Bought a MF40 Industrial that had weak power steering. I
replaced steering pump and still have weak power steering in
that the wheels will turn when front end is lifted but not strong
enough to overcome resistance when wheel is braced by
hand. I spent 30 min of trying to get all air out of lines per
manual instructions. I am thinking I need to test the pump
pressure. Manual identifies the line I connect to for testing.
Do I splice into the line with a tee or one side of the line? Will
this test the system pressure or the pump pressure? How do I
make sure my new pump is opperating correctly? There is
also a small slow drip in one steel hydraulic line, but would not
think it would weaken my steering that much but maybe it is?.
Manual also says I can adjust the relief valve to add or
decrease pump pressure. Where is the valve located? I
attempted to check pump pressure on bottom inlet of pump
but fluid came out of the hose that I disconnected. Manual
said bottom inlet was the pressure line.
Could my problem also be in my steering assembly? There is
a good amount of whining during turning the steering wheel
that comes from the steering assembly.
What is the process to troubleshoot this problem?
Thank you for all your help!
