Re: Oil Pressure!!

Unknown

I was getting very concerned that after much
messing around and running the moror only for a half minute at a time that the
troughs were getting empty.  Lowered the oil pan this morning and found
there was plenty of oil in them.  Pulled the pump off for the umpteenth
time, worked the plunger by hand until I had oil puking out and
reinstalled.  Nothing.  Removed the bottom suction fitting and no ball
fell out??  Pulled the pump again and the ball was siting in the piston
chamber.  Repeated the hand priming process, pulled the plunger and looked
inside.  There was the ball again.

 

Seems that with my energetic pumping on the plunger
that as soon as I got oil flow, and I was using much too much stroke, the oil
would lift the ball right off its seat and it would lodge in the piston
bore.  Fortunately there is enough space in there for teh piston to stroke
otherwise I would have smashed something.

 

Reinstalled again, fired it up and 3-1/2 to 4 psi
on the gauge.  Much relief after a lot of frustration and I learned
something new.

Karl,
One thing I forgot to mention....I blew comp air back down the
pickup line and listened for gurgling in the oil pan..which I heard. Did it as
double check to make sure the pick up line was clear.
Probably of no
importance....never know?

mention it I've had to prime some of mine a few times. There should be an "S"
curve in the line that loops higher than the pump to minimize the air gap in
the pump itself.

started my 1925 SS as posted elsewere. I had filled the troughs with oil for

the oil pump. Lots of pressure, so then I reinstalled everything back as it
was ..sucking oil from the pan.

assume that the pump may have been air-locked and when I supplied oil by
gravity it kicked in.

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).

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.
