Is severe internal pump chatter or rapid system pressure fade threatening to sideline your mini excavator on high-priority job sites? When a warped retainer plate allows high-speed piston shoes to lift off the swash plate face, violent metallic scratching quickly destroys internal pump tolerances. Overhaul your hydraulic core with the high-rigidity RITO PVK-3B-725 set plate immediately.
