AC compressor pulley/clutch assembly

Sorry that compressor is done. Here is a video of one getting changed out in a similar Mercedes and a guide on how to vacuum down and recharge the system:

Please run down these guides and report back.

Cheers, Ken

Thanks Ken.
The lines had a leak at the time so there is no gas left to be vacuumed. Once new one Installed I will have to get it properly vacuumed and refilled.
I thought the pulley/clutch assembly was replaceable. Would you please comment on this?
I will replace the compressor but just want to learn as well.
I have watched your video a few times. It is going to be a challenge for me. I was hoping that I could get away with just replacing the pulley assembly. But apparently not!
What brand would you recommend please?
Regards,

There is no external clutch on this compressor because they use an internal valve control the refrigerant. The fact that it came apart is telling me the unit is locked up. Here is a Denso compressor for $344.00 ON Amazon:

Check out the diagrams (below). Please let us know what happens.

Thanks Ken.
Forgive me if I am dragging on.
Please have a look at AR83.55-P-7685B as well, and let me have your comment.
I cannot upload the PDF version of this document.
Regards,

I am not sure what you want me to look at?

Hi Ken,
Attached is partial view of AR83.55-P-7685B that gives instruction on just the pulley assembly. So this is what I am hoping to do.
Regards,

Yes that will work if the compressor is not locked up. Can you spin the input shaft at all?

Yes I can.

Good the compressor might be okay then. Can you see why the pulley fall apart bad bearing?

My dear mechanic did not install the V belt correctly, as soon as the engine was started there was a big noise in the engine compartment. The idler pulley and the AC pulley assembly were shattered in a split of second and the V belt was split in half longitudinally. The V belt must have been placed on the edge of the pulleys and not centered.
Nice careless job! The guy's my neighbour! first and last job he did for me.

Would you please let me know how to remove what is left of the pulley/clutch assembly from the shaft.?
Thanks

There is a snap ring you will need to undo the get the pulley to slide off of the compressor but it is a machine fit so it will need to be tapped/pulled off. You have the images I have for removing the pulley send me picture of any trouble you run into so I can help walk you through it.
