Default Re: How do I change one piece crank to 3 piece crank?

This past spring I picked up an extra wide three piece crank to replace a one piece on an old Huffy frame in an attempt to make room for a pull start engine. I discovered that the diameter of the frame opening where the bearings fit and the crank goes through was different. As I recall the one piece was a good deal bigger. I gave up on that approach and installed a one piece short armed crank from a 20" bike. I still have that three piece wide one, but haven't found a use for it yet since I pretty much work with old cruisers. I don't know if there is some kind of reducer so that a three piece would fit or if there are different sized three piece cranks, but would like to know.
Someday when I grow up I will probably lose interest in toys with wheels, but until then...
