The bearings can be replaced, but you need access to a hydraulic press, or find a shop that does.
Spokane? (looks like it) Check the western meets section and come down in April. We can do it then. Free room and board, but it may be crowded.
Also check out the WCBF topic in National Meets.
In a nutshell, it'* fairly simple to do the coupler, and not much harder to do the bearings, but you have to have the right tools for the bearings. Coupler only requires basic tools and the right materials.
has the bearings, coupler, and oil. INTENSE may also sell the bearings, I haven't checked recently. They DO sell the oil, gasket maker, and coupler. I strongly suggest red gasket maker (either GM, loctite, or permatex) rather than standard RTV.
