Could not remove freewheel...

Hi there, i've been meaning to make an account and a recent issue has kicked my bum into gear.

My bike has a 'Shimano MF-TZ20 6 Speed Multiple Freewheel'*. I received the bike as part of a school maintenance course. I'm trying to rekindle the skills we learnt. I've done my googling, but am not confident on whether I have understood and would like some clarification.

Firstly: Can someone confirm if I need a chain whip? Mislabelling has confused me and I just want confirmation.

I have the suitable sized removal tool. As advised by a video, I put the axle nut back on behind the removal tool finger tight. When turning in the anti clockwise direction (minus whip), I wasn't presented with the difficulty I expected, and I stopped immediately, concerned as to why it was too easy. The freewheel is still secure on there. I just tried again, for the sake of documenting what part was twisting. However, the tool will no longer move. I noticed that I cannot remove the axle nut. I can turn it, but it's difficult and it's not budging.

Does anyone have any advice before I concede defeat and take this to a bike shop? Additionally, have I basically condemned this entire wheel since none of this will now come off?

*The freewheel I have: http://www.jejamescycles.co.uk/shima...8t-id6831.html


Thank you.

do you have a vise to hold the axle ? if so put the axle into the vise , use a wrench to remove the nut to free the puller . if not ,you need to find a way to keep the axle from moving . try using a wrench to hold the other side of the axle .

Seems like it should loosen up if you turn the freewheel clockwise to move it back toward the hub.

No, you don't need a chain whip on a freewheel, unless you are removing individual cogs from the freewheel body. The freewheel is still secure because it has to turn several revolutions before it unthreads, which it cannot do until you back off the axle nut. If you are afreaid to turn it harder then turn the freewheel tool slightly clockwise while holding the nut. The reason you put on the tool finger tight is to allow enough give for the initial breaking free of the derailleur.

This is a prime example of the importance, on both the instructing and receiving end, of understanding the reason and effect of what you are doing, rather than just following a procedure.

Don't tell me what "should" be - either it is, it isn't, or do something about it.

If you think I'm being blunt take it as a compliment - if I thought you were too weak to handle the truth or a strong opinion I would not bother.

Please respect others by taking the time to post clearly so we can answer quickly. All lowercase and multiple typos makes for a hard read. Thanks!

If the freewheel is difficult, you may need to use a vise.

Sounds as though the freewheel is coming off normally, you need to remove the axle nut so the freewheel can continue to unscrew.
