Okay, I am  thoroughly confused.  Had a loose of power steering when Cummins installed new engine.  they deny fault - say it was "already going".  It may have been "already going", but it was still power and not Armstrong Power!!!  Anyway it is there in low gear at high rpm, but not there normally and at lower rpms.  I was thinking power steering pump (a special made by Vickers for Foretravel), but in researching I keep running across the Sheppard M100PDP1 steering box as a possibility.  Was told that the the Vickers is not normally a problem, while several of the Sheppard boxes have been replaced.  Just how does one determine which unit is at fault?  Sheppard told me to take it to a International truck dealer to have the box analyzed.  Says it should be a hour of service to test it.  Says International truck dealers  have all the proper tools and knowledge, while other shops don't normally.

Start by changing the hydraulic system filters.  That will both insure that restriction in the filters is not the cause and also let you determine if there is metal in the system.

Don't have any hydraulic system filters on the U225.  It does not have the hydraulic fan or pump like the U240 has.  Only the Vickers power steering pump and Sheppard steering gear.
