oil priming engine

I used 2 oil pump driveshafts to make 1. Just like in the above post, I machined off the gear teeth off of 1 shaft. Next I cut the shaft off the other. I then welded the "shaft only" into the top of the "missing teeth" drive.

Before using it, I put a generous amount of greast on the underside of the toothless gear, as to not scar the bushing. I then spin it at slow rpm with the oil sender unit removed. Once I see a drip of oil at the sender hole, I stop and install a plug or sender. Putting a gauge there too would work.

Once I reinstall the "plug". I'll spin the drill at med speed for 2 min, rotating the crank every few turns.

Good enough for gov't work....
