600-625-7550 Excavator cooling parts fan blade for Komatsu 4D102

600-625-7550 Cooling Fan Blade for Komatsu PC120-6 4D102

The 600-625-7550 / 6006257550 cooling fan blade is used for Komatsu excavator engine cooling system applications. It is commonly referenced for PC120-6 machines with 4D102 / S4D102E engine references.

This fan blade should be checked by physical specification before ordering. Machine model alone is not enough, because cooling fan blades may differ in diameter, blade count, center hub, mounting hole pattern, offset and rotation direction.

Part Number and Search Formats

Common part number formats include 600-625-7550 and 6006257550. Some public listings also associate this fan with Komatsu PC100-6, PC120-6, PC130-6, PC128US and PC128UU model references.

Other Komatsu fan blade numbers, such as 600-625-0520, 600-625-6560, 600-625-7620, 600-635-7850 or YM129612-44740, should be treated as separate products unless the old fan blade and parts reference confirm the same specification.

Application Reference

Main model reference: Komatsu PC120-6. Additional public references may include PC100-6, PC130-6, PC128US-1, PC128US-2, PC128UU-1 and PC128UU-2. Final fitment should be verified by old fan blade dimensions and machine serial number.

Before Ordering, Check These Points

• Outer diameter: measure the full fan blade diameter.

• Blade count: confirm the number of blades and blade direction.

• Mounting holes: compare hole count, hole spacing and bolt pattern.

• Hub size: check center hole diameter and mounting surface.

• Offset: confirm the distance between the fan mounting face and blade position.

• Rotation direction: check airflow direction before installation.

Common Replacement Reasons

• Overheating: weak airflow can contribute to high coolant temperature.

• Cracked blade: cracks or missing blade sections can reduce cooling efficiency.

• Vibration: fan imbalance, wrong blade specification or loose mounting bolts may cause vibration.

• Radiator contact: incorrect diameter or offset may cause fan-to-shroud or fan-to-radiator interference.

• Abnormal noise: damaged blade edges or poor clearance should be checked before operation.

Installation Notes

• Stop the engine and allow the cooling system to cool before removal.

• Inspect the fan hub, pulley, fan belt and mounting bolts before installing the replacement blade.

• Do not install the fan if the center hole, bolt pattern, offset or rotation direction is different from the old part.

• Tighten bolts evenly according to the machine service procedure.

• After installation, run the engine at low speed and check for vibration, noise, airflow direction and fan shroud clearance.

Photos Needed for Confirmation

Please send the machine model, serial number, old fan blade part number, full fan photo, hub photo, mounting hole photo, measured diameter and rotation direction before quotation.
