Bearing ID for 74mm clutched pulley
Hey guys,
New 2005 E55 AMG owner here. Love this place! Question, I have a 74mm clutched pulley that had a bearing go bad. The pulley was put on by previous owner, cant confirm what brand pulley I have so cant locate replacement bearing. I cant find a number on the bearing. It appears to be several (4) thin bearing slid together inside the pulley. Small ball bearing inside. Can anyone help me locate the proper size bearing? Its mics out at around 2.27 inch outside diameter (inside of clutch pulley) /1.75 inside diameter (supercharger snout size). Local Napa cant find it. Hoping someone can help me. Can attach pics if needed.
Thanks!

If it were mine I would swap it for a UPD or VRP clutched pulley. UPD makes them in 83.7mm and 77mm. http://ultimatepd.com/catalogsearch/...4&engine=M113K
Hit up Shardul at UPD.
VRP has them in 70mm, 72mm, 76mm and 80mm in clutched.

Hit up Phil at VRP

Thank you for the quick and detailed response. I've heard the same about DTK. Future mods will be with the other companies you mentioned. For now I'm looking into replacing the bearing with a high quality piece. The pulley and clutch itself looks to be good.
Look at SKF.com Post pics of the bearing , what you describe a bearing in a bearing seems odd... measure to .001 and when you replace the it put the bearing in the freezer and warm the clutch up in oven to 125-150 degrees and it should drop in with limited effort
