[Farmall] Oil Pressure Gauges

Bob,
If you don't mind me asking, how much did he charge? Did he use a new face, or just give you a good used one?

Subject: [Farmall] Oil Pressure Gauges



Well, I'm finally finishing up the oil pressure gauge project thing that we 
talked about on the list 6 or 8 weeks ago. After the good list discussion, I 
sent two gauges off to a guy in WI who restores them. He took my old original, 
non working gauge, put a nice, black face with the old style logo (18113-DA), 
and was able to calibrate it so the gauge would read mid range (or straight up) 
at 2.5 psi, which should be perfect for my early 10-20 with no oil filter. He 
was unable to do anything with the reproduction gauge that I sent him. That one 
came to me with a decent black face with the old style logo (31041-DB) and the 
vender there in MD says it is supposed to be 0-15psi. Jerry in WI can restore 
these old, original gauges using glass instead of plastic lenses, putting 
original black faces in them with the part number/logo, and calibrating the 
gauge to work properly in your early IH tractor or power unit. If your 
interested in talking to him about his work,

below is some info on the project that he and I worked on regarding early IH 
gauges and oil pressures.

  Jerry, I received the gauges back in yesterdays mail. Thank you for doing a 
nice job. The one that you re-did looks real good, and that 18113DA face will 
work very well. That particular face was used on the Farmall Regular, F-20, 
F-30, I-20, and I-30, from approximately 1930 thru 1938. The F-12/F-14, W-12/14, 
O-12/14, used that 31041DB face like the other gauge I sent. The difference 
being that it has the red color on the left side of the arc. The early Farmall 
Regulars, and other early IH models used a couple various gauges, but it appears 
that they were a black face, solid white arc, and a white needle. Some had a 
black needle. The pressure ranges would vary depending on the tractor model that 
was involved. And from what I have learned, the breakdown is basically that the 
early IH tractors with oil pressure gauges from 1921 thru 1929 were in the 1-6 
psi range. When the oil filters were introduced in mid year 1929, operating 
pressures jumped a few psi, lets say 2-8psi. An!
 d when the 12 series tractors came out in 1933 (with the IH motor) they had an 
improved internal oiling system which again jumped the pressures a few psi, I'll 
guess 4-12psi, or whatever range that 31041DB gauge is calibrated. 

  thanks,
