Since many of you have been asking for information on this matter and I wouldn't be a reliable source to provide it, I have found a couple of great sites that can help you out. The first one is a step by step total rebuild from Steve Litt. Extremely well detailed and with lots of photographs. You can find the article here: http://www.troubleshooters.com/bicycles/1speed/1speed_overhaul.htm
The second valuable resource can be found at ratrodbikes.com's how-to section in the discussion forum. Member new_dharma and others have posted some diagrams of many hubs and this could also help you out. The information can be found here: http://ratrodbikes.com/forum/viewtopic.php?f=3&t=1162
There is one thing that I can contribute in your quest to overhaul a single speed or any other coaster brake hub:
- Prepare a clean working surface, no piles of little knick knacks that can be confused with tiny hub parts.
- Use a rag to cover your working surface that will prevent parts to bounce off into the 5th dimension of your workshop, never to be seen again until just before you move after selling the house.
- If you have a camera, be smart and take pictures as you dismantle(This one applies to anything you ever decide to take apart for the first time, trust me.).
These 3 little simple steps will save you a lot of headaches and should keep your money out of the cursing jar! Don't rush things and you'll be fine.
Until I find a hub to rebuild and find the time to try Steve Litt's steps, this is the best I can do for you. Good luck to you all.
Til next time ride safe and Godspeed.
