Freewheel Stuck On Hub

I've installed a BMX freewheel (19t, the big Shimano kind) on my Surly 1x1 hub but the removal mounts broke as I was trying to remove it. Unlike other freewheels that I've seen, this one uses a removal two with only two mounts (example picture of a hub with 4 mounts for removal here, mine only has two).

As I was trying to remove the freewheel, one of the mounts broke off; now I'm stuck with a freewheel on my hub, leaving me unable to adjust my cones. The hub also has two spanner-holes, but I can't imagine ever getting off a tight freewheel with just a pair of spanners.

Does anyone have any suggestions?

Take a flat end punch and a heavy hammer to the remaining tab. Hammer in a direction tangent to the circumference of the FW body so it spins CCW.

Edit:

So I gave it a whirl with a hammer and press, but still no luck. Its a bit awkward to attempt, but no luck after 10 minutes of whacking away.

ARe you right handed? If so, I've never failed to take off a freewheel. Includes all junky bikes I've worked on.
Use a visegrip to hold the freewheel in place
Put the quick release skwer to hold all in place
Hold the wheel with your left hand
The wheel should be facing straight in front of you with the freewheel on your right hand side
Vise grip handle should be going towards your right foot
Lift right leg (wear good shoes or boots)
Bang on the vise grip with a SWIFT downward motion on the vise grip
Remove freewheel
Pat yourself on the back
Have a beer

Its the QUICK FORCE that will remove it, so make sure you hit it once and very, very hard.

I had a freewheel stuck on so tight, I had tried everything, was using a mallet against my wrench to try and pound this thing off.

Did a search, put on my shoes and kicked that freewheel off on the 1st try. Thanks for the tip!

I had spent about an hour trying to pound my freewheel off too until I found this thread and kicked it off in two seconds. Awesome.

i can't picture what is going on here...are you smashing the vice grip handle into the top of your shoe? the side? the toe? why does a force perpendicular to the threading work to remove it?

+1. I don't get it.

You should post a video with closeups.

I cant figure whats going on with the vice grips

I ussualy hammer a drift or screwdriver against the circular holes in the opposite direction from pedaling. this moves the freewheel most times

some cheap BMX freewheels have no tool slots to remove it with. so got to use a drift on them

This worked for me, was awesome, so glad I found it. I did have the vise-grip on the 4-pronged remover which was in the freewheel, though, rather than have the vice-grip directly on the freewheel.

STOMPED the pliers, they spun around the threads three times, was very gratifying.

The wheel is aligned as if in a bike being straddled, the vice grip aligned in the plane of the wheel. But instead of trying to turn the grip by hands you stomp on the tool.

tear it apart, ball bearings all come out and the freewheel comes apart, when the outer ring is removed.

then you stick the core in a big well anchored bench vise, and unwind the wheel.

I will have to try this next; the vice-grip stomp worked for a frozen-on freewheel that had never actually been engaged (far side of flipflop hub). This one that I have been using for just a month or so is mortally locked on. Could be a lesson in being much more scrupulous in cleaning the threads before greasing/installing, next time...

Single speed freewheel bodies often aren't all that strong. Put the freewheel in a vise and crank down (wear eye protection because sometimes parts chip off and go flying) You should be able to ovalize the sprocket and outer body enough to jam it, and can now turn the wheel to the left, like a truck steering wheel to remove the wheel from the freewheel.

Normally I wouldn't have you destroy it this way, but once the removal prongs are damaged, you wouldn't want to reuse it anyway.

Yep, tear it apart and buy a new one. This time buy a better quality one with the 4 slots for a removal tool, which will give more bearing surface and allow everything to come apart easier.

Too bad they are not splined like freewheels, those come off normally without distorting. Well it took about 60lbs of pressure on a 10" wrench to get the freewheel off my girlfriends bike (Trek 7100 wsd stock wheels). I applied grease to the threads as they were DRY from the factory...aluminum + steel = needs grease! Her bearings were also not very well greased, on a 3 year old bike, but that is for a different thread.

A new Shimano bmx freewheel is $20. Cheap.
