21060-90069 Cooling Fan Blade for Isuzu 4JB1 Hitachi EX60

The 21060-90069 / 2106090069 cooling fan blade is used for Isuzu 4JB1 engine cooling system applications. It is commonly referenced for Hitachi EX60 and EX60-1 excavators, with additional public references including SH60 and EX75UR series machines.

This fan blade should be selected by the original part number and physical configuration, not by machine model alone. Excavator cooling fan blades may differ in diameter, blade count, center hub, mounting hole pattern, offset and rotation direction.

Part Number and Cross Reference

Common search formats include 21060-90069 and 2106090069. Public supplier references may also list 4353609 as a related cross reference for this fan blade.

Other fan blade numbers such as 600-625-0520, 600-625-7550, 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.

Fitment Reference

Main references include Isuzu 4JB1 engine applications and Hitachi excavator models such as EX60 and EX60-1. Some public references also list EX75UR, EX75UR-3 and EX75URLC-3. SH60 may be used as a market reference when the old fan blade number and physical layout match.

Before Ordering, Check These Points

• Fan diameter: measure the old fan blade from outer edge to outer edge.

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

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

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

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

• Rotation direction: check airflow direction before installation.

Common Replacement Reasons

• Engine overheating: weak airflow may contribute to high coolant temperature.

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

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

• Radiator or shroud contact: wrong fan diameter, offset or mounting position may cause interference.

• Abnormal fan noise: damaged blade edges, poor clearance or loose mounting should be checked.

Installation Notes

• Stop the engine and allow the cooling system to cool before removing the old fan blade.

• Inspect the fan hub, pulley, belt and mounting bolts before installation.

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

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

• After installation, run the engine at low speed and check 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.
