install with coaster brakes???
- Thread starter kr632
- Start date
i asked a guy at the bike shop and he printed out a list of instructions and it showed that the entire hub has to be taken apart to get the arm off because the arm is attached to the axel
i really dont know because i broke every coaster brake i ever had before i could get to the arm

Do you have a pic of it?
I see what you're saying...I didn't know that some have the brake arm made onto the axle.
All the ones i've had here had a nut holding the brake arm to the axle.
I'm sure someone else with a hub like yours will be able to help.

O.K...I see what's happening!
That is a good breakdown of the assembly, but it is not necessary to gut the whole thing from the pedal side sprocket.
The brake arm is held on by a nut.

Yep... What Jim just said!! & you might also have to bend the arm in a 'Z' shape for extra clearance to get it back on. 
Remove only the nut shown in the photo below.
It is not necessary to disassemble the entire hub.

Yes...for sure Venice
After you install the sprocket be sure to check the clearance between the sprocket bolt heads, and the brake arm...there is a real good chance you will need to add more "Z" to the bends.

the guy at the bike shop is an idiot, and whoever wrote up that coaster brake how-to, went into waaay too much detail. and the worst part, he never specified what kind of hub he had (at least, i didn't notice it in the first ten pages of his novel.)
not all coaster brakes are the same. looks like his was a shimano, which is actually one of the easiest ones to work on. it's a pain the first time, but keep track of how all the parts came out, and it gets easier everytime.
try rebuilding an old New Departure hub. it's got 20 or so alternating steel and bronze slotted discs that have to be aligned perfectly. that's no fun at all.
and seriously, the guy at the bike shop, err, "store" doesn't know how to take a coaster brake arm off? he's fired.
oh, and like jim said, i've never seen one where the arm didn't just come off by taking a nut off, and i think i've seen just about every coaster brake in existence since 1900.

would attaching the wheel to the frame(how the guy did it in the link) hel with getting the arm off, i am very limited with tools and i looked somewhere else and it said to put a closed ended wrench on the arm and turn the nut with another wrench. i dont have a closed end wrench, i have a flat head screwdriver, a drill with screwdriver attachments, 2 crescent wrenches and a small socket set, and allen wrenches
kr,
you can put the wheel back on...attach the brake arm to the frame clip...snug the axle nut on the pedal side. This may give you enough room to reach in with a cresent wrench, (between the frame and brake arm), and get a good lock on the nut.
I usually slide a piece of pipe over the arm, if the nut is really tight.
You can also use one of your cresent wrenches to clamp the end of the arm the long way. It's a little tricky to hold it like that, but it can be done. Use your other wrench to loosen the nut.

...Venice....that was good!
You're welcome kr...I can usually tell when someone needs just a bit of advice to keep the project going.

here's an easy way to take the arm off.
take the wheel off, and set in on the ground with the coaster brake arm on top, pointing at the 4 o-clock position.
step on the bottom of the wheel with one foot to hold it.
take your biggest crescent wrench and put it on the outside nut at 6 or 7 oclock.
while holding the wrench, whack the coaster brake arm with a hammer towards the wrench.
don't get all circus strongman on it, just tap it pretty good a few times.
the axle will turn, causing the wrench to loosen the nut.
to put it back on, you don't have to go as tight. just snug up the nut, then put the wrench at 4 o clock and the arm at 8 o clock, and push them together till they're tight.
remember, the outside nut and the square nut that the arms sits on are the cone nuts, and they need to be properly adjusted with the other side so you're wheel spins. that link you have should explain that part better.

Thank you all for your advice. I have everything set up and ready to go after a hour trying to get the chain to stop hopping off. I bring her outside start her up and get about 100 feet and let off the throttle pull in the clutch and tap the brakes and CLUNK the arm breaks off the frame, the chain tentioner goes into the spokes and the chain gets stuck between the spokes and sprocket. Im just having a run of bad luck and overlooking things because im frustrated and just wanna ride. I fixed her up again,everythings tight. And she rides like a dream until the master link in the chain came off. Another wait.
