FAQ

Q: How do I confirm this bearing set fits my Isuzu 4HF1 engine?
A: First, verify your engine model is stamped as “4HF1”. Then, check the part number on your old bearing shell. If it reads 8-97045800-1 or 8970458001, this R801H set is the correct replacement. If the numbers differ, please contact us with your old part number for cross-verification.

Q: What is the installation procedure for these connecting rod bearings?
A: Installation requires precise cleaning of the connecting rod and cap. Ensure the bearing shells are seated dry (no oil on the back) and that the locating tangs engage correctly in the rod and cap grooves. Always torque the rod bolts to the manufacturer’s specification using a calibrated torque wrench. We recommend consulting the Isuzu 4HF1 service manual for exact torque values and procedures.

Q: Can I use these bearings if my crankshaft has been reground?
A: No. These bearings are manufactured for a standard (OEM specification) crankshaft journal size. If your crankshaft has been reground or polished undersize, you will require an undersized bearing set (e.g., 0.25mm or 0.50mm undersize). Using standard bearings on an undersized journal will result in insufficient oil clearance and rapid engine failure.
