The ones currently causing me issues are actually from you, but I believe it is more of a user error on my end than anything on yours. There is a very slight lip or overhang on the caguamas which were causing the belts to rub against the wheel, so I put some shims inbetween the pulley and the wheel as a spacer.

It works but may have subsequently bent the pulley =/. I’m not sure though honestly what the issue is. @torqueboards have you set and ridden these pulleys with caguamas beofre? Have you ever experienced this issue before? Another user had the same issue and suggested the shim ring fix, just curious if others have experienced the same and what their solutions were to the issue.

@whaddys Not sure if you have the latest ones or the older ones. But the latest ones are easier to assemble as they have legs that line up.


If you have the older ones you have to align it straight and equally bolt down the bolt holes. Doing it incorrectly and you’ll most likely have issues similar to what you’re experiencing.

Also if the belt is rubbing against the wheel. You just need to re-position the motor pulley so the belt isn’t touching the wheel. Just move the motor pulley a bit and the belt alignment will change and will be less on the wheel. Of course, it’s better if your drive wheel pulley is lined up properly.

Oh. I like the new pulleys.

I was doing this but it caused the belt to hang slightly off the pulley which seemed suboptimal

@whaddys yeah, there’s ultimately not enough space for adjustment. It’s probably only about 2-3mm so you’d definitely have to fix the drive wheel first.
