Crawled under the car to see what could be done to get some of the play/slop out of the clutch linkage connections and the lower z-bar looked to be a good place to start. The picture below is the best I could get with only 2 hands to hold the camera in and try to move stuff to where the z-bar stud and hole in the fork push rod could be seen. I was only partly successful.
I don’t understand why there is such a large hole in the push rod end as compared to the mushroom head pin it fits on. It’s at least twice as big as the pin and has loads of play when assembled. I made an aluminum bushing to put on the pin that eliminates most of the slop in the connection but aluminum is not going to be the longest lasting material for this purpose. The spring clip does keep it all assembled.
Am I missing something that is supposed to tighten up this connection? I’ve looked at the FSM and Brewers schematics but don’t see anything missing. The fork return spring works to keep the TOB off the clutch fingers, but that still leaves a lot of play from the Z-bar back to the pedal that doesn’t help getting the pedal past the break-over point and to its bump stop.
