600-625-0520 Cooling Fan Blade for Komatsu 4D95 Engine

The 600-625-0520 / 6006250520 cooling fan blade is used for Komatsu excavator engine cooling system applications. It is commonly referenced for PC60, PC100 and PC120 series excavators with 4D95 or 4D95L engine references.

This fan blade is not selected by model name alone. Before ordering, the old fan blade should be compared by part number, fan diameter, blade count, hub size, mounting hole pattern, offset and rotation direction.

Part Number and Reference

Common search formats include 600-625-0520 and 6006250520. Some public listings also associate this fan with Komatsu 4D95 / 4D95L engine applications and PC60 / PC100 / PC120 excavator model references.

Other Komatsu fan blade numbers, such as 600-635-7850, 600-635-7870, YM129612-44740, 600-625-7550, 600-625-6560 or 600-625-7620, should be treated as separate products unless confirmed by the old fan blade and parts reference.

Application Notes

Model references may include PC60, PC60-5, PC60-6, PC100-5, PC100-6, PC120-5, PC120-6 and PC120-7. These references are useful for search and initial identification, but final fitment should be checked by physical dimensions and machine serial number.

Buyer Checkpoints Before Ordering

• Fan diameter: measure the old fan blade across the full outer edge.

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

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

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

• Rotation direction: confirm airflow direction before installation.

• Clearance: check fan-to-shroud and fan-to-radiator clearance.

Common Problems Related to Fan Blade Replacement

• High coolant temperature: caused by weak airflow, cracked blades, radiator blockage or belt issues.

• Vibration after installation: often related to blade imbalance, loose bolts or incorrect fan specification.

• Fan shroud contact: may occur if offset, diameter or mounting position is different from the old fan.

• Noise during operation: check blade damage, bolt tightness, pulley alignment and shroud clearance.

Installation Notes

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

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

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

• Tighten mounting bolts evenly according to the machine service procedure.

• Run the engine at low speed after installation and check vibration, noise and airflow direction.

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.
