Cougar sv diff and gearbox can anyone help
 

I've had the cougar sv for a few months now and race about everyother week, so far I have been through 4 diffs two gearboxes two spur gears, it is running a 78 26. Now first off I would think it is how they are built gearing etc but my mate is running the same and has had his the same amount of time and we build them together and he has had no problem can anyone think of any other reason the could be happening? I have also ask other people about the slipper and have had it checked and set up all ok on that front. I'm lost and thinking of just selling it now

I have the SV pro 2011. It came with an all metal drive train (except the spur and diff gear) no problems at all. Maybe you need to buy the metal gears?

That could help but it seems strange that my card does it more theny matesand we are set up the same like something else might be doing it

I'm using this in mine and never had a problem - http://www.m-k-racing.com/product_in...acturers_id=53

What case are you using, what layshaft, what outta gears and RW Spur?

Worst I've had is a the screw undo.

Hi mikey, it is the one Steve gave me so four screw casing and to be honest what ever was in it and the spares he gave me other then that I don't know and yes using the rw spur gear
