718438 Swash Plate Assembly for Kawasaki K5V160, K3V180 and K5V200 piston pumps. This assembly is used in Doosan DX300, Volvo EC460B and Sany SY375/SY380 excavators. Precision-ground sliding face and accurate tilt angle restore rated piston stroke and pump displacement. Cross-references apply across K5V160 / K3V180 / K5V200 variants using the same 718438 swash plate geometry.

Precision-Ground Sliding Face Swash plate face ground to Ra 0.4 and flatness within 3 micrometres, minimising piston shoe drag and restoring rated pump efficiency. OEM Tilt-Angle Accuracy Plate angle machined to OEM specification for K5V-series pumps so pistons achieve full rated stroke at maximum displacement without bottoming. Matched Piston Shoe Interface Surface hardness and finish selected to pair with OEM-spec bronze piston shoes, preventing edge contact and early slipper wear. FAQ Q: What symptoms indicate the 718438 swash plate is worn?A: Pump flow falls below rated output on a flow meter test, piston shoes show uneven or edge wear patterns, pump case-drain flow is above OEM limit, and hydraulic oil temperature rises faster than normal during operation. Q: Should I replace piston shoes when fitting a new 718438 swash plate?A: Yes. Piston shoe sliding faces wear in a matched pattern with the swash plate. Fitting a new flat swash plate against worn shoes causes concentrated edge contact that rapidly re-scores the new surface. Q: Does 718438 fit K5V200 as well as K5V160?A: Yes. The 718438 swash plate covers K5V160, K3V180 and K5V200 variants. Always verify the pump model plate and confirm K5V series compatibility before ordering. Q: How to confirm 718438 is the correct swash plate for my pump?A: Match the existing swash plate part number 718438, pump model (K5V160/K3V180/K5V200) and machine model. Provide pump serial number to our team for confirmation. Q: What quality options are available?A: We provide original, OEM and high-quality aftermarket versions with stable supply capability.
