Hey everyone i have been having problems with my trans in my 03 660. At first i thought it was a combination of a worn out sproket and a bad chain, well i changed all of that and still no luck in 2nd gear ( the only place i am realy haveing the biggest problem with. Also when i changed my clutches i found a short allen head bolt just laying in the bottom of the case. I finally bite the bullet and tore the motor down thinking it was a stripped gear in the tranny, well today i got it all apart and all the gears look alright. All of the bearings looked good and had no movemen, except on the shift drum. I noticed it had a good bit of movement up and down on the bearing, and had a couple nicks on it. So my question is could that casue my issue in 2nd, because it almost acts like its not all the way in gear. and right now i am at a loss because everything seems fine except that, and i was wanting to ask before i just replaced it and have to get it all back together before i can find out if that was the problem. Any help would be much appriciated.
