I just looked at my factory Ideler and it has an NTN 6303LHA bearing. Yellow seals on both sides. Intersting how they took two stamped cups and stuck them back to back withthe bearing trapped in the middle and then riveted it together. Much cheaper than machining a pulley, but not easy to fix. It's a throw away part.

My LET bearing still feels like it is in excellent condition. But I dont have a ton of miles on it either. So I will put it back in and use it until Jerry comes up with the replacement. I just got a new 115.3" gatorback but that wont handle the factory idler. I got it to give a little less tension on the tensioner.
