Freewheel axle shaft question????
 
I found a very dirty, dusty Schwinn 5 speed Cruiser that I bought very cheap. Got it home and started taking apart and cleaning it.
It is a Schwinn Cruiser with a date code on the front badge dated 2766. Also on the back is a sticker that says Giant and has the same number. Looking at the info I have found it could be a '66 or '76.
My question is on the freewheel shaft, the threads are buggered up some. Looks like it might have been rode with the mounting nuts loose sometimes. They were tight when I removed the wheel. I'm not sure the thread size but I think they are 3/8" x 24 tpi. It is 6 1/2" long.
I have another shaft that came off a Huffy mtb that is the same size and length but when I took one of the nuts from the Cruiser and threaded it on the mtb shaft, it seemed to be just a little sloppy. Not much but a little.
I'm not sure if the thread pitch is the same but another idea would be to use all the bearing cups that go onto the shaft from the mtb and just use it that way. Both bikes have the same bearings so that wouldn't be a problem.
Then again I could just buy one off Ebay or local bike shop.
I redid the front wheel yesterday and did a good cleaning. The chrome will allmost blind you it shines so much in the sunshine. The more I clean and polish it, the more excited I get about how it will look when finished.

Thanks
Richard

That diameter axle is available with 24 and 26 threads per inch, and the nuts and cones do not mix. A new axle should be readily available locally or on line. Metric equivalent is 9.5mm.

Switching cones can be a little tricky. Metal dust seals might interfere (though they can usually be removed), and total distance between locknuts might change. That can often be fixed with axle spacers or washers. Worst case would be resetting the dropout spacing on the frame.

The Schwinn nuts may be too worn for accurate gauging. Your local shop will have a good gauge.

To avoid confusion please refer to the links below for bike terminology. The first link shows the names for internal parts of a hub (as well as the entire hub overhaul procedure) the second is an overall view of the parts of a bicycle.

Also, your use of non-standard terms indicate that you might be working on the bike without accurate guidance. I would suggest you check at Park Tool Repair Help. Go there before you rely on YouTube videos, which are not always complete or even accurate. As noted you can't at all count on the cones (not bearing cups) being compatible. It's more likely they are not. If you have enough axle length the fix may be as simple as putting extra washer width on the right side or shifting the axle and then sawing off the excess on the left end. Make sure the damaged part is actually where the nut ends up, rather than where the dropout sits on the axle. In any case I would caution against jumping into ordering parts online. Check with your local shops - both Cyclewright and Overmountain have multiple good reviews.

Thanks for the info.
I'll check with CycleWright since I have dealt with them before. I'm sure they can order the part I need.

OK, but keep in mind that you may not even need a different axle, as I noted above. Also, although the axle should be no problem if you do need one the cones may be more difficult, as even a dealer can't just order a "cone for a 5 speed Schwinn cruiser." Finally, if you tackle this yourself you will need some tools, although I would just have the bike shop pop off the freewheel, so you would only need a cone wrench and proper instructions, which are best done at: Park Tool Repair Help
