My bros grind machine

He’s had it for a few months now and hasn’t bees able to use it with the exception of 2 or 3 throws, literally… The spacers keep grabbing on to the bearing and come off with it, then take a rediculous amount of effort to remove. This adversely effects the bearing by not allowing it to spin rendering the yoyo about as useful as trying to throw a rock on a string… I’ve tried repairing it with new bearings and spacers but it didn’t change anything… Any ideas?

i had this same problem, what you do is when the spacer comes off with bearing run a knife in the groove where the bearing meets the spacer. put the knife in that groove and put it on a table and push down hard.this should loosen the bearing from the spacer and let you pop it off.

Thanx!.. But how do I keep it from happening again?

take a file or some sand paper and file down the sides of the spacers a bit. not to much though. this will make em a bit looser. (i like it when people give me thankyous)

That sounds like a good idea… And as for a thank you, you got it!

cool hope this helps! :wink:

The bearing sticking on the spacers isn’t a problem. The inner race is what contacts the spacer. The outer race still spins. That’s how they are designed to work.


#8

It’s like they manage to get in too tight until the outer race starts rubbing against it… So maybe if it was a little looser it would solve the problem

spacers don’t have an outer edge that protrude up. The plastic is your problem. Most likely a mold issue. your best bet is to send it in for a new one.
