Hydraulic Pump 708-1S-00241 Fan Motor Komatsu

Product Overview

708-1S-00241 hydraulic fan motor is OEM-standard cooling replacement part made for Komatsu bulldozer D61EX-15, D61PX-15, D65EX-15, D65PX-15, D65WX-15, D85EX-15.

Serving as the core drive unit of bulldozer radiator cooling loops, this electro-proportional hydraulic fan motor dynamically adjusts fan rotational speed responding to coolant and hydraulic oil temperature fluctuations. It delivers stable heat dissipation during intensive earthmoving, slope grading and uphill heavy-duty bulldozing, preventing engine overheating during long continuous work shifts and cutting unnecessary fuel consumption through intelligent speed regulation.

Product Highlights

✅ Intelligent Proportional Speed Regulation

Built-in DC12V proportional solenoid achieves stepless fan speed adjustment. It boosts rotation speed amid high-load hot bulldozing operations and lowers speed under light-duty scenarios, reducing parasitic engine power loss and fuel expenditure.

✅ Perfect OEM Dimensional Interchangeability

Mounting flanges, threaded oil ports and output splines match factory original parameters precisely. Field replacement can be finished rapidly without extra machining, greatly shortening equipment downtime at construction sites.

✅ Shock-Resistant Heavy Cast Iron Housing

Monolithic thick cast iron shell dampens strong mechanical vibration from uneven terrain and frequent blade loads, effectively avoiding shell fracture and displacement of built-in internal parts.

✅ Advanced Multi-Layer Dust & Mud Resistant Sealing

Tiered fluorine rubber oil seals together with outer dust gaskets adapt dusty mines and muddy earthwork sites, stopping abrasive dirt from eroding inner components and extending seal service life.

✅ Rigorous Multi-Stage Factory Quality Checks

All finished motors pass pressure holding leak inspection, speed accuracy testing and extended full-load aging trials, removing defective products to cut down later repair frequency and costs.

✅ Dual Procurement Solutions

Brand-new assemblies meet strict maintenance standards of large-scale machinery fleets; professionally remanufactured units replace all worn internal core parts to deliver cost advantages for bulk wholesale orders.

✅ Broad Model Coverage For Popular 15-Generation Dozers

One part is adaptable to six mainstream bulldozer variants in the D61, D65 and D85 product lines, simplifying spare part categorization and warehouse stocking work for distributors.

✅ Balanced Low-Noise Rotation

Precision-ground internal rotating assemblies are dynamically balanced to lower running vibration and noise, meanwhile protecting radiator fins and connected hydraulic pipelines.

✅ Stabilize Long-Term Whole-Machine Condition

Precise thermal regulation keeps engine and hydraulic assemblies staying within optimal working temperature bands, slowing the aging pace of pump internals, rubber hoses and various sealing pieces.

✅ Flexible International Shipping & Aftersales Service

Multiple shipping selections including sea freight, air freight and global express are available, tiered bulk discounts can be unlocked, and the six-month international warranty offers stable post-purchase protection.
