How to remove a freewheel...

Postby [XAP]Bob » 12 Sep 2020, 6:56pm

When the freewheel has failed, and freely rotates in both directions?
A shortcut has to be a challenge, otherwise it would just be the way. No situation is so dire that panic cannot make it worse.
There are two kinds of people in this world: those can extrapolate from incomplete data.

What does the centre part look like? Does it take a Shimano splined tool or is it an old school type that takes a tool with two dogs?
The fact it rotates both ways is irrelevant as you could not have used a chain whip to remove it anyway.

a screw-on freewheel? ….as normal; it is not a requirement that the freewheel is in working order to be able to fit and use a remover on it.

If it's a screw-on freewheel, it must unscrew.

All freewheels have a tool to lock onto their boss, and with a spanner or a bench vice, can be turned anticlockwise to remove them.

Its knackered anyway, so destructive removal is in order. https://www.parktool.com/blog/repair-help/freewheel-destructive-removal
You don't need a pin spanner to remove the first bit, a hammer and nail/punch will do

A faulty ratchet mechanism makes no difference to removal of either a freewheel or a cassette from a freehub.

Has it really been that long since I’ve dealt with a freewheel that I’ve just forgotten... :oops: :oops:

Of course it must come off that way... else it would *undo* in use... I’m just being really dense.

I’ll have another look in the morning, but I think it’s a two prong doodad.

Once you have them stripped down to the last threaded bit, they sometimes undo without a fight. Regina ones certainly do. I think the other bits squeeze the threads or at least make the thing radially stiffer. A bit like drilling the head off a screw.
