Just put a new spur gear in the beast, and after all of about 10 minutes runnings, the teeth on it are all slightly bent over. What's causing this? Is the clutchbell too tight, or too far from the spur, or could it be the clutchbell teeth being worn? I don't want to be going through spur gears on a daily basis. Thanks for the input.

yea that happened to me on my evader it is the clutch bell. it would chew up a spur in about 2 minutes on myn i just got a new bell and it dont chew em up n e more. also ur bell gears might look a little twisted if there not loosen off ur slipper and it should work ok....

Make sure to use the paper trick for aligning your gears. If it shreads a piece of notebook paper it's too tight. It should just get through without tearing up the paper. I keep a plastic spur in all my vehicles as a weak point just in case.
