How do you pull a crank arm off the spindle?
Although I really don't need another bike, I found a Schwinn Traveler and a Schwinn Super Sport at a yard sale this past weekend that I couldn't pass up ($20 for both). They need some cleaning and some parts need to be replaced so I thought they would make a good winter project. However, I couldn't wait and started working on the Traveler last night. Got the nuts off on the crank arms, but couldn't pull them off the bottom bracket spindle. I thought I would ask if there is a way to pull them? Any help or advice will be appreciated.

you need the crank removing tool. I brought mine from a super market for 5 euros so they can be very cheep.
I just removed a crank for you, here's how
remove pedals, with oil and 15 mm spanner rotating the oppersite direction to the way the wheels go round in forward motion
This is the bolt that holds the cranks on to the BB. remove it,
This end of the crank tool does that job
leaves you with this. remover the washer too
screw threaded end of tool into crank,
screw the pokey end in
with big spanner
the more it screws in, the further the crank gets pushed
congratulations

Yes, I also have the Park tool and it is simple to use, takes just a few seconds to get a crank off...

If they are held on with nuts as opposed to bolts, I would definitely go with the Park Tool. I had a Spin Doctor puller that worked fine with cranks that have a bolt that you remove, but it lacked the depth to reach the ones that have a removable nut. On those there is a threaded part that extends out through the crank arm, if that makes any sense.

I have the type that is identical to what prettyshady has, works fine for either nutted or screwed BB spindles.

Just make sure you take out any washer under the crank bolt too!
If not you will just pull all your threads off, but not your crank.
+1 for the park tool puller - I've had mine for years and it done the job many times, just right.

I have the Park Tool CWP-6, which is pretty much the same at the tool shown by PrettyShady. It has a removable tip allowing it to be used with either square taper or ISIS/Octalink crank systems. I don't see the CWP-6 on their site anymore, but there is a CWP-7 that seems to do the same thing.
