Hydraulic Pump 708-1S-00910 Fan Motor Komatsu

Product Overview

708-1S-00910 hydraulic fan motor is OEM-grade heavy-duty cooling replacement part tailored for massive Komatsu bulldozer D475A-5, D475A-5A, D475A-5E0 and D475ASD-5E0.

As the pivotal drive component of the bulldozer radiator cooling circuit, this electro-proportional hydraulic fan motor modulates fan rotation speed dynamically based on real-time engine coolant and hydraulic oil temperature. It delivers powerful and steady heat dissipation during heavy mine push work, large-scale land reshaping and long uphill hauls, preventing dangerous engine overheating under round-the-clock mining shifts and cutting redundant fuel consumption through intelligent speed regulation.

Product Highlights

✅ Adaptive Proportional Variable-Speed Cooling

Built-in DC12V proportional solenoid delivers seamless stepless speed adjustment. Fan speed rises automatically under high thermal mining workloads and reduces during lighter operation, lowering parasitic power draw from the engine and saving fuel in long mining cycles.

✅ Perfect OEM Mount Compatibility

Mounting hole layouts, threaded hydraulic ports and output splines adhere strictly to factory dimensions. On-site replacement can be completed efficiently without machining or pipe redesign, drastically cutting costly downtime of oversized mining bulldozers.

✅ Extra Reinforced Vibration-Proof Cast Iron Shell

Thickened monolithic cast iron construction absorbs intense shock stemming from heavy blade cutting and bumpy mine tracks, preventing shell fracture and internal part dislocation under harsh long-term operation.

✅ Mine-Grade Multi-Layer Dust & Mud Sealing

Tiered fluorine rubber oil seals paired with heavy-duty outer dust gaskets resist dense mine dust and muddy splashes, shielding precision internals from abrasive particles and greatly extending seal lifespan.

✅ Multi-Stage Strict Factory Quality Screening

Each finished motor undergoes pressure holding leak inspection, speed precision calibration and prolonged full-load aging trials, removing defective units and minimizing later repair frequency in remote mine sites.

✅ Dual Procurement Solutions

Brand-new original-spec assemblies meet stringent maintenance standards of large mining corporations; premium remanufactured versions replace all worn internal components to bring notable cost benefits for bulk bulk orders.

✅ Broad Adaptation Across D475 Sub-Models

One spare part covers four mainstream D475 variants, simplifying spare part categorization and warehouse stocking workload for global machinery distributors.

✅ Dynamically Balanced Quiet Rotation

Precision-ground internal rotating parts receive dynamic balance treatment, mitigating vibration and operational noise, meanwhile safeguarding fragile radiator fins and surrounding hydraulic piping.

✅ Prolong Overall Machine Service Life

Stable thermal control keeps engine and major hydraulic assemblies within optimal working temperature ranges, slowing degradation of pump internals, rubber hoses and peripheral seals under continuous mining loads.

✅ Convenient Global Logistics & Standard Aftersales

Multiple shipping options including sea freight, air freight and international express are available worldwide; tiered wholesale discounts apply to bulk purchases with uniform six-month warranty protection.
