Monster Mill rotar issue

[Kinnick21]

so the free rotar on my monster mill mm3 will not consistently spin and is stuck 99% of the time, thus I have been unable to mill my grain. I saw many places where people said, 1) clean, 2) lubricant, and 3) disassemble and reassemble. I have done all of these and the problem persists. Any ideas?

Sounds like it's bound up. Have you tried checking the alignment of the end plates? Just thinking out loud, happy to disassemble mine if that helps.

This is a known issue with the MM3. The problem is that there are no rigid cross members to secure the 2 end plates and if they become too loose, the roller won't spin. This happens to me with approximately every 5th crush and it's getting really annoying. The only solution I've found is to remove the (usually full) grain hopper, loosen the screws that attach the MM3 to the mounting board, clean out any grain bits and then squeeze the top of the endplates so that the horizontal play of the rollers is tighter and then re-tighten the screws.


I read a post on some forum (don't recall which) where someone fabricated a metal widget that forced all rollers to always spin, it was brilliant. Maybe some very wide c-clamps to keep the top of the endplates secure would work, I haven't tried that yet though, it's just an idea. If anyone has a better way of robustly fixing this issue I'd love to hear it!

Good luck,
