Need a tutorial on Changing a gen 1 pinion gear

[xmodsunlimited]

Hey everyone!


Hope someone can rise from the ashes here and direct me some help!

I got a gen 1 stage 2 motor upgrade. and as we know it comes with 4. I wanted to use one for my gen 1 chassis, and the other 3 on evo. problem is. I have no idea how to remove the metal pinion gears from the Gen 1 motors! other than that.. soldering the wires is no prob. I can man handle it im sure, but I dont want to ruin the motor.

please help! thanks!!
