Larry-
It's not necessarily a technical name as much as it is a common name. I can't remember what IH called it. And it shouldn't be hard to slip on the crank. Be sure and clean the crank/keyway well with some very fine emery cloth. I always clean the hole/keyway in the pulley as well. With a touch of anti-seize it should slide right in place. The key is usually the most difficult part but rather easy just the same. I also use red thread locker on the set screws when installing this pulley because it takes so much of a beating. I've seen several worn keyways because of this pulley coming loose.
