Crank Removal Problems

When i removed mine, I had the exact same problem. I found out that if
I put the pinch bolt back in, with only a slight amount of pressure,
then it came out just fine by hand. The other one didn't work as well,
so I found a long bolt and put it where the hub bolt goes. I tightened
it slightly, then I held the crank and hit the end of the bolt on some
heavy, solid object. Crank came off no problem, with no scratches from
any crank puller or anything.

Hey Seamus, I have the same problem with my left crank whenever I take
it off. What I do ( and it's not the best thing to do but it works) is
to take a flathead screwdriver, put it in the gap where the pinch bolt
goes, and apply very slight pressure and pull the crank as hard as you
can. Works every time. The only thing Im not sure of is whether it has
any long term effects. I think not, and if the gap increased, when the
pinch bolt goes back through and it's tight it would prevent any
wiggle. Next time I'll probably just buy a crank puller though...

I don't know what else to try but if anybody has any advice on getting
them off I would greatly appreciate it.

the solution?
two KH 24's, one for you and one for me.

cheers

(as far as real advice, using a screwdriver to open it up more is a
good idea, so long as you're careful. crank pullers are designed for
bicycle cranks and i'd imagine it would be difficult to find one that
works on your uni...
kyle and i encountered this same problem working on my onza and in the
end we just managed it through sheer brute strength, so no help there,
sorry...)

Yeah, you want to be really careful you don't bend the metal by giving
it too much force. Then your screwed.

A flat screwdriver in the pinchbolt gap will help loosen the crank. You
can also use a bearing puller to remove the crank. Unicycle.com sells
the 'Evercraft bearing puller '
(http://www.unicycle.com/shopping/shopexd.asp?id=419)that will do the
job. Auto parts stores also have a variety of similar pullers that are
used to remove pulleys and gears for auto repair.

Here's a thread with pictures of how to 'use the Evercraft bearing
puller to remove a Profile crank'
(http://www.unicyclist.com/forums/showthread.php?t=18640). Same
principle for removing a Qu-ax crank.

A bearing puller is something you'll need eventually anyways if you
have a unicycle with press on bearings (a Coker, freestyle unicycle,
etc.). So you'll eventually need the tool anyways.

When you put the cranks back on use some waterproof grease or
anti-seize on the splines so the cranks will be easier to remove next
time.

I tried the screwdriver thing, but with a prybar, to no avail. I don't
know why they're so stubborn. Maybe i'll see if i can get a bearing
puller on the cheap. Thanks for the advice guys.

Try spraying penetrating oil (like WD-40) on the splines and let it sit
for a day or so. The penetrating oil may free up the crank and make it
easier to remove.

i'd go for the screwdriver option.. although shove abit of very thin oil
on it or rub some silicon grease on it and leave it for a little bit...
adding some silicon grease in the gaps witha paper clip or sommit will
really help it slide as soon as you've made it budge.

the easy way to remove the cranks from a Qu-ax is to use a bearing
puller and remove the bearing and the crank at the same time . then you
will need a plastic or rubber hammer and vise to put them back on. Put
the bearing on and turn the unicycle over on top of the vise and hit it
with a hammer and you are done. This is the way we do it at
Municycle.com. The newer Qu-ax have threads for a crank puller in
them.😄

Well I hope you can get them off, but when you put them on again make
sure to not only put grease on but also lots of anti-sieze.

I should have mentioned this in my first post but I did put on WD40, and
then Marvel's penetrating oil, which works much better, and still no
luck. I'm going to get/borrow a bearing puller soon. I think that will
work.
