Fan Motor 708-7S-00352 for Komatsu Dozer

Product Overview

This 708-7S-00352 hydraulic fan motor with interchangeable part numbers 708-7S-00350,708-7S-00351,708-7S-00352 is a direct OEM replacement cooling core component for multiple Komatsu bulldozer models.Equipped with electro-hydraulic proportional variable speed control system, it automatically adjusts fan rotation speed according to real-time engine and hydraulic oil temperature, precisely regulating radiator heat dissipation to avoid overheat shutdown under heavy-duty mining, land leveling and earthmoving operations.

All fan motors are manufactured with heavy-duty cast iron housing and multi-layer high-temperature fluorine rubber oil seals, perfectly matching original installation dimensions for plug-and-play replacement without modification. Every finished unit undergoes strict leakage test, high-pressure endurance test and long-time full-load aging test before delivery, featuring stable operation, low noise and long service life. We provide brand new and remanufactured fan motors with sufficient stock, fast global shipment and complete quality warranty for machinery repair shops and bulk wholesale buyers.

Product Highlights

✅ Multiple Interchange OEM Part Numbers

3 sets of interchange part codes (708-7S-00350 / 708-7S-00351 / 708-7S-00352) cover the same assembly, meet different machine original part marking demands, convenient for spare parts inventory management.

✅ 1:1 OEM Matching Mounting Size

Consistent flange hole layout, spline shaft specification and oil port position with original fan motor, no cutting, drilling or refitting required, finish on-site replacement within 30 minutes.

✅ Intelligent Variable Speed Heat Dissipation

Electro-hydraulic proportional speed control adjusts fan RPM automatically based on machine working load, balance cooling efficiency and fuel consumption, effectively protect engine and hydraulic parts from high-temperature damage during long-time heavy work.

✅ Heavy-Duty Anti-Leakage & Anti-Corrosion Structure

Thick reinforced cast iron shell with anti-rust coating, multi-layer high-temperature resistant fluorine rubber oil seals prevent hydraulic oil leakage in dusty, high-temperature construction and mining sites.

✅ Strict Factory Triple Testing

1. 30-minute 20MPa pressure holding leakage test

2. 2-hour full-load continuous running aging test

3. Electro-hydraulic speed regulation linearity test100% inspection before shipment to eliminate defective products.

✅ Wide Compatibility For Komatsu Dozers

Covers full D61, D65, D85 series bulldozer sub-models, one fan motor assembly fits dozens of mainstream Komatsu dozer machines, ideal choice for repair stores and construction fleet maintenance.
