Mid-size excavator pump pressure unstable or hydraulic system sluggish? The K3V63DT dual axial piston pump loses flow efficiency as rotating group clearances open up with wear. RITO supplies this complete pump assembly with coupling and drive plate, letting you restore both pump sections and the drive interface in a single installation.

In StockK3V63DT Hydraulic Pump Assembly with Coupling and Drive Plate (Kawasaki) for mid-size excavator applications. The K3V63DT is a dual-section variable axial piston pump widely fitted to 13-20 tonne excavators. Coupling and drive plate are matched and supplied together to ensure correct engine-to-pump torque transmission without the misalignment or vibration that causes early shaft bearing failure.

Both front and rear pump sections are new, eliminating the risk of the surviving old section failing shortly after a single-section repair.
Drive plate and coupling pre-balanced to K3V63DT specification, preventing torsional resonance that causes early main shaft bearing failure on high-speed pump input shafts.
Pressure and flow regulators factory-calibrated to K3V63DT power curve for correct power limiting and smooth response from first start-up.
K3V63DT fits a broad range of 13-20 tonne excavator models from multiple brands, providing workshop inventory efficiency for multi-brand repair operations.
FAQ
Q: What distinguishes K3V63DT failure from a control valve or relief valve problem?
A: Test case-drain flow from both pump sections at rated engine speed. If combined case drain exceeds OEM spec (typically 15-20 L/min for this pump class), the pump is worn. Control valve or relief valve problems show normal case drain with pressure anomalies.
Q: Should I replace K3V63DT with a new pump or repair the existing one?
A: If case-drain flow is above OEM limit and machine hours are high, a new pump assembly is more economical than repair when labour cost and parts cost are compared, particularly for remote sites without access to pump calibration equipment.
Q: What is the correct break-in procedure for a new K3V63DT pump?
A: Run at low pressure and partial load for the first two hours, check for leaks and abnormal noise, then gradually increase to full working load. Replace the hydraulic return filter at 50 hours after installation.
Q: How to confirm K3V63DT fits my excavator?
A: Verify the existing pump model is K3V63DT. Match coupling spline, flange bolt circle and port sizes. Provide machine model and serial number for cross-reference.
Q: What quality options are available?
A: We provide original, OEM and high-quality aftermarket versions with stable supply capability.
