Rotational play in countershaft
Permalink  
 

Long time since I've been around here!

Back on the TTR and have been noticing some odd gearbox behavior. Specifically, un-cooperative shifting gears when idling at standstill. Doesn't like going from Neutral to 1st or 2nd, or indeed shifting down from any higher gears if I coast to a standstill. Lever moves partially but then just feels like it hits a 'block'. No grinding or anything. Just wont shift. If I drag the clutch ever so slightly, however, it pops in. Once moving, all is well.

Have incidentally noticed my countershaft seems to have a LOT of rotational free play. About 2 teeths worth, when in gear. Wondering if this may be linked?

The gearbox is old. VERY old. Almost 20 years and about 50 000 ks.


Thoughts?

Thanks!

its normal to have a fair amount of free play in the counter shaft sprocket . 50,000 ks isn't that high for a gear box  .

my first thought was a dragging clutch but you description makes it sound like it could be something else having recently put a gear box together they are pretty simple , may be worth waiting to see if anyone else has some ideas .

Wonder if your gear change pin is damaged. See here for pics:
