so I am changing to a 64 mm I got off the form, looks ok but would like to put in a new bearing,can’t find the part number on the form. Could somebody give me the part number for it?
Thanks
Dan
Pulley bearings are listed in this PDF I did some years back.

You should be aware that this pulley might fail causing severe damage to area around the pulley, you should at least fit the pulley shield made by one of the members here, Latemodel21 is his handle.
If this pulley is aluminum I would not use it at all. If the rivets are loose do not use it. If the bearing is 55mm diameter you should not use it. The weakness is the wall thickness over the bearing, the material and the dog bone springs.
It should have a 47mm diameter bearing with a 5mm spacer.
All these after market pulleys will fail, the OEM pulley will fail one day, but not likely too soon, although their have been reported failures of them as well.
The earlier produced pulleys are disasters waiting to happen.
