Product Overview
708-2H-00322 is OEM-standard heavy-duty hydraulic cooling fan motor exclusively matched for Komatsu PC1250 super-large mining crawler excavator. As the core radiator cooling drive component for heavy mining machinery, this fan motor outputs ultra-stable high hydraulic torque to drive oversized radiator fan assembly. It continuously dissipates massive heat generated by large-displacement engine, main hydraulic pump and integrated radiator during round-the-clock full-load open-pit mining, massive ore stripping and large-scale earthmoving projects, effectively eliminating overheating faults and unplanned production downtime, ensuring uninterrupted stable operation of PC1250 mining excavator under extreme high-temperature harsh mine conditions.
All mounting hole spacing, hydraulic oil port layout, internal heavy gear structure and output shaft dimensions fully comply with original Komatsu OEM standards, supporting direct drop-in replacement without cutting, drilling or pipeline modification during field maintenance, greatly cutting equipment downtime and repair labor cost for mining yards and repair workshops.
Product Highlights
✅ Exclusive 1:1 OEM matching for Komatsu PC1250 super large mining excavator
All mounting holes, oil ports and shaft size fully consistent with original factory parts, zero adaptation failure during replacement for heavy mining machine.
✅ Direct plug-and-play drop-in installation
No cutting, drilling or pipeline rework needed during maintenance, cutting on-site repair time by over 50% and lowering labor cost for large equipment repair workshops.
✅ Extra thick reinforced heavy cast alloy anti-rust housing
Solid super thick alloy shell with double anti-corrosion coating, superior anti-impact, dust-proof and mud-proof performance, perfectly fit severe mine and quarry construction site environments.
✅ Oversized high precision CNC heavy-duty internal hydraulic gear core
Precision machined heavy gear set brings ultra-low internal leakage, stable ultra-high torque output and smooth fan rotation, maintaining constant efficient cooling under non-stop heavy ore mining workloads.
✅ High-temperature oil-resistant integrated sealing system
Heat-resistant wearproof rubber seals effectively resist high-temperature aging and hydraulic oil leakage, reducing frequent after-sales maintenance frequency and long-term mine production operation cost.
✅ Large-flow low-resistance optimized internal flow channel
Reduces hydraulic system power loss, decreases excavator fuel consumption during round-the-clock full-load mining operation, saving massive daily production expenditure for mine owners.
✅ Stable performance under continuous extreme high-temperature super heavy load
Sustained reliable cooling drive output under non-stop heavy mining workload, effectively controlling radiator temperature and avoiding overheating shutdown leading to huge production loss.
✅ Triple strict factory full performance inspection
Each finished fan motor undergoes pressure fatigue, long-hour rotation endurance and full leakage triple testing before shipment, unified stable quality for bulk export to global large mining regions.
✅ Wide applicable scenarios for super heavy mining engineering
Ideal matching spare for super open-pit mining, large highway earthmoving, mega stone quarry, super municipal infrastructure and massive land leveling projects equipped with Komatsu PC1250 excavator.
✅ Flexible global wholesale procurement policy
Support small-quantity sample trial order and full-container mass supply, stable stock supply for machinery repair shops, mining equipment leasing companies and overseas spare dealers.
