advantage

- Optimized 41cc medium displacement design, perfectly matched for ZE650 rock crushing heat load
Medium 41cc displacement delivers balanced torque and power consumption, precisely meeting the continuous high heat generation requirement of ZE650 during rock crushing operation without excessive power waste.
- Integrated GC-CSC composite valve module for overload protection and pressure stabilization
Built-in GC-CSC valve assembly realizes pressure overload protection and pressure holding function, effectively suppressing pressure spikes generated during frequent impact of rock crushing and protecting internal gear and bearing components.
- Reinforced heavy-duty bearing set for frequent impact working conditions
Enhanced bearing assembly specially optimized for rock crushing impact loads, reducing bearing fatigue failure risk under repeated shock pressure cycles and extending service life in heavy mine sites.
- Low vibration gear profile reduces radiator core fatigue damage
Refined gear meshing profile cuts down flow ripple and vibration transmission, protecting radiator core and oil pipeline connections under long-time cyclic crushing work.
- Modular oil port configuration, convenient for field maintenance and replacement
Modular oil port layout simplifies on-site disassembly, reduces maintenance time and lowers the risk of pipeline misalignment during replacement.

FAQ

Q1: Which machine does KM30.41L3-KZS3-LMC/MCN-GC-CSC fan motor fit?
A1: This hydraulic fan motor fits Zoomlion ZE650 excavator. Confirm machine serial number before purchase.

Q2: What hydraulic function does this fan motor support?
A2: It provides rotary power for radiator cooling system, dynamically adjusting fan speed to control engine water temperature and hydraulic oil temperature, used for large-scale mine exploitation, hard rock crushing and heavy earthmoving projects.

Q3: What are typical failure symptoms of worn fan motor?
A3: Typical symptoms: insufficient fan torque during rock crushing, fan speed fails to rise under heavy heat load, unstable torque output under impact load, pressure relief function abnormal, sustained high oil temperature during long crushing operation, shaft seal oil leakage.

Q4: What inspections should be done before installing new fan motor?
A4: Inspect matched fan pump, cooling circuit control valve, hydraulic hoses and filter elements. Fully flush hydraulic tank and pipelines 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 motor. Check relief valve calibration, stuck valve spool, clogged filter, damaged seals or trapped air inside hydraulic circuit. Air bleeding must be completed after installation.
