Re: Oil pump question

Hi folks

A couple of weeks ago my son Paul and I drove some
5700 kilometers to Phoenix to pick up a truckload of 1920-22 E4 parts. 
Included was a complete 1920? motor and transmission with all accessories. 
The motor was free so after dropping the pan, checking out a couple of rod
bearings (all good) cleaning out the pan, I filled it with oil, arranged a fuel
supply and fired it up after sitting for some 55 years.  All sounded good
but no oil pressure.  I had fitted a gauge to the pump outlet.  I have
pulled the pump off about 4 times.  Connected it back to the suction line,
worked it by hand and lots of oil coming out of both the  port that goes
into the timing gears, etc and the gauge tube. Ran it again.  No pressure
indicated.  Dismantled the pump, cleaned it all out, checked other pumps (3
pumps, 3 different springs).

 

This is probably one of the simplest mechanical
devices made but I am buffaloed.  All is free, ball checks are in place, it
has suction,  Stroke adjustment is disconnected and set to max.  I am
reluctant to run it any more until I have confidence that oil is actually
circulating and getting into the troughs.  Any ideas?  I have dealt
with these simple pumps for many years but this is a new one on me.  The
gauge is good by the way.

 

Thanks for any advice
