Displacement limiter
All pumps are designed with optional mechanical displacement (stroke) limiters factory set to max.
displacement.
The maximum displacement of the pump can be set independently for forward and reverse using the
two adjustment screws to mechanically limit the travel of the servo piston. Adjustment procedures are
found in the Service Manual. Adjustments under operating conditions may cause leakage. The
adjustment screw can be completely removed from the threaded bore if backed out to far.
