Hydraulic Pump 708-2K-00013 Fan Motor Komatsu

Product Overview

708-2K-00013 hydraulic fan motor is OEM heavy-duty cooling replacement part specially manufactured for Komatsu PC3000-6 ultra-large mining excavator.

As the core power unit of the radiator cooling circuit for PC3000-6, this electro-proportional hydraulic fan motor automatically adjusts fan rotational speed according to real-time changes of engine coolant and hydraulic oil temperatures. It provides stable, powerful heat dissipation during round-the-clock open-pit ore excavation, heavy quarry rock digging, large-scale earthmoving and long-cycle high-load mining operations. The adaptive speed control effectively prevents engine thermal overload under continuous heavy digging workloads and optimizes fuel consumption by reducing unnecessary fan power output during idle and light transit states.

Product Highlights

✅ Excavator-Tailored Proportional Speed Regulation

Heavy-duty built-in DC12V proportional solenoid delivers smooth stepless fan speed adjustment. Rotation speed rises automatically to boost heat dissipation during peak heavy-load digging, and lowers during idle transit to cut parasitic engine power loss and improve long-term mining fuel economy.

✅ Exact OEM Mount Matching Specs

Strengthened mounting flanges, thickened hydraulic port threads and precision-machined shaft splines perfectly fit the factory installation cavity of PC3000-6. No on-site metal cutting or pipeline retrofitting required during replacement, significantly shortening costly equipment downtime at remote open-pit mine sites.

✅ Shock-Absorbent Reinforced Cast Iron Shell

Integrated extra-thick anti-corrosion alloy cast iron housing buffers violent vibration from heavy rock excavation and rough off-road mine travel, preventing housing cracks and loosening of delicate internal hydraulic components through prolonged harsh mining operation cycles.

✅ Multi-Layer Dust & Mud Resistant Sealing System

Stacked premium fluorine rubber oil seals paired with oversized outer dust gaskets block ultra-fine mining dust, jagged rock debris and wet pit sludge. Seal abrasion is greatly slowed in dusty open mines, muddy foundation pits and high-temperature quarry operation zones.

✅ Multi-Stage Pre-Delivery Quality Verification

All finished motors pass 22MPa 30-minute pressure retention leak inspection, accurate rotational speed linear calibration and continuous full-load aging trials. Hidden manufacturing defects are fully screened out before delivery to reduce recurring expensive field maintenance.

✅ Dual Budget-Friendly Procurement Choices

Brand-new factory-standard motors meet strict maintenance standards of large mining enterprises; remanufactured versions fully replace all worn internal hydraulic core components, offering prominent cost advantages for bulk warehouse stocking.

✅ Exclusive Single-Model Perfect Compatibility

Purpose-built dimensional parameters achieve zero-adaptation installation for PC3000-6, eliminating mounting mismatch and leakage risks during aftermarket replacement.

✅ Dynamically Balanced Internal Rotor Assembly

Large rotating internal parts are processed via professional dynamic balancing technology to suppress vibration and operational noise, delivering stable protection for bulky radiator fins and surrounding heavy hydraulic pipelines on bumpy mine haul roads.

✅ Extend Overall Excavator Hydraulic Circuit Service Life

Stable thermal management keeps the large-displacement mining engine and key hydraulic assemblies within optimal working temperature ranges, slowing aging of pump internals, thick rubber hoses and peripheral sealing fittings under nonstop heavy mining digging tasks.

✅ Global Adaptable Bulk Shipping Solution

Durable shockproof industrial packaging performs reliably in sea freight, air cargo and international express delivery. Tiered volume discounts are available for bulk orders, backed by unified 6-month global warranty excluding man-made damage and faulty installation.
