Air Compressor Pulley(s)

[Squirt-Truck]

Ok, this is getting irritating...
Looking for information on the split air compressor pulley.
1. How many different sizes are there?
2. Is the belt center line different on the different pulleys?
3. How many different pulley thicknesses are there?
4. how many different clamp configurations are there.

I have a broken outer pulley, it is 7-1/2 inches in diameter.
The replacement (thanks Dumpster) is 7 inches in diameter and has a longer nose so that it will not fully contact the compressor side. Additionally, the "new" half is completely different where the lock fasteners are, the compressor wrench is not even close to fitting.

My search of the -P's has not helped.

I am so confused, I thought they were all similar.........

How did your outer half break?

Pics for comparison, might help.

I think I have one on the parts truck. I'll check tonight or tomorrow.

The flange side (not compressor side) cracked on both sides in line with the slots for the clamp fasteners.
I will bring the camera home tomorrow and get pictures. Just happened to look at the inside face while it was off, compressor was getting a new base gasket.
It would have been ugly if it had separated while running.
