If you have a 3 piece crank [where the arms are bolted on sperately] the only way to remove them and prevent damaging them, is with a crank removal tool.
Remove the fastener [bolt] that is holding crank arms to the (spindle). Then, use this crank arm removal tool - like a gear puller - to remove the arm.
This tool works with the [WHIP TOOL BELOW] to remove "drop on" type cassettes where the outer most ring srews off and the cassette drops onto a freewheel - which stays attached to the hub... This would be considered a newer style Cassette style / freewheel.
The older style freewheels screw off completely in one piece using the tool BELOW [just below the whip tool] on this page.
This tool is easy to use. Just drop the long end of the chain onto one of the larger gears on your cog / freewheel. Then use it like a lever to keep the gear cluster from spinning while you use the Cassette Removal Tool to screw off the outer ring in order to remove the cassette / freewheel.
This Freewheel tool fits most of the old style "screw" off multi-speed cog / gear cluster units. Line up splines and drop into hub. Then use a [large] crescent wrench or vice to remove freewheel. Freewheels are Standard fine threads and screw off counter clockwise direction.
There are many other style freewheel removal tools but the ones displayed on this page are the most used... You should be able to tell what type you have with a close inspection of your freewheel.
These [thin] wrenches allow for breaking loose - axle/cone fittings. This way you can remove, clean, re-pack and properly readjust wheel bearings. Cleaning / heavily greasing / properly adjusting wheel axle bearings very important! when motorizing bicycles.
This tool is designed to allow you to install a star nut fitting into a fork, fork legs, etc. without damaging internal threads...
Tip: Star nuts are hard to remove. So, if a star nut is damaged and already inside fork tube, etc. Most times you can just drive it down - out of the way with a large phillips screw driver and hammer. Then, just install a new star nut in its place.
