Large excavator hydraulic output falling short of demand or main pump efficiency declining? The K3V363DT is a high-displacement axial piston pump; as barrel and slipper wear accumulates, pump flow drops and circuit pressure becomes unstable. RITO supplies this complete pump assembly with coupling and drive plate so you restore full system capacity in one installation.

In StockK3V363DT Hydraulic Pump Assembly with Coupling and Drive Plate (Kawasaki) for large excavator applications. The K3V363DT is a large-displacement dual-section variable axial piston pump; the coupling and drive plate transmit engine torque to both pump sections simultaneously. Supplying the pump with its matched drive components eliminates misalignment and fretting at the engine-pump interface.

Pressure-flow regulators factory-set to K3V363DT power curve, preventing engine overload and ensuring smooth pump response to control valve demand changes.
Pump housing and rotating group rated for K3V363DT full operating pressure, suitable for large excavator work duty including rock breaking and heavy lift.
FAQ
Q: What symptoms indicate K3V363DT pump replacement is needed?
A: System pressure cannot reach the relief valve setting even with all actuators stalled, both section case-drain flows exceed OEM spec simultaneously, pump makes a high-pitched whine at high pressure, and hydraulic oil overheats rapidly.
Q: Why is the coupling and drive plate supplied together with the K3V363DT pump?
A: Reusing an old coupling with a new pump risks residual misalignment, wear or imbalance in the coupling transmitting vibration to the new pump shaft bearing, causing early bearing failure.
Q: What hydraulic oil should be used with K3V363DT?
A: Use ISO VG 46 or 68 anti-wear hydraulic oil with rust and oxidation inhibitors as specified in the machine service manual. Flush the entire hydraulic circuit before installing the new pump.
Q: How to confirm K3V363DT is the correct pump for my excavator?
A: Verify the existing pump model plate reads K3V363DT and match coupling spline count, flange bolt circle and port sizes. Provide the machine serial number for our team to cross-reference.
Q: What quality options are available?
A: We provide original, OEM and high-quality aftermarket versions with stable supply capability.
