Hi there

My freewheel recently jammed up almost completely (it will rotate if i clamp the spline into a vice and rotate the wheel), and I cant figure out exactly how to remove it - or whether it is possible without destroying the hub.
I've tried using a regular spanner but cannot get enough purchase on the nuts to loosen. I'm guessing I'd need to get hold of cone spanners to remove them effectively.

What I cant determine is how to remove the cone on the other side (side with the brake rotor), as the nut is sub flush. Any advice will be greatly appreciated.

Also important to note the thred on the axle seems to have worn. I'm not entirely sure what's happened here. I have converted my mtb to an ebike and so im assuming the high torque has had a real toll on this mechanism.

Cheers
Brendan

Bit more info or a pic would help. You can post one in your profile album.
You will need a cone spanner to get the axle out, once out, depending on the hub, you use a big allen key to remove the bearing race holding the free hub on. Shimano is 10mm from the drive side, most generic hubs are 11mm from the NDS (ie you need a long key to get in there) If it's shimano you can likely find a replacement, not shimano, you are probably out of luck and will need a new hub, unless you can figure out who made the hub (the branding is not necessarily the manufacturer) and then track down a parts catalog to get the freehub part number and then find a replacement online.

OP said it's a freewheel. 2nd post is how to remove a freehub. To remove a freewheel you need a freewheel removal socket and a chain whip. Both those tools can be improvised. I dont know how to include links but youtube has some great instructional videos. Especially the ones by park tool. I would watch the one on identifying freewheels and freehubs first so you know for sure what your working with.

Is it a FREEHUB or FREEWHEEL? Your title says wheel but your content says hub. They're two different things,OP.

OP states “brake rotor” so surely it has to be a Freehub and not Freewheel.

No chain whip required for a Freewheel. Whip required to remove a cassette from a Freehub.

Lots of people seem not to know what they are talking about, here, not just the OP. Proceed with caution.

See if you can remove a rubber boot on the non-drive side to access the cone locknut and then the cone to loosen the wheel bearings.

Concerning the worn axle...since you haven't disassembled the hub yet, I would assume it is the axle stub that protrudes pass the lock nuts and sits in the drop out?
are they quick release wheels?

Take pictures.

Hmmm...

First post and you did an e-bike conversion (mid-drive?) that has enough torque from the motor to jam the original freehub and strip the axle threads?

I need to find out what chain you are using.

Everything is normal though if you have the wheel in the bike and are pedaling forward? It's only when you stopped pedaling or pedaled backwards that something was amiss?
