5 minute(s) of a 636 minute read

well got a text from the guy at the machine shop a week or so ago, and he said he was making progress. looks like they were doing the line bore

hought i would post a few pictures of the completed oil pump for my 1929

here are a few of the spare oil pump i did as well.

i really wanted to test the pump before installing it on the car and then find out it does not work. so i came up with a test platform to test it

cost me $0 and took me about 15 minutes to set up. used some scrap wood i had lying around in the scrap pile and used a 1x6 and drilled a 1" hole in the center, then sanded it out until the oil pump would slide it with a tight fit. used my foil pan 8x8 that i sue to change the oil in my generator as the oil pan reservoir.  grabbed some scrap 2x4's out hte pile and stacked them up until the oil pump suction tube barely was above the foil pan. (no oil yet) then used 2 scrap 2x4 wedges to angle the foil pan for quick oil return to suction. sued a scrap piece of tubing i had laying around, as i wanted to be able to SEE the oil coming out of the pump discharge. found a piece that fit snug on the threads on the discharge tube connector. did a dry run of oil pump, i use my 12v cordless drill to do this, same one i sue to prime the pump when on the car. Low is 400 RPM and high is 1200 rpm so well with in the range of the car itself !! no over driving the pump by any means. made sure everything moved freely, everything was set and workable. poured in a quart of fresh oil in the pan, used the wedges to keep the pool of oil at the pump suction (one corner of the foil pan) then adjusted the pump so it was a tad above the bottom of the foil pan. and away we went, i held onto the pump the first few spins to make sure it did not airplane propeller on me !! took a few seconds and then primed right up and away we went. had a nice steady stream of oil coming out of the pump.  I was really surprised at how much oil it actually pumps, the flow was crazy.  

Yeah i know my setup was primitive, BUT it served its purpose and the pump works !!  so i bagged it and tagged it to go back in the engine when it returns !!

I also tested the spare i built and same results, so i am happy.

also shot a few videos...

Here is basic test on LOW @ 400 RPM

Here is same basic test on LOW @ 400 RPM but with close up of oil coming out of tube
