On my RC-10 GT, I have already stripped 2 differential gears.My slipper clutch might be set to tight. But, anyway, I am thinking of using an aluminum diff gear this time.I already have an aluminum idler gear and I was wandering if this would cause any problem because of all the gears being aluminum.I am also wandering if any of you'all out there have a scanner. If so, would you please send me a copy of the instructions on how to assemble the differential on a new RC-10 GT. I would really appreciate it. I bought my truck off a friend as a RTR so I don't have any instructions at all on how to assemble this part of the truck.

If I'm not mistaken, I believe you can download the manual from AE's web site using Adobe. Their site address is rc10.com.

I figured out that I am not actually stripping out the gear itself, I am just stripping out the center of the gear that holds the ball bearings. What could cause this!! I will try AE's site for the instructions. Thanks!

If the diff gear looks melted then the diff adjustment was too loose or slipper too tight or both. When rebuilding the diff use all the parts in the diff rebuild kit and adjust the diff tight and back off 1/8 to 1/4 turn. The diff must not slip internally as the carbide diff balls will score the diff rings and the diff will feel gritty or in a severe case heat up and melt the gear. The slipper must always slip before the diff. After a fare amount of use the thrust washers under the slipper adjustment spring can loose their lubrication and cause the spring to turn the adjustment nut and tighten up the slipper each time it slips. This can cause the slipper clutch to become too tight with out you knowing and take out your diff. Hope this helps.

I've been having similar problems with my differential. I just went to an aluminum differential.

One thing to make sure and do is when you assemble the differential and install it into the transmission, make sure that the adjuster screw is on the same side as the slipper clutch. If not, your differential can loosen up on you when you start applying power to the wheels. I got this advice from the LHS today.

I'm guessing this is one reason why my differential has been coming loose on me. If anything I won't be melting differential gears anymore.
