    Linkbelt LS2800 controls circuit

    The 2800 is the same as the Case CX series. There is a switch that is closed when you put the armrest down or it could just be a bar that lifts up. The switch usually goes bad and the symptom is loss of pilot control. To confirm just jump wires. See attached picture.

    Case 550E Track Engagement Questions

    High range clutch has either bad piston seals, or the seal rings on the shaft are bad or I've seen those pressed drums with the reinforcement ring welded on crack and split open so the clutch will not engage. Make sure the spool at the control valve is fully stroked in both directions.
