FAQ

Q1: How do I confirm this crankshaft will fit my specific Isuzu engine?
A1: The most reliable method is to cross-reference the OEM part number stamped on your original crankshaft or listed in your engine’s official parts catalog with the numbers provided in our OEM Cross-Reference section. Providing your engine model, serial number, and chassis number (if for a vehicle) allows us to offer final verification before shipment.

Q2: Is any additional machining or balancing required upon installation?
A2: No. This crankshaft is supplied as a fully finished, ready-to-install component. It has been precision machined and dynamically balanced to OEM specifications. However, as a best practice in any engine rebuild, we recommend checking bearing clearances and overall assembly balance with your rotating assembly.

Q3: What is the lead time for orders shipping to [Europe/North America/etc.]?
A3: Lead times vary by destination and shipping method. For standard sea freight to major ports in Europe or North America, typical transit is 25-40 days from shipment.
