Need help!! Keep blowing one way bearings!!

[fly-r-die]

I am sick and tired of replacing the one way bearing. I keep blowing them completely. Hell, this last bearing blew so bad that the rollers actually fell out of the races. And the kicker is I can't figure out why (except for the fact that the motor is super pinchy) I did try to replace the starter shaft with the advise from OFNA, that the starter shaft for the revo 3.3 would work but, they were wrong. The notch in the shaft that sits on the nipple of the piston rod is too small. Does anyone have any clues as to why I keep trashing the bearing? I keep looking at the Tiger Drive, but I don't know anything about them.

thanks

Matt
