Shift Rail

[ducati750]

My cub will pop out of third gear. If you hold it into third gear with even light pressure it will stay in. I pulled the top off the gearbox, and the fork is not bent and it goes fully into mesh. With the top off and pushing on the rail itself, it seems like it goes into the detent more firmly than to take it out of the detent. Sort of like the divit that is machined in the rail for the detent ball is more worn on the one side than the other. Is this a common problem? Is there a way to adjust the pressure on the detent ball? In order to remove the shift rails the tractor needs to be split does it not?

There have been post that the rails can be worked on with out splitting. I have never done it. They all seem to say watch out you don't lose the ball when it pops out. I am one of the experts will chime in and tell you how or where the info is.

You can "work" on the rails without splitting the tractor but they cannot be removed without splitting unless you cut them in two
There are two expansion plugs on the front of the transmission that have to be removed in order to remove the rails

Go to search on the top of the page. Put in transmission and forks. follow the one that says noise in transmission. Some where in it you will get the scoop. If I knew how to put it here for you I would have.

It sounds like the problem lise in the fork or the shifter it self. not the detent .

Thanks for your help. I too belive that the problem is that the rail is worn at the detent. I just got done spliting the tractor to replace the pilot bushing that was not installed by the guy I bought the tractor from. Guess I have to do it again.
