How do you remove a Profile crank? Profile sells a special tool to install and remove the crank. But after looking at the tool I cannot see how it would be used to remove a crank.

Re: Profile crank removal
I’ve seen Kris use the Profile tool successfully (using a rock instead of a
hammer). I have the Evercraft one from unicycle.com
http://www.unicycle.com/shopping/shopexd.asp?id=419 which works fine to
remove Profile cranks. To install, I just line it up, then beat on it a bit
with a rubber mallet.

Re: Profile crank removal
Hey John,
I had much the same ponderings and spent a good amount of time hammering
away at the thing before figuring out that I was doing nothing but pounding
the end of the axle. Thankfully the Profile’s a sturdy beast and just
laughed it off.
The tool basically acts like an extension to the axle. All you are doing is
knocking the axle out of the crank. It goes a little something like this…
Unscrew the cranks bolt.
Screw in the tool nice and tight - not too tight though. I just use my
fingers for this. When the cranks and hub were first assembled some bronze
gunk should have been smeared over the inside thread of the axle. This is so
the removal tool comes out after it’s been screwed in.
Grab a rubber hammer in one hand and the crank itself with the other. I fin
it helps to wedge the seat against something to increase leverage.
Batter away with the hammer on the exposed end of the tool. Watch you don’t
hit the spokes - I skillfully managed to bend 2 once while pounding away.
Keep checking that said tool hasn’t come loose. If it has your hammering
won’t have any effect other than to stress the tool / axle threads.
It takes some welly to get the blighters off if they ain’t been greased when
assembled previously.

Re: Re: Profile crank removal
Now I see how the tool is used. Seems like a silly way to use a specialized $20 tool.
I’ll try to rig something up with the Evercraft tool that Nathan mentioned. I use that tool to pull off my DM cranks. The Profile cranks don’t have as much to grip on to with the tool so I’ll have to play with it to get it to work better. The first time I tried using the Evercraft tool it just slipped off the crank.

Re: Profile crank removal
The Evercraft tool can be used 2 ways, narrow and wide. Use the narrow way
and tighten the bolts that hold the arms on - and go for it. It can’t be
used for every application but it has worked on both my Profile setups ok.

Re: Profile crank removal
I use a gear puller from the auto parts store. I hook the arms to the
bearing, and then the bearing pushes the crank off the end of the axle.
But when your cranks are as used as mine are, I can just unscrew the
allen bolts with my thumb, and pull/wiggle the crank off by hand.

Re: Re: Profile crank removal
I put the arms on the narrow way and the Evercraft tool works much better. I also strapped a 1-1/4" U bolt under the Profile crank to give the Evercraft tool something to grab on to.

RE: Profile crank removal
Hi Neil.
The Evercraft tool (http://www.unicycle.com/shopping/shopexd.asp?id=419)
makes Profile crank removal easy. Just slide the arms around the
bearing instead of the crank. No hammering necessary. Remove the
bearing and the crank slides off.
Most unicycle hub bearings are installed with a 3-ton press. Profile
and DM (splined version) are the only exceptions.

RE: Profile crank removal
Thanks for the pointer. Both Profiles have now reached the point where I can
just about wiggle the cranks off by hand. Besides… a rubber hammer is a
very satisfying tool to play with
