Stuck Drive Roller...Help!

[Esteban]

Good advice above.
Looking down on your very last pix, from the underside of the mount,,, it looks like the drive roller is at a slight angle ! This would mean that the opposing mounting holes for the drive roller are NOT aligned. This could cause binding & would be a manufacturer's defect.

How long have you had this friction drive? Did you buy it new or used?

As an absolute last resort, you could swap in the entire BMP or Staton driveline components to fix the problem. Motor mount holes look bigger than BMP/Staton, though.

I'm not an engineer, but the whole idea of a drive BOLT instead of an axle sounds cheesy. That drive bolt does not look to be a perfect fit for the bearings. Is that a sleeve I see between the drive bolt and the bearing's center?
