Farmall H oil pressure gauge

my1farmall · Mar 10, 2009

I replaced the original oil gauge which was rusted up but did work somewhat.When start up it would go 3/4 of the way up and than back down to just above the red mark.Now the new gauge from the 300 series Farmall 0-75 psi will start up at about 50 psi and than go down to about 1 psi?? Engine sounds good and runs smooth,oil line i took off and is not blocked.Oil does come out at the the new connector by the new gauge but not sure of the pressure?I cant go back to the original gauge because different swaged connector i had to put on for the new oil gauge.
any ideas?? thanks

Those two gauges are telling you the same thing. Most likely you have a problem with the oil pump.

Rusty is right. Look through the archives on H oil pumps for repair insight. No big deal. Cheap. effort is required, but not much. JimN
