if you dont want to spend the 30 bux on the clutch holding tool and you have an old set of fibers/steels laying around that are burned up or something you can make one. get one fiber and one steel, drill a hole through each of them and bolt them together (2 will do just fine) you can use this to keep the inner hub from spinning, but the motor will still spin so you still have to do something about that. i've made one and never had any problems with it.
