Hi!

I have been overhauling my Yamoto 250's gearbox, due to it slipping/crunching the gears when the load gets high. Problem was with the directional gear, as the forward bearing wandered around about 2mm. shimmed that up good, and its nice and tight now.

I also disasembled the main and secondary clutch assembly to check for wear, but they seemed alright, so I figured i would clean them up and put them right back in. Here is where I encountered my problem though, as i didn't note which way the lock-up bearing on the main clutch should go. Should it lock clockwise or counterclockwise? I'm thinking clockwise, so it locks the same way as the vario clutch.. Any hints?

Could also use some pointers on how to adjust the gears!

Thanks in advance!
Yours

Resolved this myself, the bearing i was talking about is of course the engine break, and needs to sit so that it locks the opposite direction from the vario clutch!

Could still use some pointers on adjusting the gears on this "badboy"
