My buddy had to replace a bearing on the lower quick drive pulley and now when he reinstalled it the belt keeps walking off the pulley, anybody have a suggestion on what’s up? Thinking that the bearing isn’t seated correctly but not sure.

Drive shaft or jack shaft bent or bearing issue, loose of bent quick drive pulley.

Remove the quick drive belt, check for any play in either shaft, then turn the track and secondary clutch and watch the pulleys for runout.

Don't overlook the obvious. Is the top sprocket which holds the belt on installed backwards? I'm not sure this is possible but crossed my mind.

It is possible to get one backwards... there is no belt guide since there is a shoulder on opposite sides of each pulley to keep the belt on. If it is walking off over one of those shoulders then I would say the belt may be shot, or the drive shaft put back in such a way that the shaft is out of parallel...

My first thought is a pulley installed backwards.... curious to hear what's going on.
