• **Custom fit for Volvo EC480E & EC950E, matched with proportional fan pump**
14641300 hydraulic piston fan motor perfectly fits Volvo EC480E and EC950E large excavators. It works seamlessly with supporting proportional fan pump. Fan rotation speed automatically adjusts according to engine temperature to match heat load, effectively solving overheating under heavy-duty working conditions.
• **Heavy-duty cast iron housing, shock & vibration resistant**
Cast iron shell treated by stress relief annealing to eliminate residual internal stress. It can withstand continuous vibration, hydraulic impact and dust corrosion on job sites. Less shell deformation and slower wear of internal components for longer service life.
• **Good anti-pollution & anti-cavitation performance**
Optimized internal flow path reduces oil turbulence and cavitation risk. Tolerates slightly contaminated hydraulic oil on site. Effectively prevents particle jamming, abnormal noise and premature component wear, ensuring continuous stable operation and less downtime.
• **Precise cooling regulation to protect whole machine**
Proportional hydraulic control realizes intelligent cooling adjustment. It keeps engine and hydraulic components operating within safe temperature range, preventing thermal damage to radiator and engine caused by overheating. It is the premium replacement part for Volvo EC480E & EC950E overhaul and daily maintenance.

FAQ 

Q1: What machine does this 14641300 fan motor fit? Is it universal?
A1: Part 14641300 fan motor is engineered for Volvo EC480E and EC950E large excavators. It belongs to the cooling hydraulic system and is not universal for other excavator models. It has to work with the matching proportional fan pump. Wrong part selection will lead to insufficient fan power and machine overheating.

Q2: What inspections are carried out before shipment?
A2: Every fan motor is fully tested on hydraulic test bench before delivery, including torque test, speed test, pressure resistance test and internal leakage inspection. Strict quality control ensures stable field performance. Test reports can be supplied upon request.

Q3: What is the warranty term, and what is excluded from warranty coverage?
A3: We offer a 12-month warranty. The warranty covers performance defects under proper installation, clean hydraulic oil and normal operating conditions. Damage caused by contaminated hydraulic oil, particle blockage, overpressure shock, incorrect installation and human damage is not covered by warranty.

Q4: How to prolong the service life of the fan motor?
A4: Fully flush the hydraulic pipeline and replace new hydraulic filters before installation to remove dirt and debris. Inspect spline shaft, sealing rings and mounting bracket for wear. Complete no-load test run after installation, check noise, torque and temperature rise, then put into heavy-duty operation only after confirmation.
