Freehub Removal troubles
Freehub removal troubles
I an trying to remove a freehub from a 20" wheel.
It's from a 2015-7 Dahon Mariner so it's a 7 speed.
I purchased a 11mm and 12mm alen keys and neither fit perfectly.
But the big problem is it won't break loose.
Yes I'm turning counter clockwise...
But I'm using so much torque that I've already bent 2 cheater bars.
The hex portion of the free hub is about 3/4-to an inch deep instead of at the surface.
I see no other grip or tool type to remove this freehub

Did you ever think it might be a good idea to include photos?

Ill be more direct, that was an apparently overly subtle way of saying Most of us dont know what the inside of your less than common part looks like. Why dont you upload a nice clear picture for us? Often when people do that we very quickly spot the problem, and are able to suggest a solution.

A bit of an oversight on my part.
Edit: the 12mm will fit, now i need a way to apply massive amounts of torque

The focal plane isnt exactly in the right spot, but it certainly looks like a hex. When you say the 12 mm doesnt fit perfectly, is it loose, or does it not go in?

First I would make extra sure that 12mm is the right size. Then try securing the correct allen wrench in a bench vise and lowering the freehub onto it. Grab the wheel in both hands and "drive the bus," turning the wheel counterclockwise. This works well with 700c wheels; hopefully the 20" wheel will give you enough leverage.

Not posting information is never helpful, if you need pictures you should post pictures if you need to tell us what you have tell us what you have. We see this too often with new members but with old members it just doesn't make sense. Sure sometimes cxwrench might seem a little brash but it is a forum on the internet you gotta have enough skin to handle people being honest even if it feels more on the negative side text really doesn't have emotion.

If the hub isnt on a wheel, get hold of a trashed rim and a half dozen spokes. Lace the hub onto the junk rim and proceed as above.

Yeah, my photography skills aren't exactly great.

Well, at least I know that I have the right idea, I just need more gorilla torque on this thing.
Thanks folks.

I finally did get a 12mm to fit.
Yeah, my photography skills aren't exactly great.
That's the delay right now. I do not have access to a vice. I may have a friend hold the wheel while I get a large breaker bar.

In lieu of a vice you can put the wheel against a wall, standing, and use the wrench/pipe in the direction that would roll the wheel into the wall. I do this all the time if someone is using the vice and I need to undo a lockring.

If you bought a cheap bench vise and mounted it to a long board, you could sit on one end of the board to twist off the freehub body...

Americans spell it "vise," while in other countries, it's "vice." I have no idea why.

Alright, an update.
I took the damn thing to a bike shop, put a 12mm into a vice, and tried to turn the wheel.
First horizontally, then vertically, with two fully grown men , one of them (me) channeling my extended annoyance, at the same time while the 12mm allen key was flexing the better part of 45 degrees.
Any more pressure and the allen key might have failed spectacularly and dangerously.
So, as much as I would like to give up, I'm not.
One of my friends likely has a 12mm socket and an impact wrench.
After that, I'm thinking blowtorch.
After that, thermite.
Maybe a tactical nuclear strike.

Assuming you get it off, be sure to apply anti-seize or grease to the threads. The freehub fixing bolt need not be installed with gorilla strength.
