I show how to pull the crankset off a bicycle without a puller tool. I have seen a lot of suggestions for removing bike crank arms without a crank puller, but most of them are bad ideas. I walk through each of these ideas and show some that will actually work without damaging the crankset or bottom bracket. I demonstrate successfully removing cranks without a crank puller in a couple different methods.
The bolts I showed were 7/16″ for the square taper cranks, and 3/8″ for the Octalink/ISIS (International Splined Interface Standard) cranks.
My recommendation is if you really care about your bicycle, buy the crank puller tool. They are usually relatively cheap. But some people live in places where simple tool like a crank puller would be extraordinarily expensive or hard to get. Like in deep rural areas of some countries. This video is for them.
