From the pics, I noticed that the freewheel had been ground before I got my bike. so ,it is werd to me . How can I use freewheel remover ?
I am thinking to use King BMX hub instead of my front freewheel. but I have no idea on how to take off my ACS from my crank. Is it very hard to remove it ? I try to use park freewheel remove tool which I think does work on my front freewheel.
Does anyone have experience on this? give me some tips. what kind of tool I need it? or I should go to local bike store(BMX)which i should pay a lot on to get help?

hell no, dont go to a shop for this. Heres what you do, get a long threaded bolt(cheap seat guts work really well.). Take the crank arm off your bike and take the pedal off while youre at it. Slip the freewheel remover off the freewheel and then bolt it down with the long threaded bolt so that the remover has no chance of coming off the freewheel. Stick the square end of the freewheel remover in a vise. Get a long hollow pole, I used a clothes hanger from target, stick that over the end of the crank and pull, hard. Easiest way Ive found of getting a ffw crank off.

oh, yea, thanks digby, long arm can gain more torque. vice works better than wrench?? when u use vise stick then square end of the freewheel?

the freewheel tool goes into the vice. The square/hexagonal bit.

try to do it without heating it up first... heating up should be last resort.

What you are going to have to do ronan is a PITA...
Take your freewheel apart, so the teeth and everything are off of it- and all you see is the part that is attached to the crank...now take a dremmel tool or some kind of cutting tool and cut the freewheel down to the cranks threads- once you have this done you can take a chizel or a screwdriver and a hammer and hit in this crevace to turn your freewheel off (keep the crankarm in a vice).
Hard...annoying....but it works :)

I can see 4 joint point from my freewheel, so I should break that 4 points to take off my teeth and everything else which arent attached to the crank directly?

see the little holes? You take a freewheel tool and put it in there, and turn it and it will take your freewheel apart...ever had it come loose? This is how you tighten it, and loosen it- just loosen it till it all falls off.

but this freewheel has been ground by someone(maybe webcyclery). so it is hard to apply freewheel remover. that little hole cant hold the remover.
What I have done before with ground tabs is just make deeper grooves for the 4 prong tool with a dremel or a small drill bit, then just remove the freewheel as you would normally.

No, not the tabs- the holes...they can't be ground down; they are inside the freewheel.

The tabs are grown down so that you can have enough clearance for your BB.
his lockring has been welded by the looks of it, so he'll have a pretty hard time taking the lockring off with that tool.

It looks like I need to go to BMX store for help coz I dont have these kind of tools
They are going to look at you like you're crazy, with a freewheel on your crankarm lol. Just buy the tool and get the hell out of there.

I dont know who did this good job on my freewheel.

stick the freewheel into the vice and crush until it starts going oval. it will no longer freewheel, so just spin the crankarm out of it (still in the vise). I have to do this at the shop regularly on super cheap bmx freewheel that don't come with any tool interface

I really don't know how well this would work, but if you are interested in testing the limits of your isis crank ronan....maybe try it. Sounds dangerous to me.

does nothing to the $5 paper thin steel hubs, so I don't think that a thick aluminum ring would be affected. I would personally do that 100 times before I bring a dremel to the threads.

If you're gonna do it that way, I would rather fill it with jb weld or something.

Aluminum ring? I think we might be talking about different things?

wrong terminology........the "cylinder" part of the crank, onto which the freewheel threads

You would generally do this once the freewheel is disassembled. You want to grab the internal piece of the freewheel that threads on to the crank arm in the vice. You do have to tighten the vice enough to crush down the freewheel somewhat. If it slips out of the vice you can always tighten it down more, so go easy at first. A length of pipe over the crank arm will help with leverage.

Ronan just called me, lots of banging in the background. He said they already broke some wrenches and the vice :rofl: poor guy :( good luck ronan

no offense, Ronan, but maybe get someone more mechanically inclined/experienced than yourself to help ya?

I was in copesland'soprt BMX store. my friend break park vice(store owned).
we disassembled whole freewheel, and left internal part on crank. Tomorrow, I would go to my college engineering department to get more tools and stronger vice.
damn, I would never run any front freewheel anymore. it is very hard to take off.
Park Tools make a vice? hah! Ronan, i know why your vice broke. Put your entire weight into the leverage tool gradually, don't just smash force into it like you're hammering something. I've seen experienced (idiot, school dropout) mechanics do this a lot.

There not that bad if you don't grind off the tabs.

If u dont grind off the tabs, I dont think ACS works on my bike,although my BB is 128mm. For WI, I have no idea coz i never tired.

i ran a WI on a 128 mm bb on an echo pure and there was still plenty of room with the tabs still on. I dont think ACS ffws will work without the tabs ground off though.

Anyways, I finished my job today. and lookin for good deal on King rear hub..

I ran a 68x118 on my monty xlite mod...never even had to touch the tabs...

How did you do it if i may ask. I was wrong when i said its easy if the tabs are still on, mine is fucking harddddd.... i think im gonna cut it off like what andrew said. grrr stupid thing.
so anyways how did you do it ronan?
ronan_zj
01-19-2006, 09:51 PM
because I dont need my ACS freewheel, so I usa a hammer and a screwdriver to break my freewheel. after that, u may notice that only a inside part of ur freewheel is attached on ur crank.
go to find a vice, and a long pipe increasing ur lever arm.
ronan_zj
01-19-2006, 09:53 PM
if u do have tabs on ur freewheel, follow the steps by digby.

01-19-2006, 09:53 PM
so you put the broken up freewheel into the vice and then just used the leverage and your muscles :P to just get it off?

How did you get it off? I was trying to do this today, except I learned that I need a vice, To take off one of those things requires an unbelievable amount of force.

I throw away my freewheel. gonna get my King rear hub.
