How do I change cranks on my cruiser?
#1
I need to know how to change the cranks, bearings and sprocket on my single speed cruiser. I also could use some info on exactly which tools I need to have for the job.
A video tutorial would be awesome. But basic instructions would help a lot.
Thanks in advance to anyone that can help

It depends on what type of crank you have - 1 piece or 3 piece. Can you post a picture?
3 piece is more common and used on almost all multi speed bikes. On a 1 piece crank, the two crank arms are made of a single piece that bends and goes through the frame. On a 3 piece, the arms are separate and bolted to an axle that goes through the frame.
Are you replacing everything for maintenance reasons or trying to change something?

It's a one piece crank common to old schwinn style cruisers. And yes I am replacing everything for maintenance reasons.

I'll add one-piece crank overhaul to the list of video requests!

Here's a quick overview:

(watch out that the illustrations are out of order)
Note that the left pedal and the left side nuts on the BB are reverse thread. Other than that, it's very straight forward.

Why do you want to change out your crank on that bicycle all you need to do is clean it up and maybe a new set of bearings and cups. The one piece crank are nice for a cruisers bike. I am building one but have took to long to get it done now with that pic of yours I want to finish it and I will try but I have to paint my old 10 speed bicycle first this spring after that who knows it may be another year or two. Give me a brake I'm getting old now days lol and I am trying to keep my wife happy as well thats a job all by its self :-)
My dad always told me a Sledge a matic can fix any thing.
