can't remove freewheel

[izeman]

i installed a former 7(?)speed freewheel on my hs3540.
former 7speed, because, it took off all gears, but the smallest one to make it a single speed.
screwed it one, but now i have to remove it, but can't get it off. i bought a shimano remover, like this on

but i can't remove it. i just doesn't grip. the inside of the freewheel looks (somehow) like that:

what tool do i need to remove it? thanks!

you need a freewheel tool with an enlarged center to fit over the axle.

thanks. the picture i posted was an example. i removed the handle and made a bigger hole with a plasma cutter. so it does fit over the axle. but still it doesn't grip the 3 little noses. i can't say what it looks like exactly, as the motor is mounted on the bike right now.
do those freewheels looks different? i mean: do some of them have more/different noses inside?

here you can see that the removal tool has a 1:1 match between grooves and noses corresponding to the freewheel.
no like mine

it looks like this:

website selling those says: may require deep spline, thin wall freewheel tool for removal
whatever this means

I did this recently. Tried using PB Blaster and large wrench with freewheel tool, still couldn't get it off. Had to go buy an impact wrench.

maybe they want to tell you to buy such a tool for removing the freewheel.

das

dürft' auch passen, und das gibts hier

nearly matches your nick

btw, when i had to remove the freewheel from the magic pie, i took off the side cover of the motor with the freewheel.
the axle was no longer in the way.
then cut a piece of sheet metal to fit into the slots and you can screw it off.

(only if you're in a hurry, i was, it happened on a weekend.)

Yes. Freewheels use different tools / splines to the cassetts and different manufacturer's used different splines also. http://www.parktool.com/blog/repair-help/cassette-and-freewheel-removal

The tools made for 1/2" square drive are generally big enough to fit over a motor axle, unlike most tools that are designed for use with a wrench, which tend to have a smaller hole for the std bicycle axle.
