View Full Version : bert ball spline tail shaft broke!

over the off season i rebuilt the the ball spline on my bert cuz it had some play in it. after the rebuild it tightend it up and worked fine till about 6 or 7 races in the season... the whole tailshaft housing exploded. what could cause this? did the balls wear out enough to make enough vibration to do this(this is my guess)... or should i be lookin in another area? ima replace the whole tranny just in case of bent shafts or bad bearings and get the driveshaft checked for straitness and balance. opinions would help... thanks

Is your output shaft and ball bearing retainer survive? If so, do you want to sell them? I broke my output shaft a few races ago when both shocks failed and allowed my rear to move more than usual and hammer the end of my tailshaft.
