Hey i have a friend with a pulley off a 92 prelude si that has splines in it (similar to a hub and bearing assembly) but it doesn't seem like the crankshaft has splines on it? Is that crankshaft indeed supposed to have splines on it for the pulley?

That's normal. You line it up with the key, it'll notch into the pulley for alignment.

I know about the keyway (sp?) But i'm talking it has like 23 splines on the crank pulley itself. I have never seen any kind of splines on a pulley before? I know a keyway should hold the pulley into position.

those splines you are speaking of serve really no purpose from what I can tell. The crank doesn't match into it or anything.

I am curious as to there purpose though also.

Just makes it easier to slip the pulley on and off (keeping rust from building up and all)

so are there splines on the crankshaft itself? And also what would cause the splines to get stripped out? possibly a cause of crankwalk?
