Hydraulic Pump 708-1S-00460 Fan Motor Komatsu

Product Overview

708-1S-00460 hydraulic fan motor is OEM-compliant cooling replacement part exclusively engineered for heavy-duty Komatsu bulldozer D85EX and D85PX variants.

Acting as the core power unit of bulldozer radiator cooling loops, this electro-proportional hydraulic fan motor dynamically adjusts fan rotational speed according to real-time coolant and hydraulic oil temperature. It delivers reliable heat dissipation during intensive mine grading, large-scale earthmoving and steep uphill pushing assignments, effectively preventing engine thermal overload during long continuous work shifts and lowering unnecessary fuel consumption via smart speed regulation.

Product Highlights

✅ Intelligent Proportional Speed Adjustment

Built-in DC12V proportional solenoid achieves stepless fan speed tuning. Rotation speeds rise automatically under high-temperature heavy mining workloads and reduce during light-duty periods, cutting parasitic engine power loss and overall fuel expenditure.

✅ Precise OEM Interchangeable Mounting Parameters

Mounting flanges, threaded oil ports and output splines fully match factory specifications. Field installation can be completed rapidly without drilling, welding or pipeline alteration, minimizing costly downtime for large bulldozers.

✅ Reinforced Anti-Vibration Cast Iron Casing

Thick integrated cast iron shell buffers strong mechanical vibration produced in rugged mining terrains, avoiding shell cracking and displacement of precision internal components.

✅ Mining-Oriented Multi-Layer Sealing System

Tiered fluorine rubber oil seals plus outer dust gaskets effectively intercept abrasive rock dust and mud splashes prevalent in mine sites, extending seal service cycles and reducing leakage incidents.

✅ Rigorous Multi-Step Factory Quality Control

All finished motors pass static pressure holding leak testing, speed accuracy calibration and extended full-load aging trials, eliminating defective batches to cut later maintenance frequency.

✅ Dual Purchasing Options

Brand-new assemblies satisfy strict maintenance criteria of large mining fleets; professionally remanufactured versions renew all worn internal core parts to deliver prominent cost advantages for bulk wholesale orders.

✅ Targeted Compatibility for D85 Heavy Dozer Series

Precisely customized for D85EX and D85PX bulldozers, streamlining spare part classification and warehouse stocking work for machinery suppliers.

✅ Dynamically Balanced Smooth Operation

Precision-machined internal rotating assemblies go through dynamic balancing procedures, lowering operational vibration and noise as well as protecting radiator fins and adjacent hydraulic pipelines.

✅ Optimize Long-Term Whole-Machine Lifespan

Stable thermal management holds engine and main hydraulic assemblies within optimal temperature bands, slowing aging of pump internals, rubber hoses and peripheral sealing elements under harsh mining conditions.

✅ Flexible Worldwide Shipping and Aftersales

Sea freight, air freight and international express shipping selections are available; tiered discounts apply to bulk purchases, with standardized six-month global warranty protection.
