Dan Clark Posted September 8, 2005 Report Share Posted September 8, 2005 Hello people. I ride stock, so I know nothing about freewheels, but basically I bought an old T-Mag for my girlfriend for £80 which had been lying in a shed for 4 months, but it had a broken freewheel. My attempts failed at removing it, then my dad had a go with a scaffold pole on the end to no avail either. It is standard thread right? Anyway, how the feck do I get it off? I'm sure everyones had plenty of experience here. It's a crappy Shimano freewheel if anyones interested. Quote Link to comment Share on other sites More sharing options...
Lawnmowerman Posted September 8, 2005 Report Share Posted September 8, 2005 (edited) bolt the tool onto the arm using a wheel axle or something, then shove the arm in a vice, put an adjustable on with a few ft of extension and undo clockwise :) Edited September 8, 2005 by trialsboy560 Quote Link to comment Share on other sites More sharing options...
Bionic Balls Posted September 9, 2005 Report Share Posted September 9, 2005 Rather than using extreme leverage...."shocks" with a hammer/lump of wood seems to work best. You need a vice :) adam Quote Link to comment Share on other sites More sharing options...
Dan Clark Posted September 9, 2005 Author Report Share Posted September 9, 2005 Yeah, my dads a mechanic so vice's are no problem. So its left hand thread? so it undoes clockwise? That would be where we were going wrong. Quote Link to comment Share on other sites More sharing options...
Bionic Balls Posted September 9, 2005 Report Share Posted September 9, 2005 no...right hand thread! anticlockwise to loosen.. adam Quote Link to comment Share on other sites More sharing options...
Monkey Posted September 9, 2005 Report Share Posted September 9, 2005 (edited) It's a perfectly standard freewheel thread, clockwise to tighten, anticlockwise to loosen (with difficulty because pedalling along tightens it). With Claws freewheels the procedure is to unscrew the lockring if you haven't already (anticlockwise thread there), remove and throw away pawls, balls, springs and any other crap that might fall out. you are left with a - sort of - square shaped lump that can be clamped in a vice (tight enough to hold it in place, not so tight it crushes the crank) - then, with tenderness and finesse.... ....smack the crank hard with a rubber hammer several times at the pedal end. In the right direction. Pedalling backwards, if you imagine it's still on the bike. Hopefully it'll be something similar with Shimano freewheels.

Hopefully it'll be something similar with Shimano freewheels. ← It's loads easier just using a freewheel remover bolted to the crank arm/freewheel though. That way, you've still got a spare freewheel, and lockrings can be total bitches to remove sometimes. With my freewheel before, we had to actual dent, bend and fully rape the lockring to get it off. Anyway, a simple way of remembering how to take the freewheel off is to make sure you're turning it the the freewheel clicks (that's if you're doing it the bolted on remover way).

sir trial a lot Posted September 9, 2005 Report Share Posted September 9, 2005 boiling water is always a good one (Y) sit the freewheel part in a jug of boiling water for a few minutes and then do what the others say using shocks to remove it (Y) Quote Link to comment Share on other sites More sharing options...
Dan Clark Posted September 9, 2005 Author Report Share Posted September 9, 2005 Damn, this is gonna be hard to do. I'll give it another go I guess. I have a welding torch, would that help? Quote Link to comment Share on other sites More sharing options...
Exstionhead Posted September 9, 2005 Report Share Posted September 9, 2005 i find it easier to put the tool in a vice and just turn the wheel left, which means that there is no need for any bars or spanners to slip and you don't nack your threds (Y) Quote Link to comment Share on other sites More sharing options...

I hate taking htem off back wheel using the 'twist the wheel' method just 'cos of the horrific "CCRRREAAAAAKKKKKYYYYYOOOOOUUUUU'RREEEEEEBRREEEEAAAAAKIIIIINNNGGGGGGGMMEEEEEEEE" sound from your spokes/hub/rim...

shovel Posted September 9, 2005 Report Share Posted September 9, 2005 you say you have a welding torch, you could always try and weld a bar to the freewheel itself and then lever it off with that, would be very tricky though Quote Link to comment Share on other sites More sharing options...
Exstionhead Posted September 9, 2005 Report Share Posted September 9, 2005 well if the free is been put on with i bit of grease on the thread it come of no proble and u can do the same with freewheels on cranks (Y) Quote Link to comment Share on other sites More sharing options...
