FAQ

Q: How do I verify if this bearing set fits my specific Isuzu 4HK1 engine?
A: Confirm the engine model code on your engine data plate. While this set is designed for the standard 4HK1 and 4HF1 engines, variations can exist. We recommend comparing your existing bearing part number (8-94391515-0 or 8-97372076-1) to the ones listed to guarantee compatibility. For further verification, contact our technical support with your engine serial number.

Q: What is the correct installation procedure for these main bearings?
A: Installation requires a clean workspace and precise torque specifications. The bearing shells must be installed dry on the back side into the block and main caps. Apply a thin layer of clean engine oil to the bearing surface before installing the crankshaft. Always use a torque wrench to tighten main cap bolts to the manufacturer’s specified torque in the correct sequence. A service manual for the 4HK1 engine is highly recommended. Video technical support is available if needed.

Q: Are these bearings a standard size or undersized/oversized?
A: The part numbers 8-94391515-0 and 8-97372076-1 typically refer to standard-size main bearings as supplied by Isuzu for OEM engine builds. If your crankshaft has been ground to an undersize (e.g., 0.25mm or 0.50mm), you will require a corresponding undersized bearing set. Please verify the condition of your crankshaft journal before ordering.
