Product Overview
708-1S-00240 is high-grade interchange hydraulic fan motor custom-built for Komatsu D-series bulldozers, perfectly matching D61EX-15, D61PX-15, D65EX-15, D65PX-15, D65WX-15 and D85EX-15 bulldozer models. Installed inside the bulldozer cooling loop, this hydraulic motor powers radiator fans steadily to dissipate excess heat from engines and main hydraulic assemblies during demanding earthmoving, mining and land-clearing work.
Adopting high-strength cast housing and precision-ground internal hydraulic parts, the motor achieves excellent pressure endurance, wear resistance and reliable sealing performance to stand up to rough bulldozer work conditions including heavy vibration, abundant dust and drastic ambient temperature swings. It strictly complies with OEM dimensional benchmarks, which enables seamless drop-in installation. You do not need to rework mounting brackets, adjust piping layouts or modify fan fittings during maintenance, significantly shortening equipment downtime.
Product Highlights
✅ Adaptive Proportional Variable Speed Cooling
Built-in DC12V proportional solenoid allows stepless fan speed adjustment. Rotation speed rises automatically under high-temperature heavy-duty bulldozing work and lowers during light workloads, decreasing engine power waste and fuel usage.
✅ Precise OEM Interchangeable Dimensions
Mounting holes, oil port layouts and output splines fully match original factory specifications. On-site replacement can be completed rapidly without drilling or pipe refitting, minimizing bulldozer downtime on construction sites.
✅ Vibration-Resistant Reinforced Cast Iron Housing
Thick integrated cast iron shell absorbs powerful vibration produced by dozer blade cutting and bumpy off-road travel, preventing shell cracks and internal component dislocation.
✅ High-Performance Anti-Dust & Anti-Mud Seal System
Tiered fluorine rubber oil seals paired with outer dust gaskets block fine dirt, loam and muddy splashes typical of earthmoving projects, lengthening seal lifespan and lowering leakage risks.
✅ Strict Multi-step Factory Quality Screening
All finished products go through pressure holding leak tests, speed accuracy calibration and long-duration full-load aging trials, effectively filtering defective batches to cut later maintenance expenses.
✅ Dual Purchase Options for Different Budgets
Brand-new assemblies fit strict maintenance requirements of large rental fleets; professionally remanufactured versions replace all worn internal parts to offer economical solutions for bulk purchases.
✅ Wide Compatibility For Popular 15-Generation Dozer Models
One spare part covers six mainstream D61, D65 and D85 bulldozer variants, simplifying spare part categorization and warehousing work for dealers.
✅ Low-Vibration Stable Rotation
Precision-machined internal rotary components undergo dynamic balancing treatment, cutting operational noise and vibration, and protecting radiators as well as peripheral hydraulic fittings.
✅ Optimize Long-Term Machine Durability
Stable thermal control holds engine and hydraulic systems within ideal temperature ranges, slowing down aging of engine seals, main hydraulic pumps and rubber hoses.
✅ Convenient Worldwide Logistics & After-Sales Support
Sea, air and express shipping options are all available globally; tiered wholesale discounts apply to bulk orders with standardized six-month warranty protection.
