Experiencing severe system pressure dropouts, erratic variable displacement control lag, or loud knocking noises coming from your excavator's main hydraulic pump casing? When internal center guide pins wear down or twist out of line, the internal rotating group loses its alignment, causing the cylinder block to tilt and leading to a catastrophic pump smash. Restore perfect mechanical balance and smooth variable flow tracking by installing the high-precision RITO 711708 hydraulic pump piston pin.
