    How to: replace shift shaft?

    wondering how easy it is to replace the shaft that the shifter bolt to? Mine split apart in the recessed area?

    I assume the right hand side case needs to come off along with the clutch basket. What else is involved or do I have it all wrong?

    Thanks

    Good luck my friend.....I have been puttting mine off since the Steele Creek GNCC. I got a new shifter after that race. It lasted about 2 races. I used JB Weld, lasted 1 race. Then I finally welded the shifter to the shaft. Now time to break down and split the cases and replace the shaft before the start of next season......which is only 2 months away.

    Let us know how everything goes...if you end up doing it yourself or sending it to someone. I am going to send mine to Moto-X-Perts so they can replace it.

    just to make sure there is no confusion...I do mean on a 2001 400ex. I know my signature lists a 450r.

    The 400ex is my trail quad.

    I think I will opt for welding too until I have to tear the motor down.

    Thanks,

    I am sponsored through them. I am just sending them the bottom end. They are going to do the ISF process on the gears also through CV4. They paid for shipping last time.

    Question:

    Can you just remove the LEFT case including the stator and starter ?

    Or do you HAVE to do both sides (including the clutch) to replace the shifter shaft ?

    They show in the manual that you seperate the Left case from the right.....but if you're not removing the Transmission......why can't you leave the Clutch side alone ???

    Anyone ever try this ? Or am I looking at a complete dissassembly ?

    Thanks

    You don't just remove one side of the case it splits and all the inners must be removed in order to get it to split. Its the same as what you would do to replace a crank for the most part, except you are replacing the shift shaft...

    I understand that part......It's just that in the HONDA Service manual it shows the right side (clutch side) being removed from the Left side Stator side)

    So If I take the Clutch and gears out.....I can seperate the case halves WITHOUT removing the flywheel.



    I just hate taking things apart or dissassembling things that aren't neccesary.
