Hydraulic Pump 708-2K-00014 Fan Motor Komatsu

Product Overview

708-2K-00014 hydraulic fan motor is OEM heavy-duty cooling replacement part exclusively designed for Komatsu PC3000 and PC3000-6 ultra-large mining excavators.

As the core power component of radiator cooling system for these two heavy mining excavator models, this electro-proportional hydraulic fan motor automatically adjusts fan rotational speed based on real-time engine coolant and hydraulic oil temperature changes. It delivers stable and powerful heat dissipation during full-time open-pit ore mining, quarry rock excavation, large land leveling and long-cycle heavy haul digging operations. The adaptive speed control effectively prevents engine overheating under continuous high-load work and reduces unnecessary fuel consumption by lowering fan speed during idle and light-load transit periods.

Product Highlights

✅ Dual-Model Compatible Proportional Speed Motor

Built-in DC12V heavy-duty proportional solenoid realizes smooth stepless fan speed adjustment, compatible with PC3000 and PC3000-6 two ultra-large mining excavators. Fan speed rises automatically under high-load digging for stronger cooling, and drops during idle transit to reduce engine power loss and cut fuel cost.

✅ 100% OEM Matching Mounting Structure

Reinforced mounting flanges, thickened hydraulic port threads and precision machined shaft splines perfectly match factory installation cavities of PC3000 and PC3000-6. No on-site cutting or pipeline rework needed, greatly shortening equipment downtime at remote mining sites.

✅ Vibration-Resistant Thick Cast Iron Shell

Integrated extra-thick anti-corrosion alloy cast iron housing buffers intense vibration from rock excavation and rough off-road driving, avoiding shell cracks and loose internal hydraulic components after long harsh mining cycles.

✅ All-Terrain Dust & Mud Block Sealing System

Stacked high-performance fluorine rubber oil seals plus oversized outer dust gaskets intercept fine mine dust, hard rock debris and wet pit mud, slowing seal abrasion in open mines, muddy foundation pits and aggregate quarries.

✅ Multi-Round Strict Factory Quality Inspection

All finished units undergo 22MPa 30-minute pressure leak test, precise speed calibration and continuous full-load aging test. Potential manufacturing defects are eliminated before shipment to lower recurring field maintenance cost.

✅ Dual Procurement Options for Different Budgets

Brand-new full standard motors meet strict maintenance standards of large mining groups; remanufactured motors fully replace all worn internal core parts, with obvious cost advantages for bulk warehouse stocking.

✅ Reduce Inventory SKU Pressure

One single spare part covers two mainstream PC3000 series excavator models, cutting stocked part quantity, simplifying warehouse classification and lowering capital occupied by inventory.

✅ Dynamic Balanced Internal Rotor Assem

blyLarge rotating internal parts are processed by professional dynamic balancing technology to reduce vibration and running noise, reliably protecting fragile radiator fins and surrounding heavy hydraulic pipelines.

✅ Extend Excavator Hydraulic System Service Life

Stable temperature control keeps large-displacement engine and key hydraulic components within optimal temperature range, slowing aging of pump internal parts, rubber hoses and peripheral seals under round-the-clock heavy mining workload.

✅ Global Adaptable Logistics & Wholesale Discount

Shockproof industrial packaging fits sea freight, air cargo and international express delivery. Tiered bulk order discounts available, supported by unified 6-month worldwide warranty excluding artificial damage and faulty installation.
