shovel head oil pump

I recently purchased my first shovel head. It's a 1978 Electra Glide. It fills the primary full of oil while not running. I was told the oil pump was the culprit. I purchased a drag specialties pump from my local Harley dealer. I'm a do it my selfer because of my budget. But there were no install instructions. Also when I purchased my pump they said it MAY require drilling. They could not tell me how to know if my application requires drilling. Has anyone on here delt with this issue. And could you give me some insight on it. Any help is greatly appreciated. Thanks.

Agreed on the ball. You can use an EVO pushrod as the end is practically identical to the ball. That way after tapping it, the whole thing just pulls out.

even with the check ball sticking & filling the crankcase,it shouldn't be getting in the primary,check the compensating nut/bolt to make sure its tight (if not,the insert in the case is loose)

We have a multi-fluted cutter that we purchased from S&S years ago for that.
Btw, insure the crank seal is in good condition, and installed correctly.

I missed the comment about the primary - read it as filling the engine.

One of the guys with more shovelhead knowledge could speak to this but I know on EVO I saw a lot of primarys fill with engine oil because the one or both of the two screws that retain the stator wire retainer to the engine case were missing or not sealed. This creates a direct leak path between the engine and primary.

I've also seen the tools that cut the seat but figured for a one time home attempt that might be a little pricey.

Regarding the comment about drilling the pump - depending on the year, I believe there is a fixture or tool to do that if necessary - I would look at all of the suggestions before replacing the pump - especially the crank seal suggestion.
