    removing stubborn lockring

    i'm trying to remove the lockring from a 1988 shimano 600 hub. i want to use the wheel for a singlespeed so not so worried about the lockring as i have others.

    when i place the lockring tool into the lock ring, it "pops" out. it's as if there is no more than 1mm of depth for the lockring tool to sit. i took it to the LBS and they found the same issue. i've been through 2 quick release skewers.

    i sprayed WD-40 on it... i cursed it... i cursed its family... i turned to religion... i wished it was campagnolo... i don't know if the LBS tried these though.

    any suggestions? anyone cut a lockring off?

    my last resort will be "buy a singlespeed wheelset"...

    Are you sure it's a lock ring?

    The last cog on early 600 hubs screwed on instead of using a lockring. Try a chainwhip on the last log...

    VeloBase.com - Component: Shimano FH-6400, 600 Ultegra

    Or if it's an even earlier hub, it's a freewheel hub not a freehub...

    i was sure until you asked! i know the hub is the "tri-colour" 6400 series like link #1 and i thought i saw a "lockring" yet i'll check tomorrow. my grilfriend wouldn't let me bring any messy bike parts home. i've been working in my parent's garage, it felt so 1990s!

    i had the lockring tool "in" and the chainwhip on the last cog. the lockring tool popped out. do i need the lockring tool or just the chainwhip?

    Any chance of taking a pic of the "lockring" interface so we can see what's going on?

    Are the teeth on the cogs square or pointed? If they are square, you have a uniglide cassette. The last cog srews on.... If the teeth are more pointed, it's hyperglide and uses a lockring... Depending on the year of the hub, it could be either...

    hi Dave, photo above shows the cogs. the "lockring" has "hyperglide" stamped on it... so it's a lockring?

    Park Tool suggests using the quick release (just at first to start the process) as a way of holding the tool in place.

    thanks bikerjulio, i tried that and stripped two quick release nuts!

    when using the quick release the tool still pops out of the lockring/freewheel/cassette/hub/thing.

    Yep and that's a Hyperglide cassette too.....The good news is once you get the lockring off, it will be easy to convert to single speed.....

    Is your lockring tool the type that allows a wrench?

    yes it is.

    i had another similar aged hub with a similar aged hyperglide cassette lying around so i tried to take the lockring off that... that unlocked very easily. so i'm doing it all the "right way."...

    yet this hub has got the better of me... think i'll use this second hub yet find a 126mm axle, which i can't even use from the first hub as i can't get the lockring off!

    Try tightening it a little. It may break it loose.

    How about trying to put the cassette tool in a vice and then placing the hub down onto it, get more weight forced down so it won't pop out...

    it's free!

    so, after two broken quick release skewer nuts, a rounded lockring tool and lots of swearing and cursing the cassette is free!

    took it to the friendly LBS for one last attmept... they put it in the vice, no luck. the vice moved more than the lock ring.

    so, i headed to the not so LBS to purchase some single speed wheels... the guy there decided he'd have a crack... with me holding the chain whip, and he leveraging on the biggest m!#$%^& f!#$%^&* wrench i have ever seen the cassette shifted a little! felt bad as i went there to buy some wheels, he, for now, cost himself a sale.

    yet, the freehub looks like this... does this mean it shouldn't have had a lockring installed? can i this hub as a singlespeed with a cog, spacers and a lockring?

    It will work fine as a single speed...Those hubs were "transition" hubs when Shimano went from Uniglide to Hyperglide... It's threaded on both the inside and outside to accept either cassette...Use your SS cog, spacers and lockring...No problem....
