crank pulley?
On a side note, I don't know what you mean by "a less than ideal location," but I hope you are not fixing your car say on the shoulder of a freeway. I saw a nasty accident with some guy changing a flat on the shoulder of a pretty busy freeway. Not pretty at all. Be safe.
Hope that helps anyways,

Somehow, do this job in a clean, dry (and safe!) location.
I did one with a friend a couple of years ago in an afternoon on a side street in Minneapolis where he lost his belt.
Summer weather helps a lot. Beer too.
