I was looking at my engine, trying to figure out where this white powder was comming from and I saw this slit on the alterantor fly wheel where the fan belt is on. Is this normal? It is a very purposefully looking slit cut. It does not look like a crack, all edges are square looking. I have a pic below taken with my cell phone, so it is not that great of a pic. And the white powder was road salt that did not get fully washed off.

The pic I'm seeing is the power steering pump pulley.and the slit your seeing is where they put it together.So,yes everything looks alright to me.

Ive seen that on ours Jeeps before, its ok. I took the PS pump to advance to get the pully pressed off and back onto a new pump and the guy said it wasnt normal although it had been like that since we got the Jeep back in 1994. He just gave us a new pully that didnt have the crack in it, so I didnt say anything.

Possibly to allow for heat expansion or as someone said, the way it's machined?
