Hydraulic Pump 708-1S-00970 Fan Motor Komatsu

Product Overview

708-1S-00970 is high-quality OEM interchange hydraulic fan motor customized for Komatsu WA380, WA430, WA470 and WA480 wheel loaders. Acting as the vital power component of loader radiator cooling assemblies, this hydraulic motor steadily drives cooling fans to dissipate surplus heat produced by engines and heavy-load hydraulic loops amid quarry work, bulk material handling, highway construction and other demanding construction assignments.

It is manufactured with sturdy cast alloy housing and precisely machined internal hydraulic friction assemblies, delivering outstanding vibration resistance, hydraulic pressure endurance and dependable sealing properties to adapt to dusty job sites, frequent load variations and variable outdoor ambient temperatures. All mounting hole spacing, shaft dimensions and hydraulic port layouts strictly comply with Komatsu official OEM specifications, enabling hassle-free direct drop-in installation. No rework on mounting brackets, hydraulic pipelines and fan adaptors is needed during equipment maintenance, which greatly cuts downtime of wheel loaders.

Product Highlights

✅ Smart Proportional Variable-Speed Regulation

Built-in DC12V proportional solenoid achieves smooth stepless fan speed adjustment. Rotation speed rises automatically under heavy high-temperature loading tasks and drops under light workloads, reducing unnecessary engine power loss and daily fuel expenditure.

✅ Fully OEM-Matched Installation Dimensions

Mounting flanges, threaded oil ports and output splines keep consistent with original factory parameters. Field replacement can be completed efficiently without extra drilling and welding work, minimizing costly downtime of loaders on busy construction locations.

✅ Reinforced Anti-Vibration Cast Iron Casing

Monolithic thick cast iron shell buffers cyclic vibration produced by frequent bucket operations and bumpy site roads, preventing shell fracture and positional shift of delicate internal components.

✅ Tiered Dustproof and Mudproof Sealing Layout

Multi-layer fluorine rubber oil seals together with outer dust gaskets adapt high-dust quarries, concrete batching plants and muddy earthwork sites, stopping abrasive grit from eroding internal sealing structures and lengthening service cycles.

✅ Rigorous Multi-Step Pre-Delivery Quality Control

All finished units pass pressure holding leak inspections, speed accuracy calibration and extended full-load aging trials, removing defective batches and lowering follow-up maintenance frequency and spending.

✅ Dual Purchasing Solutions

Brand-new original-grade assemblies satisfy strict maintenance requirements of large loader fleets; professionally remanufactured variants renew all worn internal core parts to bring prominent cost advantages for bulk wholesale orders.

✅ Excellent Model Coverage for Popular WA Loaders

One spare part fits four mainstream WA wheel loader models, simplifying spare part classification, labeling and warehouse stocking work for machinery distributors.

✅ Dynamically Balanced Smooth Rotation

Precision-machined internal rotary assemblies go through dynamic balancing treatment, cutting operational vibration and noise, while offering solid protection to fragile radiator fins and surrounding hydraulic pipelines.

✅ Sustain Stable Long-Term Machine Performance

Accurate thermal control keeps engine and major hydraulic assemblies staying within optimal temperature bands, slowing aging of hydraulic pump internals, rubber hoses and peripheral sealing pieces under cyclic heavy-duty loading.

✅ Flexible Global Shipping and Standard Aftersales

Multiple shipping choices including sea freight, air freight and international express are available; tiered bulk discounts can be unlocked, with uniform six-month international warranty protection.
