What kind of crank is this?

And how do I remove it? It's on a Schwinn Traveler III.

It's a cotterless crank. The silver cap with a slot in it should undo and come off to reveal a 14mm bolt recessed beneath; try using a coin, or a large flat bladed screwdriver. You will then need a cotterless crank removal/puller tool to get the crank arms off the bottom bracket spindle.

I have a traveler and like trev says just insert a screwdriver into the key hole looking cap and turn counter clockwise. Most of those are just plastic anyways. Under that you will see what trev is talking about.
Good maintenance to your Bike, can make it like the wheels are, true and smooth!

I know this may seem fairly obvious but take the nut off first with a socket set before you try and take the crank off.

I've made that mistake once, just about managed to salvage the crankset (I ended up stripping most of the threads on the crank)

Thanks for your help, I'll give it a try!

Jon - thanks for the tip. I've never used a crank puller before, so you probably saved me some grief.
