Hydraulic Pump 708-1W-00131 Fan Motor Komatsu

Product Overview

708-1W-00131 hydraulic fan motor is OEM-grade heavy-duty cooling replacement part precisely engineered for Komatsu PC60-7 and PC70-7 compact excavators.

Serving as the core power assembly of radiator cooling loops for these two widely popular excavator models, this electro-proportional hydraulic fan motor intelligently adjusts fan rotational speed according to real-time variations in engine coolant and internal hydraulic oil temperatures. It delivers stable and reliable heat dissipation across diverse construction scenarios, including municipal trench construction, residential landscape renovation, medium-scale foundation excavation, indoor demolition refurbishment and suburban farmland development projects. Adaptive speed regulation effectively prevents engine thermal overload during frequent start-stop cycles common in construction operations, and optimizes fuel economy by cutting redundant fan rotation throughout idle intervals on busy work sites.

Product Highlights

✅ Dual-Model Calibrated Proportional Speed Control

Specially tuned DC12V proportional solenoid achieves seamless stepless speed adjustment matching the thermal output traits of PC60-7 and PC70-7. Fan rotating speed rises automatically amid intensive digging work to achieve sufficient heat removal, and lowers during work pauses to reduce idle power wastage and long-term fuel expenditure.

✅ OEM-Standard Mounting That Fits Confined Engine Bays

Reinforced downsized mounting flanges, accurately machined hydraulic port threads and matched shaft splines perfectly adapt to the built-in installation space of both excavator models. No on-site metal cutting is required in replacement procedures, greatly shortening machine downtime at construction locations.

✅ Excellent Anti-Vibration Cast Iron Shell

Thickened alloy cast iron casing effectively buffers continuous micro-shocks from frequent excavation motions, avoiding shell deformation and loose internal hydraulic components even during long-duration daily workloads.

✅ Multi-environment Dustproof and Mudproof Seal Performance

Multilayer premium fluorine rubber sealing rings paired with outer dust barriers isolate concrete dust, sandy garden soil and wet trench sludge, slowing seal abrasion for urban construction sites, garden transformation projects and muddy rural job sites.

✅ Rigorous Multi-stage Pre-delivery Quality Screening

All finished products undergo a 30-minute 22MPa pressure retention leak inspection, high-precision linear speed calibration and a 2.5-hour continuous full-load aging test. Potential manufacturing defects get eliminated in advance to lower later on-site maintenance frequency.

✅ Dual Procurement Options to Fit Different Budget Plans

Factory-new units meet official Komatsu aftermarket quality criteria; remanufactured versions refurbish worn internal hydraulic core structures properly, delivering noticeable cost advantages for wholesalers maintaining bulk excavator spare inventories.

✅ Optimize Warehouse Stock Arrangement

One spare component covers two mainstream Komatsu excavator models, cutting down the quantity of SKUs that need stocking, simplifying inventory classification and releasing capital occupied by scattered spare stocks.

✅ Dynamically Balanced Internal Rotor Unit

Internal rotating parts are processed with professional dynamic balancing technology to cut running vibration and operating noise, offering solid protection for delicate radiator fins inside narrow engine compartments.

✅ Extend Overall Hydraulic Circuit Service Life

Stable thermal regulation keeps small-displacement engines and supporting hydraulic fittings within suitable temperature ranges, slowing ageing of pump internal parts, thin rubber hoses and peripheral sealing accessories under repeated startup and shutdown cycles.

✅ Strong Global Logistics Compatibility

Compact structural dimensions reduce international freight costs, shock-resistant industrial packaging remains intact during sea shipping, air delivery and ordinary parcel transportation. Tiered bulk purchase discounts are available alongside unified 6-month international warranty coverage excluding improper manual damage and faulty mounting.
