Last night I drilled the oil pump and smoothed everything out. I looked at the plug where the cotter pin is and it was installed correctly.
However, the pump is cast and drilling it made alot of shavings and dust. I decided I was going to take the valve, spring and cup out to properly clean everything.
I pulled the cotter pin and wasn't sure exactly how to get the cup plug out. I mistakingly pushed it in further then it needs to be. I'm sure this puts more tension on the spring?
Does anyone know how to remove it so it can be re-used or do I need to ruin it removing it and replace it?
