RITO 720786 Cylinder Block Rear K3V180DT K3V180 Hydraulic Pump Cylinder Block Rotor EC360 EC460 DH370 R375 R450 R480 Excavator

Hydraulic output instability, uneven piston sealing, and rotor wear inside K3V180DT / K3V180 pumps can quickly reduce digging strength on EC360 / EC460 / DH370 / R375 / R450 / R480 excavators. For mining contractors and fleet operators, these failures often mean repeated pump teardown and costly machine downtime. The RITO 720786 Cylinder Block Rear is developed to rebuild internal hydraulic balance and restore smooth pump operation.
