FAQ

Q1: How can I confirm this fan blade will fit my specific Hitachi ZX120?
A1: The most reliable method is to cross-reference your machine’s serial number (S/N) and compare it with the original part number removed from the fan clutch assembly. This part is designed for ZX120/ZAX120 models with the 4BG1 engine. Please contact our technical support with your S/N for pre-dispatch verification.

Q2: Is this a direct bolt-on replacement, or are modifications required?
A2: This is a direct OEM replacement part. It is designed to bolt directly onto the existing fan clutch hub using the standard fasteners. No modifications, drilling, or balancing should be required if the original fan clutch is in good condition.

Q3: What is the recommended inspection routine for this cooling fan blade?
A3: Visually inspect the fan blade for cracks, chips, or significant material erosion during regular engine service intervals (every 500 hours). Check for any loose bolts on the hub. A vibrating fan is a key sign of imbalance or damage and should be replaced immediately to prevent damage to the water pump and surrounding components.
