I only have 25-0 psi of pilot pressure at idle. After troubleshooting I found the two check valves that connect the hoses from the steer pump and hyd. pump to the pressure reducing valve trashed, the ball and seat was wore out and the spring broken. I have new on order. Has any one else had this problem? Your help is very appreciated. Sudden?

What to do if your front end loader hydraulics fails?

If a fitting does fail, do not try to repair it–it must be replaced. The pressure hydraulic circuits endure almost guarantees any fix will fail quickly. The hydraulic piston does the work; slow and intermittent piston action is the most obvious indicator of hydraulic circuit problems.
