savage flux drive gear problem

[danielc79]

ok, so i'm stripping out drive gears and i don't know why.
the first time it looked like something was not lined up right, one side was stripped and broke off (the teeth were missing) the other side they were stripped but still there. they were very pointy almost wore away completely.

my 2nd one, i put on about a month ago, is gone all the way around the center. there is not much play in the transmission, i tried it when i changed it the first time. everythin seemed to be smooth. i also read that there is no need to put any kind of lube in the transmission, as it does not come with any stock. This is kind of rediculous though to have to keep changing this part.

is there any kind of upgrade available for this gear? i found an aluminum and the stock metal one, however i think it would be bad to upgrade to aluminum, wouldn't that be softer and more easily stripped?

if you have any ideas let me know, this was my first problem ever with the tranny, what can i do to make it my last problem with it?
