Get rid of those eccenrtic bearings 6 chain attex conversion. I will be doing a 2 piece split shaft collar replacement with pics. I have tried everything else to keep the axle in place. This is micmac conversion for max adapted to a 6 chain attex. i have tried the eccentric collars on the inside of axle do not work with bruiser so i purchased the bearing with 2 set screws in the inside bearing loctited in still moon walking. So i got some 2 piece split shaft wich are on the way. The only difference will be from micmac is you can not do the left middle on the inside because the sprocket itself sets flush against the bearing on the inside. If this does not work the engine will come out next and a 13 horsepower power max will be installed tired of working on it i am tired of frame chew
