Product Overview
708-1U-00171 hydraulic steering pump is OEM direct replacement steering power hydraulic component specially matched for Komatsu WA380-6 and WA430-6 wheel loaders.
As the dedicated oil supply unit of loader steering hydraulic circuit, this gear pump provides stable continuous low-pulsation hydraulic flow for steering system, ensuring light, smooth and responsive wheel steering operation during high-load loading, shoveling and transportation work. It adopts high-precision grinding gear pair, effectively reduces flow fluctuation and steering jitter even under long-hour continuous operation.
Product Highlights
✅ Low-Pulsation Stable Flow For Smooth Steering
Precision ground internal gear pair delivers steady uniform hydraulic output, eliminate steering wheel jitter and heavy steering failure when loader is fully loaded, greatly improve operation comfort.
✅ 100% OEM Matching Plug-and-Play Installation
All mounting hole layout, oil port size and spline drive shaft consistent with original factory standard. No cutting, drilling or pipeline adjustment needed, finish replacement within 30 mins to cut machine downtime.
✅ High-Rigidity Shock-Resistant Pump Housing
Integral alloy cast iron pump shell with thickened wall, strong resistance to vibration and impact on mine and quarry sites, avoid pump body deformation and internal leakage.
✅ Multi-Layer High-Temperature Anti-Leakage Sealing System
Imported fluorine rubber composite oil seals with built-in dust-proof gaskets, maintain stable sealing performance at -20℃ ~ +95℃ oil temperature, thoroughly solve oil leakage problems of old steering pumps.
✅ Triple Strict Factory Performance Inspection
Each pump goes through static pressure leakage test, rated flow uniformity test and 2-hour continuous load aging test, screen out unqualified products and lower after-sales failure rate.
✅ Dual Supply Versions: Brand New & Remanufactured
Two options for different procurement budgets. Remanufactured pumps retain intact original housing, all worn internal gears, bearings and seals are replaced with new precision parts, cost-effective for bulk orders.
✅ Exclusive Compatibility For WA380-6 & WA430-6 Loaders
Perfectly matched steering power pump for Komatsu WA380-6 and WA430-6 wheel loaders, single part covers two mainstream loader models for easy spare parts inventory management.
✅ Low Vibration & Low Noise Running
Dynamic balance treatment for internal gear assembly, reduce mechanical vibration and running noise, extend service life of steering hydraulic pipelines and valve components.
✅ Extend Steering System Service Life
Stable pressure and flow output reduce impact wear of steering cylinders and control valves, cut long-term maintenance frequency and spare parts replacement cost for construction teams.
✅ Global After-Sales Warranty & Flexible Shipping Support
One year global quality warranty for non-artificial damage, multiple shipping solutions including sea freight, air freight and international express, mass stock for 1-3 working days fast shipment, tiered wholesale discount for bulk orders.
