I have a 1961 3010 diesel. The power steering mostly quit and the rear remotes don't function. Brakes and rockshaft function fine. I'm guessing the valves under the dash need rebuilt or replaced as they are also leaking. Any suggestions? Thanks in advance.

Welcome to GTT.

To begin with, the hydraulic "Standby" pressure should be checked.

3000 psi gauge and a male nipple is needed.

Plug into the quick couplers at the SCV, run tractor at ~2000 RPM and engage the SCV.
Record the pressure. Should be ~2150 psi.

Is there another place to test?

Remove plug(item 30) on RH front of hyd pump housing & install fitting for gauge. How long since hyd filter was changed & suction screen checked/cleaned?

 

[JakeAdams]

About 3 hours brush hogging since hydraulic oil and filter changed and screen cleaned. Rebuilt pump installed at same time.

Was trans pump GPM output checked before front pump was replaced?

No I don't think so.

Why was old pump replaced?
