ATI balancer?
 

I have a ati damper. I was wondering if anyone knows if the weight can be changed on these from 50oz to 28oz. I don't see anything on their web site about it. But if it's rebuildable, I would think it's changeable? I am getting a 347 scat set up that's 28oz. The old(new)motor only lasted 13 pulls and came home wounded. I don't want to have to buy a new $350 balancer.
