I installed an almost new looking MB clutch onto my E300 and have never looked back. The clutches I purchased were cheap enough and the repair took an hour. I removed the PS pump pulley and the fastening bolts for the compressor and was able to tilt the compressor enough to remove the old clutch and install the replacement clutch. It’s performed flawlessly!

Also, the Toyota clutches that I pulled are identical in appearance to the MB clutch with the exception of the fused part and they will fit perfectly on the compressor. One only needs to modify the power supply connection.
This is the correct way to do it. The fusible link in the clutch coil was a daft idea. It eventually just fails from age rather than overheating. I did the Toyota clutch coil swap 5 years ago and the original Denso compressor is still going strong. A failed clutch coil fuse is NOT indicative of a bad compressor.

Not sure how to do this. Or what numbers I need from the compressor to order a new clutch. All I know is I am a terrible husband for having my wife drive this car around in 100+ temps

If you are at this starting point, easiest way would be to buy a replacement compressor and install it or have it installed. Changing the clutch is only a DIY job as almost no shops will do it for you.

If you own a W210 chassis car - your compressor is a Denso 7SB16C
If you own a late W124 chassis car - your compressor is a Denso 10P17C
If you own an early W124 chassis car - your compressor is Denso 10P15C

remember that you need to order the clutch for the above you need to be specific to mercedes benz as the connector for the clutch magnet field coil is unique to Mercedes and BMW - If you buy a toyota equivalent, you will need to splice your old wire to it.

Thank you. It works intermittently so I am believing its the clutch. I've had the refrigerant checked and its fine. Thank you for those part numbers!

The clutch is a coil of wire (sometimes with a fuse or thermal fuse embedded in it). It's good or bad, it won't be "intermittent". You likely have a control or wiring problem.

This listing says its for 1995 Mercedes, having tough time finding it elsewhere as just the clutch, I found the whole compressor for $250.

This is a GM clutch, it has the delphi weatherpack connector.

Your town doesnt have an AC compressor repair shop? They sell entire compressor clutches all day long.

Exclamation

Lucky me, I saved the AC compressor from the donor car when I did a motor swap 2 years ago! I wasn't sure if I had saved this.


Now the question whether to replace the whole compressor or just the clutch. The donor car had about the same mileage, wasn't sure about the AC though because it was bought in cold temps and I never tried it.
