Hi,
I am going to replace the bearing for the A/C pully that is causing shrieking noises. I need the part number for the bearing. How can I find it? Can anyone post the part number for the breaking?

Thank you,

You should be able to find it here: https://mbparts.mbusa.com/

or have a look on FCP Euro etc

I found on Identifix document S-B-83.55/87f that describes the replacement of the pully. However, I can't find the pully part number. It looks like there is a replacement for the pully, and I don't need to press out the bearing. How can I fidn the part number, which is the pully replacement?

Thanks,

I would recommend replacing the pulley itself, they are made of plastic. Then you will also replace the dampeners. Coincidentally, I replaced mine not too long ago

I just broke the head of the 7mm hex bolt. From a simple job, it just became a complicated job.

I circled in red the bolt I need to extract, and in yellow the broken bolt (rust all over). The dealer has no part number for it, and I will need a replacement. Do you have a picture of this bolt outside of the pully assembly?

Any ideas how I can extract the bolt to remove the bolt?

The 7mm bolt is only a counterhold and has a threaded part for the top cover

I can counter hold with a reversed drill and an extraction tool. My next issue is to find the special tool part number:W112 589 07 40 00

The tool is expensive and will take 3 to 4 weeks to arrive from Germany. I can't find a used tool on eBay or elsewhere. Any sugegstions about fabricating a homemade tool, or finding the tool online?

Thank you very much,

I used this tool, bought it on Aliexpress
