description

364-0983 fan motor is the executive component of the independent cooling hydraulic circuit for CAT374F excavator. It receives variable pressurized hydraulic oil from the matched 448-9705 fan pump and converts hydraulic energy into mechanical rotation to drive cooling fan. With built-in reversing valve structure, it can reverse fan airflow periodically to clean dust and debris on radiator surface, reducing manual maintenance frequency. Internal plunger, cylinder block, valve plate and slipper assemblies are made of high-strength alloy steel, processed with precision grinding and surface hardening. The housing adopts stress relief annealing to eliminate casting residual stress, resisting strong vibration and particle contamination in open pit mines. High-performance FKM fluorine rubber sealing assembly provides excellent high temperature resistance and anti-aging property, reducing internal volumetric leakage and external oil seepage. Every motor passes bench test before shipment, including speed response, reversing function and pressure durability test. It is fully interchangeable with original 364-0983, supporting bolt-on installation for excavator overhaul and field repair.

advantage

- Integrated reversing valve design for automatic radiator self-cleaning
Built-in reversing valve allows periodic airflow reversal. It blows dust and debris off radiator core automatically, reducing radiator clog risk and lowering manual cleaning workload in dusty mine sites.
- Stable speed linearity matching electronic proportional fan pump
Precise speed response cooperates with 448-9705 electronic proportional fan pump. Fan speed changes linearly following hydraulic flow variation, avoiding speed hunting under fluctuating thermal load.
- Reinforced bearing assembly for continuous high-speed rotation
Heavy-duty bearing set optimized for long-duration continuous rotation, resisting fatigue wear under 24-hour mine shift operation and extending service life under high temperature.
- Anti-shock internal structure, withstand frequent reversing impact
Internal flow path and valve structure optimized for repeated forward-reverse switching, reducing hydraulic impact during fan reversal and protecting internal friction pairs.
- High torque output at low speed, guaranteeing heat dissipation under heavy digging
Maintains sufficient starting torque under low flow condition, ensuring fan can reach required rotating speed rapidly even when machine starts heavy excavation.

FAQ 

Q1: Which machine does 364-0983 fan motor fit?
A1: This hydraulic fan motor is designed for CAT374F and CAT390F mining excavator with C15 engine, matched with 448-9705 fan pump for cooling circuit. Confirm machine serial number before purchase.

Q2: What is the main function of this fan motor?
A2: It converts hydraulic power into rotation to drive cooling fan. It can rotate forward and reverse periodically to clean radiator, adjust fan speed according to engine temperature to control thermal load.

Q3: What symptoms indicate fan motor failure?
A3: Typical signs: fan cannot reach rated speed, fan fails to reverse, fan stalls under heavy digging, abnormal knocking noise during reversing, internal leakage and shaft seal oil leakage.

Q4: What inspections should be done before installing new fan motor?
A4: Inspect matched fan pump, hydraulic pipeline, pressure relief valve and filter elements. Fully flush cooling hydraulic circuit to remove metal debris. Replace degraded hydraulic oil before assembly.

Q5: Why excavator still overheats after fan motor replacement?
A5: The fault may not come from fan motor. Check fan pump proportional control fault, radiator clogging, sensor failure, blocked filter or trapped air inside cooling circuit. Air bleeding must be completed after installation.
