gear puller versus crank puller.....
I just learned that there are different size crank pullers. The one I need (Strong light) costs as much as I gave for the bike I need it for. I found a thread where the poster had success with a 2 arm gear puller. I can't think of a reason why this would not work; but wanted to post the question in case I am missing something obvious. It's usually the obvious stuff that I miss....
Thanks in advance.....

Its kind of touchy to get a gear puller to grab onto the strange contours of a crank. But it can work. Be careful not to scratch it up though. I used an adjustable three arm one once when I had stripped out the threads. It was unwieldy, but it got it off of there.
If you have a LBS that has been around for a while, they might have an old Stronglight puller.

Crank arms usually have 5 arms so finding two opposite places for the gear puller arms to grab might be a problem.

I've used a 3 arm gear puller.
I think it was the smallest or second smallest one offered.
not only do the arms on the crank not line up well with the gear puller, but the crank arm itself causes even more headaches of trying to properly line up the gear puller arms.
To compound the problem further, the fact that the relatively soft material the crank arm is made out of, aluminum, and that the gear puller doesn't have claws that protrude a lot makes the gear puller bite and pull right through the soft aluminum.
If you use a gear puller, use a medium sized one. Put some steel plates behind the chainring arms so the claws on the gear puller have something solid to grab onto. You will also need to use a spacer between the BB spindle and gear puller, because the gear puller's head can deform and screw into the spindle, which is no good.

like they tought me in the Marines always use the proper tool for the job. I had to use a gear puller to take off a crank (thankfully just a old Ofmega) with stripped threads and it was the worst experience ever.
buy the tool you can likely resell it at a discount pretty easy. or better still just buy one of the two sided ones.
wheredo you live anyway? is there a C&Ver near by tat can lend a hand/tool?

I would find a LBS with the right tool and pay them a few bucks to remove it or, as B-Girl suggested, see if there is a C&Ver around who will lend a hand.

Also, keep in mind that if you are trying to service the BB, you can get away with pulling just one crank arm off to pull the spindle out.

find someone on here who had the same problem and bit the bullet... offer half of original price, I'm sure they would be happy to get some of that money back?
Lol maybe a GP on a single crank puller, and a list to pass it around afterwards.

STEIN STRONGLIGHT CRANK EXTRACTOR........
I listened to the little voice and ordered the correct tool.........you should always heed sound advice from a Marine.....

I forgot (for a moment) that one of pleasures of this hobby is using a well designed and well made tool................
