I'm rebuilding the driven half of the TC on my 1971 Rupp black widow. I have multiple questions so I will list them individually.
1: I have new bearings for the jackshaft. They fit the shaft well, but are not tight in the frame tube. Is this normal on the Rupps? They push in with minimal finger pressure. Should they be tighter then that? It seems like they could spin in the frame tube when operating the bike.
2: I have new pads that ride on the ramps of the inner driven pulley. These are the white nylon pads that slide up and down the ramps. My driven pulley ramps show some wear/cupping in the ramp centers from years of use. Can this be compensated for with a spring adjustment, or should the pulley be replaced with the new pads?
3: I have a new spring for the driven unit. What is the stock setting for the spring? There are 3 holes. What is the effect of one hole as opposed to the other?
As far as greasing everything goes, am i putting a light coat on the jack shaft and driven bearing only, or is there more that needs to be greased? Im hesitant to over do it and get grease on the belt and inner drive surfaces of the driven pulleys.
Thanks for any and all help.
