40 Series Oil Pressure w/ 2F. (Oil Pressure Gauge) (1 Viewer)

[DuxTom]

Evening,

What do people here generally see on their OEM oil pressure gauge w/ factory 2F motor!? I’m sure these aren’t incredibly accurate gauges, but, just curious what’s “normal” out there. This seems a little high (attached photo). Thanks!!

I found this pic on this site. Pressure would depend on if the oil is cold or is at full operating temp. You can adapt an actual pressure gauge to compare the two.

Your photo looks identical to my 1977 HJ45 (3.6L H diesel engine - mileage unknown).
The manual excert looks pessimistic to me - my idle is higher than that

My rebuilt '86 2F with '77 oil pressure regulator and gauge....shows this while cruising down the road.

I'm not sure that I'd dare take my hands off the wheel in my 45 to take a photo at that speed ha

I was going to say something similar, I didn’t know the speedometers went that high!

My 12/‘78 sits exactly in the same spot. Original 2F.
