FAQ

Q: How can I be sure this 1136411931 pulley will fit my Hitachi excavator?
A: This part is a genuine OEM component for the Isuzu 6HK1 engine. It will directly fit Hitachi ZX330-3G, ZX350-5G, ZX350H, and ZX350H-3G models that use this engine. We recommend physically checking the part number stamped on your old pulley (1136411931 or 1-13641193-1) to confirm 100% compatibility before purchasing.

Q: What are the signs of a failing water pump pulley on my 6HK1 engine?
A: Common symptoms include a squealing or chirping noise from the front of the engine, visible wobble of the pulley, belt wear or fraying, and engine overheating due to reduced coolant flow. If you notice any of these, inspect the pulley and replace it immediately to prevent damage to the water pump and belt system.

Q: Do I need to replace any other parts when installing this pulley?
A: While the pulley itself is a direct replacement, it is best practice to inspect the water pump bearings for play and replace the serpentine belt if it shows signs of cracking or glazing. This ensures the entire cooling system drive operates smoothly and reliably after installation.
