Are severe internal pump chatter, heavy system pulsations, or rapid piston shoe failures threatening to sideline your excavator on high-priority contracts? When a warped or loose retainer plate allows high-speed piston slippers to lift off the swash plate face, violent metallic scratching quickly destroys internal pump tolerances and causes complete mechanical seizure. Overhaul your hydraulic core and secure optimal fluid balance by installing the high-rigidity RITO 311508 set plate.
