Worn Shifting Dogs

Last year we were using the Generation 1 Technocats shifter that had the separate dogs mates attached to the gears. In practice we had assembled the transmission too narrow and while at full speed it shifter and ended up in high and low immediately locking up the transmission and shearing off the three screws that held the dog mate onto the gear. We took it apart and welded the gear to the dog mate and it worked for a while longer until it was assembled yet again narrow. This time, under a full power shift it again locked up the transmission but the shock went through it and sheared off the motor pinion on the bosch. We put a new motor in and used it the entire season and post season with no signs of wear on the dog or dog mates. With generation 2 having the dog mate milled into the steel gear it looks to be even stronger. My 'non- expert' opinion is that it is oversized for the loads that are being applied to it by our motors in the kit and for its limited use in a FIRST season it works spectacularly.
