Subject: Dismal failure trying to loosen lockring
|
I'm trying to move the cassette to my new wheel. So I put the
chainwhip on the largest gear, and try to keep it from turning
counterclockwise. Then I put the lockring tool in and try to turn it
counterclockwise with a wrench. Right? Doesn't want to turn.
II put a tool into the lockring tool, and a hex wrench fits into that.
I still can't turn it.
I don't want to break anything so I haven't tried a sledgehammer.
Any advice greatly appreciated. Just turn harder?

Sounds like it is just stuck and/or tight. Be careful so keep the
chainwhip straight, so it doesn't slip off with unfortunate
consequences for your knuckles when they meet the spokes. Also make
sure the cassette tool is inerted fully and is seated well. Maybe use
the wheel's quick release to hold the cassette tool in place untli you
get it loose. Try a little penetrating oil too. I have used some gentle
taps from a mini sledge hammer on the wrench to get mine loose before.
Or use a long pipe slipped over the wrench for more leverage. Better to
use tools gently like a sledge or a pipe than to use your own brute
force. It is easy to slip when you are going at it with all you have.

Also, make sure you have the right cassette/lockring tool. I tried
using a Park Tool FR-1 (appropriate for Shimano/etc. freewheels)
when I should have been using an FR-5 (appropriate for modern
Shimano/etc. Cassette Lockrings). The spacing of the splines is the
same so it kinda worked, but it was difficult and things kept
slipping. Eventually I stripped the FR-1's splines. When I figured
out the error and started using the appropriate tool, everything
worked much better.

Yes, I see the potential for a hand damaging mishap. I'll wear gloves.
As I wrote to Mike, it's now been zapped with penetrating oil and I'm
waiting a bit.
The pipe idea is good. I don't know if I have a suitable pipe lying
around. But I've been using the wrench that came with the bike kit and
I certainly have better wrenches. If I can get that big plumber's
monkey wrench around it, the sheer weight should free it up.

I'm not going to try and decode what's gone on, but rather just give removal
instructions.
#1: The lockring is norma thread, meaning it loosens counter-clockwise
#2: The chain whip has to wrap around the cassette in a way that prevents it
from turning counterclockwise.
#3: If the lockring tool isn't engaged far enough, it will pull out on you.
You may need to hold it in place using the quick release, if it's long
enough.
#4: From previous discussions, I gather this wheel is OLD. The lockring
could be pretty nastily engaged, due to corrosion. You might try a
penetrating lubricant, and also tap it lightly with a hammer.
#5: Where does a hex wrench come into play?

Thanks, thats what I thought. I squirted it with vel Penetrating
Mystery Oil and will wait for a while.
As for the hex wrench, the lockring tool is designed so that a regular
wrench can turn it. But the outside of the lockring tool (where the
quick release comes out if it was long enough, mine isn't) is a half
inch square. An adapter in the kit fits nicely and converts that to a
smaller hex key hole. And, handily enough, there is an L shaped tool
that fits that perfectly.
I'll have a friend hold the chainwhip and I'll turn the lockring tool
with the wrench and L tool. Then, it will open. Hopefully. And perhaps
I'll be back with the next question.

If this wheel is old then it might be a freewheel and not a
cassette. That would be a nighte.

No, it's a cassette. It originally did have a freewheel (the screw on
type) but that was changed a few years ago.
