How to remove freewheel from unlaced hub?

I received this old hub (1940?) with 3 speed freewheel from France with the knowledge that it is going to be a challenge to remove the FW from the hub. Some of this was discussed in the ISO and for Trade thread (page 544) but I wanted to move it to its own thread.



If you have been successful in removing the FW without destroying it in this process what did you do?

Not done this, but I'd bore a hole in a 2x6, cut it in half and then put in 18 finishing nails into each half to line up with the hub spoke holes. Clamp it in a vice and remove the freewheel.

Basically all you are doing is replacing the spoke heads with nails.

Yes, good idea, it should be a separate thread. Here's what I wrote elsewhere, slightly edited:

Originally Posted by rhm View Post

The rim doesn't need to be big; 20" will do it, or whatever you have on hand. Weave the cable through a spoke hole on the rim through one on the flange, back to another hole on the rim, back to another hole on the flange, going through as many spoke holes in the flange as possible. When you get to the end of that cable, crimp a spoke nipple onto the free end of the cable to hold it. Then do the same thing with another cable. Use as many cables as you can fit, get the cables as tight as you can without undue effort. You don't have to make the cables very tight, since they'll tighten up when you apply pressure, but try to get all the cables about equally tight.

Do not use the non-drive side flange for this job.

This is definitely an option I'm considering. And if I'm not able to remove it with a FW tool I can disassemble the Freewheel. I don't even HAVE to remove the threaded core right?

I disassembled a wheel in order to get the hub, and while doing so decided to leave the freewheel attaché to the hub and to remove the spokes first. I was more than a little bit perturbed to realize what I had done. So I laced the non drive side of the hub (couldn't get spokes in on the drive side because freewheel was in the way) to the rim. Then I placed the hub in a vice and turned the rim hard & fast to break the seal. Then spun it right off.

Boy....I won't do that again.

I have seen that way done and the hub body twisted under the load of removal. Depends on if you need the hub shell I think.

Its really the easiest. Ive taken a bmx rim and some old spokes, cut the end off, bent it into a z with a vice and have the freewheel off in about 25 min.

Sounds good. Where do you live?

Another reason to hang on to old spokes.

An alloy hub? Thermo is your friend. Dunk the hub (not including the freewheel!) in liquid nitrogen. I bet that would do the trick.

@repechage - I, apparently, was very lucky.

That may weaken or even break the bond between the parts, but the problem is one of getting a firm grip on the hub without damaging it.

Go down to the co-op and buy some spokes and a cheap bmx rim.

I have an old 24" steel wheel from a kid size Schwinn Traveler boat anchor that I'm never going to use. Perfect for this purpose.

Not necessarily. I know that the two nudge hubs are notorious for slipping. Regina FWs can be a dog to remove.

In this case, I think, I want to be a spectator.

I removed one by disassembling the freewheel and removing the body. That gave me enough space to lace some spokes in the drive side and non-drive side into an old rim. I was then able to remove the freewheel.

I've never tried this but...

You could hold the freewheel tool in a vice, then jam the freewheel up against it, to hold it in place.
Then, you grip the hub with a strap wrench (oil filter removal tool) and use that to turn it.

With some luck, some brute force and ignorance (and a following wind), you should be able to get the freewheel off without too much damage or loss of life...

I started by saying that I hadn't tried this method. What I meant was that I've not tried it on a bicycle hub. This method has worked for me, on various bits of old car in the past...

Depends on how attached that freewheel is to the hub. If it's been there a long time, you're gonna have a hard time.

My prediction is that the labor will exceed the worth.

How to remove freewheel from unlaced hub?

Turns out the Suntour tool is way too small for this freewheel. The Cyclo compatible tool must look huge compared to the FW tools I'm familiar with.

What is the diameter? Shouldn't be too hard to make something that might work out of some flat stock. Any machinist friends?

Big ass pipe wrench or pair of channel locks might do it. But, if it doesn't break loose immediately I wouldn't force it.
