Multiquip 1428621050 Piston Ring Assembly - OEM Replacement Part

The piston ring assembly maintains compression and controls oil consumption in the engine cylinder, directly affecting performance, fuel efficiency, and longevity of your vibratory roller. This assembly creates the critical seal between the piston and cylinder wall, preventing combustion gases from escaping into the crankcase while regulating oil flow for proper lubrication.

Engineered specifically for the MRH601DS vibratory roller equipped with the Kubota EA330-E3-NB3-HGMS-1 diesel engine, this OEM piston ring assembly ensures proper fit and performance. The MRH601DS operates at 3,300 vibrations per minute with 2,428 lbf of centrifugal force, subjecting engine components to constant stress. Signs that piston rings need replacement include excessive oil consumption, blue exhaust smoke, loss of power, reduced compression, and difficulty starting.

This assembly is a critical engine component for maintaining the 1,215 lb roller's full operational capacity across its 35% gradeability range and 0-1.86 mph working speed.
