My belt keeps needing to be adjusted ,just replaced for second time from cogs broke off first time probably my fault ( hard launch hole shots). But second time I had to adjust from being loose couple times then I just checked before trip found loose with broken cogs again it can't keep stretching can it

 

Broken off cogs? Were these Cogswell Cogs by any chance?

 

i'm gonna ask astro what he thinks. all kidding aside maybe you have a bad wheel bearing letting it loosen up. if it's torqued correctly do'n know how or why this would happen.
