How?

[Coaster Brake]

I'll give that a shot tomorrow, hopefully it will come apart and I won't break anything....

Here's a shot of the standard Crescent bottom bracket, which might help:
http://books.google.com/books?id=4h...scent chainless"&pg=PA639#v=onepage&q&f=false
it "differs in design and construction from the adult chain model, only where necessary to accommodate its special driving mechanism".
Best I could come up with, but I'd try to find a Crescent chainless owner at the Wheelmen before I did anything rash. Knowledge is Power.

From the chain drive picture, it looks like the left hand crank is a press fit on the crank axle and the lockring and adjuster are for the bearings, but I'd still "ask the man who owns one".

If it's press fit how about trying a battery cable puller ---cheep tool at the auto parts---sam

 

[Coaster Brake]

Well, I tried using a punch, but got nowhere with that.

It would be great if I could get a puller on there, but that would appear to be impossible.

there is patent date on the bottom bracket. can you search the patent data base for the drawings?
have some patience, you'll figure it out, don't do any heavy hitting yet. those pieces are the only ones you have and i'm thinking hens teeth to find.

I've got all the info on how it comes apart, but it just won't.
I wouldn't worry about it if I wasn't trying to paint it.

Try loosening the lockring and bottom bracket bearing adjusters- these MAY lever the crankarm out enough to get a puller underneath, or make your own puller jaws from thin scrap and bolts. Steering wheel pullers usually have a lot of options and are easy to modify.

I hope this helps

They say a picture is worth a thousand words, so I went and pulled mine apart........so to show you what I was talking about with the center punch and all.

This sprocket is from my (chain driven) 1900 Crescent model 31.

I would think is the same basic idea. As you can see from the pictures, you'll never be able to get a puller in there....... it's locked on the under side. In your case you may need to hold the crank arm in a vise while the frame is suspended in the air, then try punching it out, just make sure you are using some type of penetrating oil, etc.

"A judicious application of heat" from a blowtorch could help free things up. You really can't get better information than what okozzy gave you!
