Hydraulic Pump 708-7T-00710 Fan Motor Komatsu

Product Overview

708-7T-00710 hydraulic fan motor is OEM interchangeable cooling drive component exclusively designed for Komatsu large mining excavator PC1250-8, PC1250-8r and PC1250sp-8.As the core power unit of excavator cooling system, this electro-proportional variable hydraulic fan motor drives radiator cooling fan to adjust fan speed automatically based on engine coolant and hydraulic oil temperature. It adopts proportional variable displacement control to balance cooling efficiency and fuel consumption, effectively prevent engine overheating during long-hour heavy-duty mining, quarry and earthmoving operations.

Product Highlights

✅ Intelligent Proportional Variable Speed Cooling Control

Built-in DC12V proportional solenoid valve realizes stepless fan speed adjustment according to system temperature. Speed rises automatically under high temperature and reduces at low temperature, cutting redundant engine load and fuel consumption.

✅ 100% OEM Matching Plug-and-Play Installation

All mounting hole layout, oil port caliber and spline output shaft fully match Komatsu original factory standards. No cutting, drilling or hydraulic pipeline modification required, finish on-site replacement within 30 minutes to reduce machine downtime and maintenance cost.

✅ Reinforced Anti-Vibration Heavy-Duty Motor Housing

Thickened integral high-rigidity cast iron shell with outstanding impact resistance, adapts harsh mine and quarry environments, effectively avoids shell deformation and internal hydraulic leakage.

✅ Multi-Layer Composite High-Temperature Anti-Leakage Sealing System

Imported fluorine rubber oil seals with built-in dust-proof wear-resistant gaskets, stable sealing performance within -20℃ ~ +98℃ hydraulic oil temperature, 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 screened out to greatly lower after-sales maintenance rate.

✅ Dual Supply Options: Brand New & Remanufactured Units

Two versions fit different procurement budgets. Remanufactured motors retain intact original housing, all worn internal pistons, valve plates, bearings and seals are replaced with brand-new precision accessories, cost-effective for bulk orders.

✅ Exclusive Compatibility For PC1250 Series Large Excavators

Perfect cooling drive component for Komatsu PC1250-8, PC1250-8r, PC1250sp-8 mining excavators, single motor fits three mainstream models for easy spare parts inventory management.

✅ Low Vibration & Low Noise Stable Rotation

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.

✅ Effectively Protect Engine & Hydraulic System

Real-time temperature adaptive cooling keeps coolant and hydraulic oil within standard temperature range, avoid overheating damage of engine cylinder, main pump and seals, reduce long-term equipment overhaul frequency.

✅ Complete Global After-Sales Warranty & Flexible Shipping

6-month global quality warranty for non-artificial damage. Multiple shipping ways including sea freight, air freight and international express, mass stock enables 1-3 working days fast shipment, tiered wholesale discount available for bulk orders.
