So i was rideing down the road and i head a boom! And then my track locked up so i looked and my whole drive shaft got pushed out of the pto side. I went home tore it all apart and it was the pto side drive shaft bearing that went out. I took the chain case cover off and the chain was off the botom gear and the gear tilted in and make groves on the cover. I am sure the shafts not bent and i replaced all the bearings and flange plates. I put the chain on the gear and it seem tight! And the chain tentioner isnt even tight yet. Could it be that the new sping tentioner is brand new and its more tight because its not warn out?
