• **Custom heavy-duty design exclusively for Volvo EC950E, perfectly matched with proportional fan pump**
14673696 hydraulic piston fan motor is tailor-made for Volvo EC950E large excavator. It works synchronously with supporting proportional fan pump. Fan rotation speed automatically adjusts following engine coolant temperature, matching heavy-load heat generation and effectively solving overheating risks under continuous heavy-duty working conditions.
• **Excellent low-speed torque performance & stable operation, reduced internal leakage**
Precision ground piston, valve plate and cam assembly. Optimized clearance and sealing structure. Deliver strong torque at low rotating speed, guarantee stable fan operation. Low volumetric leakage reduces energy loss and improves cooling efficiency.
• **High-strength ductile iron housing, outstanding shock & vibration resistance**
Ductile iron shell treated by stress relief annealing to eliminate residual internal stress. Strong impact resistance and vibration resistance, suitable for long-term operation in mining and quarry sites. Less shell deformation and slower wear of internal components for longer service life.
• **Real-time intelligent cooling regulation to protect core engine components**
Proportional hydraulic control realizes intelligent cooling adjustment. It keeps engine and hydraulic components operating within optimal temperature range, avoiding thermal fatigue damage to radiator and engine caused by overheating. It is the premium replacement part for Volvo EC950E overhaul and daily maintenance.

FAQ 

Q1: Which machine model does 14673696 fan motor fit? Can it be used on other Volvo excavators?
A1: Part 14673696 fan motor is specially designed for Volvo EC950E large excavator. It belongs to the cooling hydraulic system and cannot be universally used for other excavator models. It must be paired with the corresponding proportional fan pump. Wrong selection will lead to insufficient fan power and machine overheating.

Q2: What tests will be carried out before delivery?
A2: Every fan motor undergoes complete hydraulic bench tests before shipment, including torque characteristic test, variable speed test, burst pressure test and internal leakage inspection. Strict quality control ensures stable performance in tough site conditions. Test reports can be provided upon customer request.

Q3: What points need attention during installation and commissioning?
A3: Direct replacement without modification. After installation, bleed air from the cooling hydraulic circuit and confirm motor rotation direction. If the machine still overheats after startup, check the cleanliness of hydraulic oil and the signal of proportional solenoid valve on the matched fan pump.
