Howdy all,

I know this is a long shot, but I am looking for a CAT 1B3730 - Berliss OR310 outer race for a pulley bearing race. I can't seem to find a cross reference and the search is coming up blank. I called 1 place online that said they have them but were out of stock and not on reorder. I found a NOS inner race but no outer. This is for the belt pully on a D4. They are about 3-7/8 id, 4.33 od and 1.75 wide. The ones in the unit are Berliss. Thanks all!

Well, it appears I'm back to square one. The eBay seller doesn't have the item in stock and never shipped it. I think I might do some measuring and see if there's another full bearing set that would work.
