Right now I can not figure out which pulleys I am supposed to have on the power steering pump and the crank snout. I have one pump that came off of an early 70's truck that has a small (4"wish) pulley with an inverted dish to it. with it mounted on the truck it lines up perfectly between the 2nd and 3rd sheave on the crank pulley. is there a 4 sheave pulley out there that I'm supposed to have? or do I use a different pump pulley?
My understanding is that the power steering pump runs its own belt to the crank and the AC is supposed to use the 3rd sheave on the crank, the idler. and the compressor.
I also have another pump that has a 6"wish pulley that is set back toward the pump and aligns with the second sheave of the crank but the lower radiator hose is in the way. I have seen other trucks with a lower hose that sets back a little before turning out toward the radiator. is this what i'm supposed to have?
HELP!!
