Common failures & inspection points
Visual inspection for scoring, pitting, chipping on gear teeth; measure gear backlash and contact surface wear using dial indicators; check for discoloration indicating overheating
Check for abnormal noise/vibration during operation; inspect for corrosion, spalling, or surface damage on roller/sliding bearings; verify bearing clearances per specification; temperature monitoring
Monitor leakage rate (acceptable: ~1 drop/second); inspect seal faces for wear, scoring, or hardening; check gasket compression and condition; pressure test at operating parameters
Verify oil viscosity matches pump specification (check manufacturer datasheet); test for water contamination, oxidation products, and particle count per ISO 4406; change intervals per maintenance schedule
Conduct pressure test at rated conditions; measure actual flow rate vs. specification; check for abnormal pressure drops indicating internal leakage; performance verification under loaded operation
