    Hi guys. I'm back for some more advice from the pros. Bike is running good, but after it's warmed up my oil pressure is dropping off to basically nothing, even at higher rpms. When it's cold it's about 20 psi at idle, around 50-60 psi revved up. I'm not really sure what to do about it. Running 50wt oil.

    I don't recommend this for everyone but what I would do is take it on the highway and go 80 miles an hour for maybe 50 miles or so and see what happens. If it runs fine great if it blows up you need to rebuild it

    I heard that pressure isn't important on these motors, and what matters the most is circulation.
    Say as long as the circulation of the oil is good then you're ok, even heard that too much pressure result in leaks from the heads more than good oiling.

    Let's see what the experts say...

    Haha! I'd like to avoid having to rebuild it again so soon, lol.

    How hot is it where you live??????????? Why aren't you running 60wt????????

    Low pressure can be just fine when it's hot.....

    Just a spit of oil will keep things running just fine.....

    Think I would install a new pressure relief spring in the pump ...



    Set it to factory specs .. See what that does for it ...

    Also there is this ....



    Sifton high flow pinion shaft oil pump drive gear for 1939- 1953 Overhead Valve Big Twins. 6 tooth gear increases oil flow rate by approximately 25%.

    FITS
    EL 1939-1952
    FL 1941-1953

    These pump gears will up-date the pump speed to the 73-up specs ....

    It hasn't really gotten above 80 here yet.
    50wt is what was recommended by several folks so that's what I've been using. I could try switching to 60wt and see what kind of a difference it makes.
    I do have a decent volume of oil returning to the tank, even when the gauge isn't registering pressure.

    The springs and check balls in the pump are new.

    The drive gear swap sounds interesting.

    I do still have the rotor in the outer part of the pump, as it was originally. I know you've mentioned before in this thread that there's a replacement cover that doesn't take a rotor, but I honestly don't know what the point of changing that is...

    Cast iron oil pump cover includes inner cover plate but not the rotor.
    Cover has correct shape for 1941-1949 models but does not accept rotor.

    EL 1941-1949

    Your Service Manual tells all about the rotor's function .....

    Oil pressure is better now! Went with an '83 up spring.

    Bike is running great with about 700 miles on the rebuild so far, but still experimenting to figure out exactly what it wants for a warm start procedure. Sometimes it starts on the first or second kick, sometimes it's REALLY stubborn.

    Well, back to the drawing board after the bones heal.... Thanks to an 83 year old with poor eyesight who decided to pull out in front of me. No time to even touch the brakes before my boy and I were flying over the top of his car. We're alive, but quite broken.

    I'm surviving. Both arms broken,,, the left really shattered and now held together with plates, pins, screws and wires. Broken nose and ribs. My boy has a broken arm, 3 ribs, and 5 pelvic fractures. Just happy to still be breathing!
