580D CASE STEERING

[J_J]

You can do that, but air normally will be expelled after a couple of cycles.

I'll say it again:

The hydraulic pump on the 580D is divided into two sections with a common inlet.
One section works the steering, the other section works the loader and backhoe functions.

(See attached diagram)


They never built a 580D without powersteering.

Check your steering pressure. If you have sufficient pressure and flow from the power steering pump, then you must have mechanical binding, i.e. king pins and/or bearings.

x 2.......What the OP'r is calling a "Steering Pump" is actually a steering valve to distribute oil..........
