The OEM-grade 708-2L-00460 hydraulic fan motor is purpose-built exclusively for Komatsu PC200-6H-A sixth-generation crawler excavator.
Optimized heavy-duty internal hydraulic layouts stabilize fan torque against recurring hydraulic pressure surges caused by continuous heavy earthmoving workloads, keeping radiator hydraulic loops within safe thermal thresholds even under prolonged multi-shift construction schedules. Reinforced alloy casing and hierarchically structured multi-layer seals greatly extend component service life in dusty urban construction zones and gritty quarry environments.

Product Overview
708-2L-00460 hydraulic fan motor is OEM-grade heavy-duty cooling replacement part precisely engineered for Komatsu PC200-7 medium-sized excavator.
Serving as the core power assembly of the radiator cooling system built exclusively for this classic 20-ton class excavator, this electro-proportional hydraulic fan motor intelligently adjusts fan rotational speed in response to real-time variations in engine coolant and internal hydraulic oil temperatures. It delivers stable and reliable heat dissipation across a wide range of heavy construction scenarios, including large-scale earthworks, highway foundation excavation, municipal infrastructure projects, mining site auxiliary operations and commercial building foundation construction. Adaptive speed regulation effectively prevents engine thermal overload during prolonged high-load excavation cycles, and optimizes fuel efficiency by cutting unnecessary fan rotation during intermittent idle periods on large construction sites.
Product Highlights
✅ PC200-7 Calibrated Proportional Speed System
Purpose-built high-torque proportional solenoid achieves smooth stepless speed adjustment tailored to the heavy-load thermal characteristics of PC200-7. Fan speed automatically ramps up during sustained deep excavation to guarantee sufficient cooling capacity, and lowers during frequent work pauses to reduce idle power wastage and long-term fuel expenditure.
✅ High-Precision OEM Mounting for Standard Engine Compartments
Heavy-duty reinforced mounting flanges, accurately machined hydraulic port threads and matched shaft splines perfectly fit the standard engine bay layout of PC200-7. No on-site metal cutting or hydraulic pipeline rework is required during replacement, significantly shortening equipment downtime for construction projects.
✅ Heavy-Duty Anti-Vibration Cast Iron Shell
Thickened high-strength alloy cast iron casing effectively dampens continuous strong shocks from heavy-duty digging operations, preventing housing deformation and loosening of precision internal hydraulic components even under long-duration high-load daily shifts.
✅ High-Performance Dust & Mud Resistant Sealing Design
Multi-tier premium fluorine rubber sealing rings paired with robust outer dust barriers isolate concrete dust, coarse site sand and damp trench sludge from internal structures, slowing seal abrasion in highway construction, large earthworks and muddy mining site operations.
✅ Multi-Stage Industrial-Grade Pre-Delivery Quality Screening
All finished units undergo a 30-minute 24.8MPa pressure retention leak inspection, precision linear speed calibration and a 3-hour continuous full-load aging test. Hidden manufacturing defects get eliminated in advance to decrease the frequency of on-site maintenance and downtime losses.
✅ Dual Budget-Oriented Procurement Solutions
Factory-new products meet strict Komatsu official aftermarket quality standards; remanufactured units fully refurbish worn internal hydraulic core components, bringing notable cost advantages for wholesalers maintaining classic excavator spare inventories and fleet maintenance departments.
✅ Optimize Fleet Maintenance Inventory Planning
This dedicated spare part precisely matches the widely-deployed PC200-7 model, simplifying warehouse SKU management for construction companies and rental fleets and lowering capital locked by redundant spare stock.
✅ Dynamically Balanced Heavy-Duty Rotor Assembly
Internal rotating components receive professional high-precision dynamic balancing treatment to suppress vibration and operational noise, delivering solid protection for large-area radiator fins inside standard engine compartments.
✅ Extend Whole Hydraulic System Service Lifespan
Stable thermal regulation keeps the large-displacement engine and supporting hydraulic system within optimal temperature ranges, slowing ageing of main pump internals, high-pressure rubber hoses and peripheral seals under repeated heavy-load operation cycles.
✅ Excellent Global Logistics Compatibility
Standardized packaging dimensions suit international freight requirements, shock-resistant industrial packaging maintains stable performance during sea freight, air transport and heavy cargo delivery. Tiered bulk purchase discounts are available, backed by unified 6-month global warranty excluding man-made damage and incorrect mounting.
