressor were flattened, hard, and cracked with obvious signs of hot gasses leaking past, cutting fissures. Leads me to think that the $16 for o-rings might be a good value, considering the hassle of getting the compressor out of a W201. Not horrible, but a wrestle. Not as bad as from the wrecked W124 -- frame rail was shoved over a couple inches and I have to leave the bolts in, no room to pull them out, Peter On Jul 12, 2008, at 7:09 PM, Kaleb C.
