Experiencing main pump overheating, sluggish attachment lifting, or severe system pressure drops when your excavator oil heats up during tough work shifts? Scored timing faces on your port plates let high-pressure fluid bleed off internally into the suction side, lowering volumetric efficiency and driving up fuel consumption. Overhaul your hydraulic system timing core with the high-precision RITO PVK-3B-725 valve plate.
