    Default Changing the pinion gear on a stampede 4x4

    Anyone have any good instructions on how to change the pinion gear on a 4x4 stampede? I've seen some basic descriptions in other forums but i'm not even sure where to access the gear box. I checked the traxxas manual and there isn't much listed there which is surprising as they provide the optional gear with the kit. I also checked a few youtube vid's but can only see instructions for 2x4 vehicles.

    Also, what is the difference between the pinion gear and spur gear? When running lipo should I consider changing to steel gears?

    Thanks!

    Remove the gear cover. Remove the silver screw on the motor mount and disconnect the wires. Tilt the motor away from the driveshaft. Now the motor should come out and you should be able to change the pinion. Hope this helps.
    You think you know, but you have no idea.

    The pinion is small and metal and goes directly on the motor shaft. The spur is usually plastic/composite and takes power from the pinion to the rest of the drive train.

    I would stick with the metal pinion to plastic spur combo. In case something in the driveline binds it will eat up the spur and not the driveline. Also the plastic spur can take lipo abuse.

    +1 on that, much easier and cheaper to replace a spur gear than a driveshaft, diff, or even tranny gears.
