Re: Gear puller tool stinks!
If the threads in the gear are totally shot, try this; it will take 4 hands though, so a friend to help is necessary. Apply as much pulling force on the gear as you dare to using screwdrivers, pliers or whatever. While holding this pulling force against the gear steady and strong use a drift punch or piece of solid steel bar stock against the shaft and strike it with a hammer. Don't hit it too hard or you might upset the flywheel's true. The shock of the hammer blow will cause a vibration for a nanosecond or so and this should release the grip that the gear has on the shaft and the gear will pop off.
