Hydraulic Pump 708-1S-00230 Fan Motor Komatsu

Product Overview

708-1S-00230 hydraulic fan motor is OEM-standard cooling replacement part specially engineered for Komatsu wheel loader WA380-5, WA400-5, WA400-5L, WA450-5L, WA470-5, WA480-5L, WA480-5.

Serving as the core power component of the loader radiator cooling loop, this electro-proportional hydraulic fan motor dynamically adjusts fan rotating speed in accordance with engine coolant temperature and hydraulic oil temperature. It optimizes cooling output during frequent loading, transporting and dumping cycles, prevents overheating faults in long-shift heavy-duty operation, and cuts unnecessary fuel consumption via intelligent speed regulation.

Product Highlights

✅ Intelligent Proportional Speed Regulation

Built-in proportional solenoid achieves stepless fan speed adjustment. It raises rotation speed in hot working conditions and reduces speed under low thermal loads, lowering engine parasitic power loss and fuel expenditure.

✅ Full OEM Dimension Compatibility

Mounting flanges, thread oil ports and output splines match original factory parameters precisely. Field replacement can be completed quickly without drilling, welding or hydraulic pipe refitting, greatly shortening machine downtime.

✅ Reinforced Vibration-Resistant Casing

One-piece thick cast iron shell absorbs strong vibration produced by loader frequent bucket lifting and rough-terrain driving, avoiding shell cracking and internal structural deformation.

✅ Advanced Dust & Mud Resistant Sealing System

Multi-stage fluorine rubber seals plus external dust gaskets adapt high-dust quarry, sand yard and muddy construction sites, effectively blocking abrasive particles to extend seal service lifespan.

✅ Rigorous Multi-Step Factory Quality Checks

Each motor passes static pressure leak test, speed control precision test and hours-long full-load aging test, screening defective products to lower later maintenance frequency.

✅ Dual Procurement Options Available

Brand-new original-grade assemblies are suitable for high-standard fleet maintenance; premium remanufactured variants with all worn internal internals renewed bring favorable cost advantages for bulk orders.

✅ Broad Loader Model Compatibility

One part fits seven mainstream WA 5-generation wheel loader variants, simplifying spare part inventory classification and stocking work for distributors.

✅ Smooth Low-Noise Operation

Precision-ground internal rotating parts complete dynamic balance processing, cutting running vibration and noise, meanwhile protecting radiator fins and connected pipeline fittings.

✅ Stabilize Long-Term Whole-Machine Performance

Precise temperature control keeps engine and hydraulic assemblies within optimal working temperature bands, mitigating accelerated aging of cylinder components, main pumps and peripheral rubber seals.

✅ Flexible Global Shipping & Aftersales Service

Multiple shipping selections covering sea freight, air freight and international express; tiered wholesale discounts are available for bulk purchases, backed by a six-month global warranty.
