Hello, my white 4-150 hydrolic pump makes a whining noise when rpm's goes up.
Oil and filter are new.
Steering works fine.
Bad pressure on the outlets.
Looks like air bubbles in the oil reservoir.
When I turn the compensator screw, nothing changes.
When I turn steering wheel it stops whinning until I stop turning.
Pump get a little warm after 5 minutes.
3 point don't work.
Tractor was not running for 20 years.
Help is appreciated, thanks Wim.
