Hydraulic Pump 708-2L-90722 Fan Motor Komatsu

Product Overview

708-2L-90722 is OEM-standard hydraulic cooling fan motor compatible with Komatsu PC600-8 and PC650LC-8 eighth-generation large mining crawler excavators. As the core drive unit of radiator cooling system, this fan motor outputs stable heavy-duty adjustable hydraulic torque to drive large radiator fan assembly, continuously dissipating massive heat generated by large displacement engine, main hydraulic pump and integrated radiator during long-hour full-load open-pit mining, ore stripping and large-scale earthmoving construction. It effectively avoids equipment overheating and unplanned production shutdown, guaranteeing continuous stable operation of heavy mining machinery under extreme high-temperature harsh mine conditions.

All mounting hole spacing, hydraulic port layout, internal gear structure and output shaft dimensions strictly comply with original Komatsu factory OEM standards, supporting direct drop-in replacement without cutting, drilling or pipeline modification during on-site maintenance, drastically cutting equipment downtime and repair labor costs for mining yards and repair workshops.

Product Highlights

✅ Dual-model universal OEM compatibilityPerfect fit Komatsu PC600-8 and PC650LC-8 two mainstream Gen8 large mining excavators, reducing spare part inventory SKU quantity and warehouse stocking cost.

✅ 1:1 OEM original dimension plug-and-play replacementAll mounting holes, oil ports and output shaft sizes match original factory parts perfectly, no cutting, drilling or pipeline rework required during maintenance, cutting repair time by over 50%.

✅ Extra thick reinforced cast alloy anti-rust housingSolid heavy alloy shell with double anti-corrosion coating, outstanding anti-impact, dust-proof and mud-proof performance, perfectly adapt harsh mine and quarry construction site environments.

✅ High precision CNC heavy-duty internal hydraulic gear corePrecision machined internal gear assembly brings low internal leakage, stable high torque output and smooth fan rotation, maintaining constant cooling efficiency under non-stop heavy mining workloads.

✅ High-temperature oil-resistant integrated sealing systemHeat-resistant wearproof rubber seals effectively resist high-temperature aging and hydraulic oil leakage, reducing frequent after-sales maintenance frequency and long-term mining operation cost.

✅ Low-resistance optimized internal flow channelReduces hydraulic system power loss, decreases excavator fuel consumption during all-day full-load mining operation, saving daily production expenditure for mine operators.

✅ Stable performance under continuous extreme high-temperature heavy loadSustained reliable cooling drive output under non-stop heavy mining workload, effectively controlling radiator temperature and eliminating overheating shutdown risk that causes production loss.

✅ Triple strict factory full performance inspectionEach finished fan motor undergoes pressure fatigue, rotation endurance and full leakage triple testing before shipment, unified stable quality for cross-border bulk export to global mining regions.

✅ Wide range of heavy mining engineering applicable scenariosIdeal matching spare for open-pit mining, large highway earthmoving, stone quarry, mega municipal infrastructure and large land leveling projects equipped with Komatsu PC600-8 / PC650LC-8 excavators.

✅ Flexible global wholesale procurement policySupport small-quantity sample trial order and full-container mass supply, stable stock supply for machinery repair shops, mining leasing companies and overseas spare dealers.
