FAQ

Q1: What does “0.25” mean in the part number?

A: The “0.25” indicates this is a 0.25mm undersize (OS) bearing. This is used when the crankshaft journal has been ground down by 0.25mm during an engine rebuild. If your crankshaft is at standard size, you need a standard (STD) bearing. Always measure your crankshaft journal diameter before purchasing.

Q2: Is this bearing a direct fit for my Isuzu 4HG1 engine?

A: Yes, this bearing (part number 8-97045801-1) is specifically designed for the 4HG1T engine. However, we always recommend comparing the part number on your old bearing with the one listed here. Also, confirm whether you need standard or undersize bearings based on your crankshaft condition.

Q3: How should I install and maintain these bearings?

A: Installation should be performed by a qualified mechanic. Clean the connecting rod bore and bearing cap thoroughly. Apply clean engine oil to the bearing surface before assembly. Torque the connecting rod bolts to the manufacturer’s specifications (typically 60-70 Nm for 4HG1T). After installation, check the oil pressure and listen for abnormal knocking noises during the first start-up. Regular oil changes with the correct viscosity are essential for bearing life.
