Need help MT won't move!!!

[XDEEDUBBX]

Hey guys, I seem to have run into some problem with my MT. Everything start up fine but when I throttle the truck it doesn't move very far but the motor revs freely. If I throttle the motor it'll move a few inches and rev freely but it's not going anywhere. I'll post up a video tomorrow morning but any suggestions will help. Thanks

Check your gear side?

the gear mesh looks good. When the motor is turned off and i push the truck forward and backwards the mesh seems ok.

Check the set screws on your drive cups.

The MT has pins that hold the gear mounts, if you have the 4pin style gears. They are behind the gears. You might have lost or broke one. This would allow a shaft to spin freely inside a gear.

Check the set screws on your drive cups.

Like Cordy said... it could be one of your cups have a loose set screw resulting in no power to wheels. Check all your cup to see if they don't spin freely. Check if clutch is engaging?

are the drive cups connected to the dog bones?

Yes they are and if they are working fine then check the pin behind the gears as rc dad stated.

Check all of your dog bone pins, as well.

If all that everybody has said is OK, check the diff cups. When I broke mine it would move a lil then just rev as ur saying. Hope that helps.

Looks like your brakes are dragging. Your throttle/brake linkages might need to be adjusted, or you need to adjust the brake screws.

Here's a visual...

Thanks for posting that pic Deluge. I was looking at those screws today but never thought for a minute what they were for....

Is there a better diagram for the Rampage besides the one available at Redcat's site? Even at full zoom, it leaves a lot to be desired for....

My MT came with no CD. Was that only available on the first version?
