Help needed - York AC Compressor Clutch Removal

Turbine1 on Sun September 21, 2008 6:44 PM User is offline

Year: 1981
Make: Mercedes-Benz
Model: 280E
Engine Size: 2.8L
Refrigerant Type: R12
Ambient Temp: 75F
Pressure Low: None
Pressure High: None
Country of Origin: United States

Newbie post (- so be nice). Have been loitering around for a couple of months but just registered today. Great forum for AC issues, have learned a lot already.
Long time weekend DIY auto mechanic but never tackled AC work before so on a learning curve here. Restoring my antique Merc, AC system was DOA when I bought it. Spent the day taking various parts off the car in prep for repairs to the system.
Specific question: How do I remove the clutch from this York R-210R AC compressor? Can't see any threaded holes on the front - but its covered in crud was getting late in the day so I did not look real close.
Thanks guys!

I think (many years ago) I used a 5/8 inch bolt to remove a similar clutch.

Yeah, standard English threads, either 5/8"-11 NC or 5/8"-18 NF also can use a belt wrench on the pulley unless you have a strong handshake type grip.

Thanks guys. Great tips. I think I can MacGuyver something together using these tips plus the repair manual B posted. I favor a firm handshake myself, but I can't manage to bone-crusher grip I would need to hold the pulley still. Will start with an old oil-filter belt wrench and see how that goes.
BTW, this compressor was a complete bear to pull off the car. I think those Mercedes Engineers deliberately designed the bracket and bolting arrangement to make it virtually impossible to remove without some special tools.
I am sure I will have more questions as this project progresses.
Thanks again,
Kev

AutoZone has free loaner tool for holding the clutch immobile, and maybe other AC tools for you.

An old V-belt crimped with a pair of vice grips also works providing that leverage, nothing beats an impact wrench for removing that bolt, now with that, you can hold that pulley in your hand. Like using lower pressure so it kind of rattles that bolt loose without ripping it out with some PB blaster. Most fun is waiting for the PB blaster to work.
