Common failures & inspection points
Verify steady-state and dynamic pressure within manufacturer specifications (typically 200-250 bar for steering systems) using calibrated gauges; document pump pressure drop vs. load
Visual inspection of hydraulic fluid level; check for discoloration, emulsification, or contamination; perform flow rate measurement during full port/starboard cycle
Verify pitch indicator alignment with actual blade angle using mechanical feeler gauge or laser measurement at multiple positions (0°, 35°, 70°); document hysteresis
Test valve linearity via ramp input (5% increments); measure response time <500ms; check null zone <2% spool displacement; inspect spool for scoring/stiction
Measure actual flow output vs. nameplate (swashplate displacement × RPM); perform case drain backpressure check; assess noise signature for cavitation or bearing wear
