Atomic Monkey Posted November 16, 2014 Report Posted November 16, 2014 Has anyone else ever had a problem with the detent lever riding on the shift drum and not letting the wheel bottom in the star? On mine there was grooves worn into the drum because of so much slop in the detent lever. I spun some material off the drum in a lathe til there wasn't anymore contact between the lever and drum. Otherwise when the lever was up on the drum it allowed for quite abit of freeplay. Quote
satts Posted November 16, 2014 Report Posted November 16, 2014 Pics???are you talkin bout the bearing riding on the star? Is your shift claw adjusted? Quote
Atomic Monkey Posted November 16, 2014 Author Report Posted November 16, 2014 See the step in the frum behind the star? That's where I removed material to keep the lever from riding on the drum. Quote
SOUTHTHIRTY Posted November 16, 2014 Report Posted November 16, 2014 I see the step you made .. what part of the lever was dragging on it? Might want to check the plastic spacer that rides on the shift shaft right where it goes threw the case... see if there is any wear on it... thats wat holds the rod at the correct distance out Quote
hoppedupandcutdown Posted November 16, 2014 Report Posted November 16, 2014 Are you sure the roller is still the proper diameter? Quote
Atomic Monkey Posted November 16, 2014 Author Report Posted November 16, 2014 It was the actual lever for the shift detent roller that was hitting. It would deflect as the wheel rode up the star and ride the drum. Before I spun material off the drum, it had worn the pattern of the star into it. Because the detent lever (nothing to do with the shift lever) was hanging up on the drum, and the wheel didn't bottom in the star, it allowed the drum to freewheel back and forth a small distance. Before my last rebuild I had an issue with not always being able to upshift at high rpms. What I'm thinking is with the freeplay in the drum, the shift forks weren't in the right position and that maybe the engine load forced the forks and drum back to the gear I was in... mostly happened with 2-3 and 3-4. I can't remember exactly where on the drum the forks ride in those gears, but there was quite abit of work that I did to remove burrs and polish the drum to get the forks to ride through the gears with no snags. Essentually I'm trying to pinpoint where the upshift issue was coming from. There were many things done during the rebuild... Camatv did the Pro-Mod, there's a bearing from Mull on the detent, and I was in there tweeking on things too. Quote
trickedcarbine Posted November 16, 2014 Report Posted November 16, 2014 That did you tweak? There's a few variables, also a constant in your threads. Quote
Atomic Monkey Posted November 16, 2014 Author Report Posted November 16, 2014 Are you sure the roller is still the proper diameter?It is, Camatv mounted a bearing on a lever he had laying around. I compared it to the lever that was originally in the engine and didn't see any issues with either. Quote

Just making the forks ride though the drum... the burr removal, polishing the spots the forks hung on, and turning the material off the drum so the detent lever didn't ride up on it Quote
