Hydraulic Pump 708-1W-00241 Fan Motor Komatsu

Product Overview

708-1W-00241 hydraulic fan motor is OEM-grade heavy-duty cooling replacement part precisely engineered for Komatsu PC75R, PW75R-2 and PC75R-2 excavator models.

Serving as the core power unit of radiator cooling loops for these wheeled and tracked 75-series excavators, this electro-proportional hydraulic fan motor intelligently adjusts fan rotational speed following real-time shifts of engine coolant and internal hydraulic oil temperatures. It delivers stable heat dissipation across diversified construction scenarios, including municipal roadworks, residential landscape upgrading, medium-scale foundation excavation, confined space renovation and farmland improvement projects. Adaptive speed regulation effectively prevents engine thermal overload during frequent start-stop cycles in construction work, and optimizes fuel efficiency by cutting redundant fan rotation throughout idle intervals on busy job sites.

Product Highlights

✅ Multi-Model Calibrated Proportional Speed System

Purpose-built compact DC12V proportional solenoid delivers smooth stepless speed adjustment that matches the thermal performance traits of tracked PC75R, PC75R-2 and wheeled PW75R-2. Fan speed rises automatically during heavy digging tasks to guarantee sufficient cooling capacity, and lowers amid frequent work pauses to cut idle power wastage and long-term fuel expenses.

✅ OEM-Standard Mounting Adaptable for Multiple Chassis

Downsized reinforced mounting flanges, accurately machined hydraulic port threads and matched shaft splines perfectly fit the engine bay layout of both wheeled and tracked applicable excavator variants. No on-site metal cutting is required during replacement, significantly shortening equipment downtime on construction locations.

✅ Excellent Anti-Vibration Shell Suited for Wheeled & Tracked Usage

Thickened alloy cast iron casing buffers continuous micro-shocks from digging strokes as well as road bumps encountered by wheeled PW75R-2, preventing housing deformation and loosening of delicate internal hydraulic components in long-duration daily shifts.

✅ All-Terrain Dustproof and Mudproof Sealing Effect

Multi-tier premium fluorine rubber sealing rings paired with outer dust barriers keep concrete dust, coarse field soil and damp trench sludge away from inner mechanical structures, slowing seal abrasion for urban road construction, garden transformation projects and muddy rural job sites alike.

✅ Rigorous Multi-Stage Pre-Shipping Quality Screening

All finished units undergo a 30-minute 22MPa pressure retention leak inspection, precision linear speed calibration and a 2.5-hour continuous full-load aging test. Hidden manufacturing defects get eliminated beforehand to reduce the frequency of subsequent on-site maintenance work.

✅ Dual Practical Procurement Options

Factory-new products adhere strictly to Komatsu official aftermarket quality criteria; remanufactured units fully refurbish worn internal hydraulic core components, bringing notable cost advantages for wholesalers maintaining large spare inventories covering wheeled and tracked 75R series.

✅ Optimize Overall Inventory Layout

A single spare fits three mainstream 75R excavator variants, decreasing required SKU quantities, simplifying warehouse stock sorting and freeing up capital locked within scattered spare stocks.

✅ Dynamically Balanced Internal Rotor Assembly

Internal rotating parts are treated with professional dynamic balancing technology to lower running vibration and operational noise, delivering dependable protection for fragile radiator fins housed in constrained engine compartments.

✅ Prolong Entire Hydraulic Circuit Service Lifespan

Stable thermal regulation maintains small-displacement engines and supporting hydraulic accessories within ideal temperature ranges, slowing ageing of tiny pump internals, slim rubber hoses and peripheral seals under repeated startup-shutdown cycles.

✅ Great Global Logistics Compatibility

Compact outer dimensions cut international freight costs, shock-resistant industrial packaging remains intact through sea shipping, air delivery and regular parcel transportation. Tiered bulk purchase discounts are available, covered by unified 6-month international warranty excluding improper manual damage and incorrect mounting.
