I’m in the process of going thru the hubs on my Bantam T3-C in preparation for a camping trip this summer. I have no idea of the history of maintenance on it. I pulled everything today and to me they look fine. No marks on the races, nothing loose or broken and no excessive leaks out of the rear seals. In fact nothing even really what I’d consider fresh and I’ve pulled it probably 3,000 miles, much of it at 70-75. I haven’t yet really cleaned the bearings but a good wiping they look fine. When I have pulled it, I stop and feel the hubs fairly frequently and have never felt any heat. The inner bearings could have used some more grease but still looked good, just very dark. The outer ones had plenty of grease and that is probably due to at some point a PO added a jerk in the cap. Not sure if it really gets grease in the bearings that way, especially the rear one, but it was full of fresh grease including mine. They are Timpkin made in the USA so probably older ones when things were made better. Thoughts on clean, inspect and repack if no marks or flat spots on bearings, vs replace with new.
