My Cub has no oil pressure

Posted by Mark on February 16, 2003 at 16:03:09 from (24.59.249.185):

Stats
1952 farmall cub ser# 151xxx.
Pulled off the hedgerow last year.
Motor not stuck
Oil in the pan a little black but not bad.
Compression #1 65 #2 63 #3 59 #4 60
Anti freeze tested -20f.
Valves lash within specs.
The owner said that it ran when he parked it there 7 years ago.
I rebuilt the carb and changed all the fluids, new plugs, tested wires, etc, etc.
I've worked on many of these old tractors but never a Cub.
This tractor starts like a dream and runs very well.
But after and new filter and 30w oil I still have no oil pressure. (when it runs for 1 minute)
I did not check the oil pump since that would require a tractor split. I removed the oil pan and checked the screen it was fine.
I removed the oil pressure guage and tested it with the air gun; it works fine.
I removed the oil pressure regulator and the one plunger at the end of the spring seems to be a little out of round but with a magnet it moves in and out ok.
Am I missing something or is the oil pump in this tractor bad.
Thank you in advance for all your help.
Mark
