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.

hi .. well I have ordered a one piece crank, and now realize I have a 3-piece .. is there any way to replace a 3-piece with a one piece?? I doubt it ..

   
   

The crankset in the pictures is a one piece.
