Oil Pressure Gauge Repair

RMGeorge · Dec 3, 2022

My Rochester oil pressure gauge from my Ford NAA is stuck on 40 psi. It s old, rusty, and hasn t been used in years. I would like to restore it instead of replacing it. Anyone have any experience opening up the gauge for inspection and repair?

Is your tractor nearly a perfect example of a machine restored to the gnats-arse? If not you are a gluten for punishment! Get a replacement and save yourself the headache. Of course it is your tractor and you can do as you want. Here is an example of one step that has to happen. I am certain there is also some sort of fixture needed to re-crimp the bezel to close it back up.

I plead temporary insanity. After seeing what s involved, it s obviously not practical. My NAA project is more a rejuvenation than a complete restoration. However, I am, sometimes, a glutton for punishment.
Thanks for your advice and the video link!

There's a place called Evergreen Gauges. I'd search them. All their gauges are calibrated, not just for decoration.

Go to the FORD section of parts soldhere by our host YT.
Under NAA they list four different oil gauges for less than $17.
