HELP i can't get my cassets off

[JMAC]

I'm really pissed right now cause about every thing possible has gone wrong with my bike despate the thousands of dollars i put into it. The most recent problem is i just got new xt cassets so i wanted to take off my old crappy cassets which are on an almost new wheelset with an xt hub that i bought in october but i only rode them for 1-2 months. I broke my chain whip that i just bought and he other thing that is used to tighten and lossen the cassets.
So i went to my LBS and the guy their could get it off with all his strenght and he's way stronger than me. Than he put it in a huge vice while we both pulled as hard as possible on the chain whip it still hasn't budged what the hell do i do?

my only recommendation would be to get 2 of the strongest people you can find, give one the chainwhip to hold on to, and the other a breaker bar, huge ass wrench.

maybe WD-40 or penetrating oil?

btw, when you torque it down, you don't need to use too much force, as it is very unlikely that it will come lose.

In all the thousands that we've taken off, i've never come across one that one strong person couldn't take off, when doing it right with a vice. I was not that "strong" person, but watched:(

Anyway, If it's really that hard, maybe you could try the following (anyone feel free to chime in, i've never tried this on cassettes, but it may work)

What we usually do when a seatpost is stuck in a frame is we turn it upside down and pour antifreeze down the seattube to rest in there overnight. it's always worked; there is somekind of chemical reaction that weakens the rusts' hold on the seatpost/seattube. maybe try soaking the lockring (JUST the lockring, not the bearings) in antifreeze overnight and trying it again the next day????

Again, i've never tried it but it's worked on seatposts.

Good luck:thumb:

If you're saying goodbye to the old cassette forever, maybe a bit of brute force could help remove it. here's an idea, although it may damage the threads on the cassette body:
Get a cold chisel, and try to wedge it between the lockring and the small sprocket. I'm thinking that it's there that is causing all the friction.
Another option would be to tighten the vice on the actual sprockets, and then hold a big shifter on the lockring tool, and bash that shifter with a mallet. If worst comes to worst, you'll always have the option of using an angle grinder :)

Well i realize you don't need to tighten the cassets that much but i don't think my LBS realizes that they always tighten things like crasy wonse we get the cassets off i'm never letting them tighten anything on my bike.

i think your shop needs to purchase a torque wrench bro.

Have one person hold the chain whip and the other person stand on a big ass wrench.

I'm considering doing that the cassettes are no good anymore anyways i was also thinking of using a dremel with a cut off wheel to cut between the lockring and small cassette but the metal might be to strong.

[Rik]

Don't bother with the dremel, you might as well save the cutoff wheels and knaw at it with your teeth, that's about how good it'll be against hardened steel. A big grinder will do a much better job :)

can't you just take out the axel, bearlings, etc and take the freewheel body off with a 10 mm allen key and just get a new freewheel, they are only like Aussie$30 here so they should be pretty cheap in U.S

I don't can you?:confused:

[Rik]

Now now CTR, that's no fun at all, there's no use of power tools :p

Good idea though, I like your thinking, it'd be safer than hacking at the cassette.

Thanks for all the help i went to my LBS last night and the owner was in and he took it off no problem after it had been soaking in anti seize for 2 days.

Remind me not to let some of you :monkey:s anywhere near my bikes... :rolleyes:

Now, when you put the new cassette on there, GREASE the freakin' hub carrier like crazy before you slide on the cassette! Then, GREASE the threads on the lock ring before you thread it in! Then, go easy on the torque applied to the lock ring. You don't need a torque wrench, just give it a simple, not hard twist to set and tighten it. It will not come loose.

I already put them on i used loads of grease and i put a special thread anti seize on the lock ring so it won't seize and i didn't put to much power into tightening.

Torque torque! This beast needs more torque!

Actually only 22 ft/lbs of torqueis required. Oftentimes, I discard that small thin washer under the lockring, but using it in this application is recommended.
