Lots of things to check. The injection pumps until 1985 had a plastic weight-retainer ring inside the pump that falls apart. Same as many farm tractors have. It was eliminated in 1985 and all older pumps when repaired got updated. Kind of rare to find a 6.9 today that was not updated a long time ago.

Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
