Hydraulic Pump 708-1S-00940 Fan Motor Komatsu

Product Overview

708-1S-00940 hydraulic fan motor is OEM-grade interchangeable cooling replacement part that fits multiple Komatsu heavy machinery, including wheel loaders WA380-6, WA430-6, WA450-6, WA480-6 and bulldozer D375A-5.As the essential drive component of radiator cooling circuits for the applicable equipment, this electro-proportional hydraulic fan motor adjusts fan rotating speed dynamically according to real-time coolant and hydraulic oil temperature. It delivers stable heat dissipation whether loaders carry out cyclic loading work or the D375A-5 bulldozer undertakes heavy mine earthmoving tasks, preventing thermal overheating throughout lengthy work shifts and cutting unnecessary fuel consumption through adaptive speed regulation.

Product Highlights

✅ Cross-Model Adaptive Proportional Speed Control

Built-in DC12V proportional solenoid supports stepless speed adjustment, intelligently matching the distinct heat output traits of wheel loaders and heavy bulldozers. It raises fan speed under intense thermal loads and reduces rotation during light-duty intervals to save fuel.

✅ Strict OEM Dimensional Interchangeability

Mounting flanges, threaded oil ports and output splines fully conform to factory specifications of all applicable machine models. On-site installation can be finished quickly without drilling, welding or pipe modification to shorten equipment downtime.

✅ Broadband Anti-Vibration Cast Iron Shell

Thickened integrated cast iron casing absorbs vibration of different frequencies from loader cyclic bucket movement and bulldozer rough-terrain propulsion, avoiding shell cracking and internal component dislocation in diversified working scenarios.

✅ Enhanced Multi-Layer Dust & Mud Resistant Sealing System

Tiered fluorine rubber oil seals together with external dust gaskets adapt dusty aggregate yards, concrete plants as well as gritty mining sites, intercepting abrasive particles and lengthening seal service lifespan greatly.

✅ Multi-Stage Factory Quality Screening

All finished motors go through pressure retention leak checks, rotation speed precision calibration and extended full-load aging trials, effectively screening out defective batches and cutting long-term maintenance costs.

✅ Two Tier Procurement Solutions

Brand-new full assemblies satisfy stringent maintenance standards of large mixed machinery fleets; premium remanufactured versions replace all worn internal core components to deliver notable cost advantages for bulk purchasing.

✅ Versatile Compatibility Across Loader and Bulldozer Lines

A single part is usable for four sixth-generation WA wheel loader variants plus the D375A-5 heavy bulldozer, reducing SKU quantities and simplifying warehouse stocking management for distributors.

✅ Dynamically Balanced Rotating Construction

Precision-ground internal rotating parts undergo dynamic balancing processing, lowering operational vibration and noise, meanwhile offering reliable protection for radiator fins and adjacent hydraulic piping.

✅ Optimize Long-Term Machine Durability

Precise thermal management keeps engine and main hydraulic assemblies within ideal temperature ranges, slowing the aging pace of pump internals, rubber hoses and peripheral seals under cyclic heavy workloads.

✅ Global Logistics and Standardized After-Sales Support

Sea freight, air freight and international express delivery options are accessible worldwide; tiered wholesale discounts apply to bulk orders with unified six-month global warranty coverage.
