Product Overview
708-7R-00700 hydraulic fan motor is OEM interchangeable cooling drive component specially matched for Komatsu wheel loader WA200-6 and WA250-6.
As the core power unit of loader cooling system, this electro-proportional variable hydraulic fan motor drives radiator cooling fan to adjust rotating speed automatically based on engine coolant and hydraulic oil temperature. It adopts proportional displacement control to balance cooling performance and fuel consumption, effectively prevent engine and hydraulic system overheating failure during long-hour heavy-load earthmoving, quarry and construction site operations.
Product Highlights
✅ Intelligent Proportional Variable Speed Cooling Control
Built-in DC12V proportional solenoid valve realizes stepless real-time fan speed adjustment based on system temperature. Automatically raise speed under high temperature and reduce speed at low temperature, lower redundant engine load and cut fuel consumption.
✅ 100% OEM Matching Plug-and-Play Installation
All mounting hole layout, oil port size and spline output shaft fully match Komatsu original factory standards. No cutting, drilling or pipeline adjustment required, complete on-site replacement within 30 minutes to reduce machine downtime and maintenance labor cost.
✅ Reinforced Shock-Resistant Heavy-Duty Motor Shell
Thickened integral alloy cast iron housing with outstanding anti-vibration and impact resistance, adapts harsh quarry and construction site working conditions, effectively avoid shell deformation and internal hydraulic leakage.
✅ Multi-Layer High-Temperature Anti-Leakage Sealing System
Imported fluorine rubber composite oil seals matched with built-in dust-proof wear-resistant gaskets, stable sealing performance within -20℃ ~ +98℃ hydraulic oil temperature range, thoroughly solve oil leakage faults of old fan motors.
✅ Triple Strict Factory Performance Inspection
Each fan motor passes static pressure leakage test, speed regulation linearity test and full-load continuous aging test, all defective products are eliminated to greatly lower after-sales maintenance rate.
✅ Dual Supply Versions: Brand New & Remanufactured
Two options to fit different procurement budgets. Remanufactured motors retain intact original housing, all worn internal pistons, bearings and seals are replaced with brand-new precision accessories, cost-effective for large quantity orders.
✅ Exclusive Compatibility For WA200-6 & WA250-6 Wheel Loaders
Perfectly matched cooling drive component for Komatsu WA200-6, WA250-6 wheel loaders, single motor covers two mainstream loader models for easy spare parts inventory management.
✅ Low Vibration & Low Noise Smooth Operation
Internal piston assembly adopts precision grinding and dynamic balance treatment, reduce mechanical vibration and running noise, extend service life of radiator, fan blade and peripheral hydraulic pipelines.
✅ Extend Whole Machine Service Life
Constant temperature adaptive cooling keeps engine coolant and hydraulic oil within standard temperature range, avoid overheating damage of engine cylinder, main hydraulic pump and sealing components, lower long-term equipment overhaul frequency.
✅ 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 available for bulk orders.
