[Farmall] oil pressure

[John Hall]

Darn good question! I echo the concerns about good oil pressure when cold 
and then losing it when hot. The only exception is my T-20, it runs high oil 
pressure all the time. I had an F-12 in the shop with a badly worn engine. 
Even after new bearings it was still too low for my liking so I added Lucas 
oil to help it maintain good pressure when hot. I wonder now if the gauge 
was incorrect and giving us an incorrect reading.

I don't know how new his info. goes but send a few gauge #'s to Lee Grady at 
the archives. I doubt IH made them but there is a chance they have info that 
tells what size gauge and from whom they bought it.

Let us know what you find out. I got a Regular that runs good when cold then 
nothing once hot.
