I just bought a 1954 Ford NAA and I am in the process of doing the usual tune-up and fluid replacements. I changed the oil and used 10W30 which is what I use in a 9N I have. The tractor starts quickly and runs very smooth but the oil pressure guage didn't work when I bought it and upon replacing the guage I see the oil pressure is up around 70lbs when I first start it and then drops down to around 50lbs. Is this normal?
It's still rather cold here in the Northeast and I'm working outside so the engine isn't warming up as much as it should.
Should I be concerned about the high oil pressure? I was thinking of swapping the oil with 5W20 as I normally use my tractors during the winter months for snow plowing.
I also read somewhere that there is a valve or spring in the oil pump that can stick and cause higher than normal oil pressure.
I would appreciate any advice or suggestions from those more experienced with the NAA than I am.
Thanks. - John
