Hi all. Opened headstock to replace final oil metering unit (was backordered- I replaced all the others a few weeks ago), and discovered a big mess. In the few hours I've run this machine, it's eaten through about half of the brass clutch fork shoes. I didn't notice it until I dropped a little wrench in the oil and went fishing- found a locking washer (!) and a set screw, along with a plenty of gold glitter. The washer was clearly supposed to be on the end of this shaft (the castle nut is staring at you), the set screw not so obvious. The oil tube was also off to the side and not feeding oil to the trough on the fork. Lack of lubrication there is obvious with the cooked steel that ate up the brass shoes.
Looking at how that assembly works, it was obviously over-traveling when the spindle lever was down, and I discovered someone had installed both clutch lever mounts (on either end of the turnbuckle) backward, allowing a ton of play in that shaft. I swapped the lever mounts around and now there's almost no play in the shaft, but the fork can still over travel a bit (perhaps just because the shoes are so damaged?).
Beyond replacing the brass shoes, what can I do to adjust this and prevent future harm? The parts manual shows how it should be assembled, but not really where things should be- is there not normally a need to adjust any of this assembly? I'll keep hunting for a home for the set screw, and order some new oil to get rid of the glitter.
