Tool to remove Crank? Old Schwinnz
An extremely Newbie question here:
What tool do I use to remove the crank on a Fair Lady?
I know its some sort of double-standard-screwdriver-type-arrangement... but since the bike(s) I am salvaging are old and rusty... I figured I better ask you all so as to get a quality tool.
Thanks

Hello. to begin with we need to know what kind if crank. there are three basic types does yours look something like this? there may be a plastic (or steel) cover over the bolt or nut. for this style (cotterless or square taper) you need either a 14 or 15mm socket to remove the nut or bolt. then you need a crank puller. https://www.parktool.com/products/det...&item=CCP%2D22

OH *blushing* this is a kids bike? like a "stingray"? it has a one piece or ashtabula crank. I forget the exact size wrench but an adjustble should work. just loosen the nut on the nondrive side. then you can use a screwdriver to turn the adjusting cone out enough to grip it.

No, I think you're in luck. You should probably be able to do it with an adjustable wrench.
You just remove all the stuff on the left side, which is all left threaded: first the pedal, then the locknut on the bottom bracket, then there will be a washer that should slide off (unless rusted solid), then the cone nut. This quite often will come off with your fingers if the rust is not too bad. Otherwise, soak in some wd-40 or pb blaster overnight, and then, holding the crank, put a screwdriver in the slot on the cone and tap with hammer. 90% of the time (in my experience) this is all that is needed. It should spin right off (if there's lots of rust in the threads there, and wd-40 or oil doesn't help, you might take a drill with a small wire wheel attached and clean the rust out of the threads, though this destroys any remaining chrome). Remove all these pieces and the bearing ring.
The secret:
To get the crank out,you will need to have removed the chainguard ahead of time. The basic strategy then is to snake the crank out in the direction of the drive side. The secret here is to feed the crank a little in that direction, cocking it slightly, then put your finger in the cup on the drive side and pull the bearing retainer out Otherwise, the crank won't come out and you'll think that you are losing your mind.
Cups can be removed, if necessary, with a piece of wood or an old seatpost as a a "punch" and a mallet. Soaking in wd40 first can help with this.
Thanks for asking a question I can answer!

Bianchigirll and Roll-Monroe-Co, thank you for the good (and prompt) information.
I'll give a try today.
