How much oil pressure should a 8N Ford Tractor have?
According to the 8N owner’s manual oil pressure at 3/4 throttle should be about 27 PSI. With all new bearings, good camshaft bearings & a good oil pump you can probably get more pressure by monkeying with the spring in the pressure relief valve.
How do you prime an 8N oil pump?
Get a trigger type squirt oil can and put the nozzle in the hole that the valve poppet goes into. Squirt several shots of motor oil into the hole. This oil will run down into the top side of the oil pump and collect on the pump gears. This is usually enough to prime the pump.

What should a tractor oil pressure be?
30-40 psi
Oil pressure of 30-40 psi is good. At idle, it may go as low as 20 psi. The oil gauge (and filter) is at the very end of the oil circuit from the oil pump thru the crank, etc. The oil pressure has been dropped many times before getting to the gauge.

What happens when oil pressure is low on a Ford?
Answer: The relief valve spring is designed to hold the poppet on the seat until oil pressure is 35-45 psi (Yes, the poppet IS supposed to have that flat spot on it). The relief valve only sets the maximum pressure attainable and has no effect on raising a lower pressure unless the spring is weak or broken.
What to do if your tractor has low oil pressure?
However, low oil pressure symptoms in a well used N tractor engine is almost always a combination of both. Rebuilding the engine so it again has the proper bearing clearances and pump gear clearances is the only true fix. We also hear about newly rebuilt engines that have low oil pressure.
What should the oil pressure be on a newly rebuilt engine?
We also hear about newly rebuilt engines that have low oil pressure. A proper rebuild of the engine and pump will result in a running oil pressure of 40-45 PSI cold and at least 35-40 PSI hot. If it’s less, something wasn’t done right during the rebuild, plain and simple.
Where is oil pressure relief valve on Fordson?
The easiest way I’ve found to prime the pump and get it going again is to remove the oil pressure relief valve from the front of the engine. It is a 15/16″ nut on the top front of the timing cover just below the water pump. Remove the nut and pull out the spring and valve poppet.
