If I may share my own experience where at the last US Open I "stripped" about eleven 2nd Gear Spurs in 2 Days
. I had many persons offer suggestions. I even called and spoke with Ralph's pit guy and he talked about not going beyond a 4 teeth split etc..... Nothing worked.
Heck, I even asked the Kyosho guys to help, inlcuding Vincent Jackson and Joel Johnson. Everyone was willing, but nothing worked.
Guy would remember this.
Man I changed everything on that drive assembly.
Anyway, I say "stripped" with open and closed quotes, because that was not the problem. All along while I am taking the advice of others I was closely examining the gears and noticed to myself that they were not really stripping, but melting
. This was a result of counter weights I had in my clutch that was transfering heat from the flywheel through the weights and clutch shoes, then to the bell housing, pinions, and then to 2nd gear spur.
I finally decided to go with my gut feeling that was a heat problem and started to think of what would cause this. I simply replaced the shoes without weights and the problem went away. Ran the car again at another race and with a gear mesh that persons said at the US Open would not work but they were perfect! Gear mesh was never the problem.
My theory is that the Picco motor produces more heat (bi-product of alot of power
) in the crankcase and depending on the clutch configuration you have, this heat is being transfered to the 2nd gear spur and melting it.
It's funny now I think of it, because when I ran the taller gears it lasted longer, while persons were saying "you are going to tall and that's the cause".
Anyway, this is just my own personal humble experience that I hope helps in troubleshoot the problem. Just something else to think about.
