Hi Rick, Nik_Lee, EssDub,
I have one of the Shift Linkage Roller Bearings from the Senol buy, but I don't think that I will use it.
I am concerned that the hardened & curved outer race will wear the surfaces of the Shift Lever.
I reckon that the flat surfaces & soft material of the block is intended to be sacrificial.
I like EssDub's idea to make replacements. Do we know what the material is ? Maybe something like Phosphor Bronze or another plain bearing material would be suitable.
Nik_Lee, if you want to try my bearing, I will send it over at no cost. PM an address.
