1949 ford 8n

[Graham A]

Just bought a 1949 8n and was pulling a large pine log. I didn't check the hydraulics until the next day and they didn't work. So I'm wondering if I overloaded them and broke something?

Check the easy stuff first.

Make sure the PTO is engaged.

Check the fluid.

If that isn't the problem, take the inspection plate w/ the dipstick off. Make sure the control rod is connected to the pump. Look inside w/ the tractor running & the PTO engaged to see if you notice oil running from the top cover. If no oil is running down from the top cover, look at the rear of the pump in the oil and see if you notice turbulence in the bottom. (Some movement of oil will be normal with the PTO shaft turning). You could have a weak pressure relief valve which will be detected by turbulence in the oil. To check for a leak, turn the tractor off & put a ½ inch clear plastic hose on the end of the valve & stick the other end of the hose through the inspection port. With pressure in the pump, a bad valve will likely show some fluid in the hose.

Post back w/ any other questions.
