Is a worn front cylinder block causing erratic flow and power loss in your excavator's main pump? A damaged rotor group allows hydraulic fluid to bypass internally, overheating the system and slowing down job site operations. Rebuild your pump with the premium RITO 321702 front rotating group.

Experiencing severe fluid bypass inside your main pressure cylinders or noticing a persistent drop in hydraulic cycle speeds as the oil reaches its peak operating temperature? Worn-out elastic sealing rings fail to contain high-pressure hydraulic oil within the piston chambers, letting volume flow escape into the low-pressure suction side and forcing your engine to work harder to move less material. Overhaul your pressure boundaries and reclaim original system efficiency by installing the high-resiliency RITO 311506 piston ring today.
