My neighbor has a 1950 Oliver 77 that we use regularly for baling on my hobby farm. The engine was rebuilt about 10 years ago. The oil pressure has always shown in the medium-to-high range on the gauge until yesterday, when it started showing somewhat low. Here are some questions:
1) Since the oil pressure gauge may be defective, does anyone know the correct pressure in pounds per inch when the engine is warmed up and running at regular RPMs?
2) Is the oil pressure adjustable in this model of tractor? My neighbor's owners manual does not seem to address this.
3) Any suggestions on where to rent a calibrated oil pressure gauge?
Thanks for any help!
