Re: VEXPro Ball Shifter Shaft Malfunction

After reassembly by tapping the shaft in with a hammer and what seemed like a solid fit, we put everything away for the night.

During today's meeting we drove the DT around for a few hours before the shaft came out a second time. We are wondering if anyone else has experienced a similar problem, it seems like our pit crew might have one area to keep a very close eye on this season.

Pictures below for reference.

We experienced the same thing yesterday, we finally got our drive train together and we were just driving around in our schools hallway playing around with the two speed and with in 15 minutes of driving it broke. Our plan is to support it on the end of the shaft to it is supported on both ends while containing it so it can slide out either
