On the auxiliary shaft or intermediate shaft as most call it (the shaft that drives the oil pump from the timing belt) there is extra material just behind the big end race. It kinda looks like a very sharp cam lobe. I don't have a block sitting here at my desk, but I do have the shaft. Is this there for a reason? Is it an oil slinger of some sort?

I'm not talking about the fuel pump eccentric BTW.

Ideas?

I'm getting ready to machine the entire shaft smooth for less weight and possibly better balancing and I plan to get rid of this extra bump, unless it's needed for something.
