These are from early evo Harley manual. Same cases and oil pump. different bore and stroke. -

?? Sorry but I don't get what your trying to sayComment

That is how the oil flows through the engine. Did you bleed the oil down to the pump? Could be air locked. Was the pump wet or dry when you put it together?Comment

Sorry not trying to be a dick but that's not how the oil flows In a shovelComment

All I had. I referenced the haynes I got. My old one had it in there... Thanks though! Learn something every day. But just make sure its got something to pull beside air. Can be air locked like any liquid system (brake, coolant, oil) if there is air trapped between 2 sides.. Pump will just turn the air. Good luck.Comment

One, make sure all your oil lines are correct
Two, pull all the caps, two on the pump and the tappet as well (yes, you have to pull the fitting above the check ball cap)
Three, gravity should bleed that shit for you, pull the springs, ball,and plunger. You can leave the screen and it's spring in.
Four, as oil reaches each cavity, cap it off. First the check ball,l then the relief plunger, and finally the tappet screen.
Don't forget to put the ball and plunger plus springs back in.
Start that thing and watch for oil at the return into the tank.
Good luckComment

god forbid you use a oil press gauge.........Comment

Could pressure bleed the air out of the tappets.....
That done by taking off the cap and spring off of the relief and with it running stick a rod down into the hole pushing hard down on the plunger.... Make sure that you take off any oil gauges or sending units ...
By doing this, the pump will be putting out about 400 psi...Take my 45 and outrun em all ..Comment

Davestune, Gauges or sending units only tell you press is getting as far as the gauge or sensor. And not necessary with hydro tappets anyway. You'll hear it before you glance at the gauge or light going down the road. Furthermore. only a nice big calibrated handheld gauge is going to give you any sort of accuracy. What about the return side of the pump?
Dragstews, That would work if the feed gears aren't air locked. And no way just kicking it. You would need a starter motor of some sort.
Gravestate, Checking for flow at the rocker lines is a good idea, but you won't see much till it's running.
Good luck and let us know how it goesComment

That you did Sir.
Still I would gravity bleed that sucker before attempting to start it. Kicking or otherwise.Comment

I have a wonder about those A/F cases....
Seems to me that the oil route may not be the same design as OEM cases....????
The oil screen plug may be to long and could be blocking the new oil path to the lifters...
Think the ultima cases did move that path to under the plug....
Something to check out anyway....
