Here you have a couple of broken parts that used to belong to a Rexroth
A11VO160 open circuit pump mounted on a John Deere forest crane. These
extremely well designed and built units require little attention to
deliver uninterrupted uptime, but the local Portuguese phenomenon of
traditional service negligence as far as hydraulics is concerned,
coupled with already tuff conditions forest equipment has to face, work
like a Swiss watch, supplying us with "similarly conditioned" pumps on
a regular basis.
The roller bearing on the pressure side of the swashplate wore out and finally destroyed itself (along with the rest of the pump). The thing that caught my particular attention was the fractured steel rod that connects the servo-piston to the swashplate - I bet you don't see these break every day!
