Loose crank--what to do?

This reminds me of the old axiom for automobiles: The part that causes
the most accidents is the nut that holds the wheel.

But seriously folks...

Bruce, have you taken the crank off to inspect? If the nut is tight it
my have bottomed out and can't get any tighter. Perhaps the crank has
cracked or otherwise widenned.

Inspect the crank and the axle sides for wear. Perhaps rotating your
cranks will give you some temporary relief but it may be time to use
the services of Uni.Com.UK. Hopefully all you need is a new set of
cranks.

The other alternative is you can fly one of us out with one of your
other unis.

What kind of torker is it. If it is the lx then I could see the damage
happening but if it is a dx that probably shouldn't have happened.

We're riding today, are you going to show? We can all bring you new
cranks.

What Steve says is true, the nut (bolt) could be bottomed out. As I
remember, your Torker has those black painted aluminum cranks. The
square taper broached hole is probably worn beyond its useful life. I
would move back to the states where that is much less likely to happen.
Or buy new cranks from Roger.

I'll hop on the next flight to Seattle and join you for a ride through
the woods. If I leave a few hours ago I'll be there in time.

Failing that, if the nut is bottomed out (sounds plausible, given the
cranks ability to loosen when the nut is fully tightened) can I buy
myself some time by inserting a washer? Or is that too cheap a
solution?

Maybe I'll try stealing some cranks from my daughters' unicycles when
they aren't looking and see if that helps.

It would be nice if new cranks are all that is needed. Although, if the
unicycle were to suddenly have a terrible accident (oops--run over by a
double-decker bus, how did that happen?) then I'd have an excuse to buy
a replacement or two.

I'm sure that hockey is very hard on the cranks.

Not to over react, but perhaps 'this' (http://tinyurl.com/2ye3ee) is the
answer to your problem.

The ID of the washer would have to be large enough to allow the square
taper to pass through and the OD would have to be small enough to fit
into the crank. That would work but I don't think you'll find a washer
with that ID/OD ratio easily.

Finally somebody gets my subtext and gives me the advice that I want to
hear! Now I can do what I wanted to do and claim that I'm just
following independent advice.

Alternately I'll try Harper's advice from four years ago:

harper said:

As an alternative, remove both cranks, swap the cranks on the axle, turn
the seat around, and see what that does for you. Does the problem
follow the crank or the axle?

That will let me confirm whether new cranks will fix the problem. But
instead of turning the seat around I'll just ride backwards--very handy
when on defense.

for hockey and such, the koxx signature is looking pretty nice right
now...

The 2003 model Harper was much smarter than the 2007 model Harper. As
he suggested I swapped the cranks from left to right in an effort to
find out whether the cranks or the axle were the problem, and I found
it actually seems to have *solved* the problem. To play it safe I've
ordered replacement cranks, but I think I'm sorted.

I'm gonna bet that your crank is rounded out. Just go ahead and get a
new set of cranks. Any local bike shop will be able to inspect them
for you if you wish. Are you going to be using it for anything other
than hockey?

I got new cranks and it seems to be working well. I suspect that one
axle is slightly rounded (I kept playing hockey last week for a while
before realizing my crank was very loose) but things are holding
together much better now.

I switched from 150s to 125s. It's a bit of an adjustment, and I can't
start and stop quite as quickly, but I sure can go fast now on my 24".
