Hydraulic Pump 708-7W-00130 Fan Motor Komatsu

Product Overview

708-7W-00130 hydraulic fan motor is OEM interchangeable cooling drive component exclusively designed for Komatsu large excavator PC1250-8, PC1250-8r and PC1250sp-8.As the core power unit of excavator cooling system, this variable hydraulic fan motor drives radiator cooling fan to adjust fan speed automatically based on engine coolant and hydraulic oil temperature. It adopts electro-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 valve realizes stepless fan speed adjustment according to system temperature. Automatically raise fan speed under high temperature and reduce speed at low temperature, lower unnecessary engine load and save 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, complete on-site replacement within 30 minutes to cut machine downtime and maintenance labor cost.

✅ Reinforced Anti-Vibration Heavy-Duty Motor Housing

Thickened integral high-rigidity cast iron shell, excellent impact and vibration resistance to adapt harsh mine and quarry working environments, effectively avoid shell deformation and internal oil 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 range, thoroughly solve oil leakage failure 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 Options: Brand New & Remanufactured Units

Two versions available to fit different customer procurement budgets. Remanufactured motors retain intact original housing while all internal pistons, valve plates, bearings and seals are replaced with brand-new precision accessories, performance close to OEM new parts at competitive price.

✅ Exclusive Compatibility For PC1250 Series Large ExcavatorsPerfectly matched cooling fan drive component for Komatsu PC1250-8, PC1250-8r, PC1250sp-8 large mining excavators, single motor covers 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, effectively reduce running vibration and mechanical noise, extend service life of radiator, fan blade and peripheral hydraulic pipelines.

✅ Effectively Protect Engine & Hydraulic System

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

✅ Complete Global After-Sales Warranty & Flexible Shipping

One year global quality warranty for non-artificial damage. Multiple shipping solutions including sea freight, air freight and international express are supported, mass stock enables fast 1-3 working days shipment after payment, tiered wholesale discount available for bulk orders.
