VH41 vs. vh45 crank pulley ?

[Stinky]

Hi guys. I'm brainstorming about using a stock pulley to drive a dry sump pump. Long story short I'd like to see if anyone has a few good pictures of a vh41 pulley or even better a picture of both pulleys next to each other. Are they interchangeable?

I'm thinking about removing the front weight and cutting off the front pulley of the stock unit. Then I would bolt on a shaft that would stick out the front and drive the pump. The problem is gettign the stock pulley short enough so the dry sump pulley doesnt stick out too far and possibly hit the stock fan.

thoughts?

I've seen two different types of VH41 pulley (depending on what accessories the stock motor came with.) But if it helps, I'm gonna be running my VH41 pulley on my VH45 crank... so they're interchangeable alright.
