I have really never had a problem with my pedals until now. But, the arm, that holds my left pedal is stripped so my pedal keeps falling off when I ride. Can you take it off the bike without taking the crank and everything else off. I can't figure it out, and I am persistant! Help me.
Crisis,
Sure helps to know what kind of ped.
Assuming the pedals and cranks look like the average old european bicycle, the spindle through the frame is the pedal crank spindle, or crank spindle. The pedal cranks or cranks are attached to the crank spindle with cotter pins. The pedals are attached to the cranks by screwing them in, one is a left hand and the other a right hand thread.
Think about that a while then re-post your problem.

I have a Puch Maxi Luxe 1977 model. And yes they look like what you have described. How do I get those puppies off the crank? The left side is stripped out, so the pedal won't stay in. So how do I get the spindle off? I want to replace the whole thing with another crank and the "arms" off another Puch Maxi, same year. Does that help clarify?
For the left side, there should be a nut and threaded stud on the crank near the rotating point. Loosen the nut so that it's just about off the stud (maybe a little past being flush with the end of the stud). Take a hammer and tap on it a little bit until it loosens the stud and pushes it out a bit. Then take the nut off and the stud should pull out the rest of the way. The crank should slide off, then. On most maxi's, they have a two-piece crank, and the right crank is permanently attached to the sproket and shaft assy. but the left one comes off, so if you want to replace both cranks, you'll probably have to replace the shaft and sproket, too. If your bike is an MKII or on some other bikes, the crank is three pieces instead of two.
Crisis,
I'm not surprised that you are in crisis, after I tried to explain to you what all the parts are called so that you could describe the problem, you still manage to describe your problem in a non-understandable way.
Anyway, lets try this. I am not sure if a Puch has the crank spindle connected to anything inside the motor but I think it might, maybe someone else can help here.
Look at the crank where it fits on the crank spindle, there should be something like a bolt with a nut on the end, passing through the crank at a right angle to and next to the spindle. This is a cotter pin. It is a round steel rod with an angled flat on one side so that when you tighten the nut, it wedges the crank to the spindle.
Back the nut off a couple of turns until it is flush with the end of the thread, put something heavy like a big hammer under the crank and spindle, then whack the nut with a brass hammer. This should loosen the cotter pin. Then remove the nut and drive the cotter pin out. The crank will then come off the spindle.
Some rules. Cotter pins are installed with the threads in opposite directions. Cotter pins must have perfectly smooth flats, if you can't clean them up with a file, get new ones. Most bicycle shops should have them. With the left side pedal pointed forward, the right side cotter pin should have the thread pointed down, the left side, thread up.
If this does not make sense to you, describe your problem and have someone else read it before you post. If they are confused by "those puppies", we will be too.

Ron, Do you really need to be so condasending?! I am trying to learn here and the fact that your are acting like I am an idiot isn't helping any! I appreciate your help, but try not to be a dick, okay. Geez. I guess I will cry now!
Brandon, Thanks for not making me feel like an idiot, like Mr. Ron Brown! You rule!
Ron,
Miguel tells me that you are a really cool guy, with two sweet motobecane's. Sorry to "yell at you", but I felt like I was being picked on, and I don't like to take any shit. Have a nice day.
First, thanks Miguel.
Chris, I did not mean anything personal by my post. You may have noticed that I mentioned someone else who had the same ped may be able to give you a simpler answer. Brandon did, yeah Brandon, keep it up.
Meanwhile, as you post for more help, spend as much time as you can describing the problem accurately. The more time you spend, the less we have to and it will force you to look at the problem more closely and possibly learn faster.
Happy pedding,
Ron
Your the man, Ron! Sorry that I misunderstood your intensions with that post.
Chris,
No problem, you are not the first person I have pissed off on the forum but so far, everyone seems to get over it.
Obviously, I need to improve my technique. : )
Ron
Miguel said that you are British, if I am not mistaken. Maybe the British charm is comming off the wrong way? :)
The British what????? : )
hehehe
