FAQ

Q: How do I confirm these bearings fit my Isuzu 4JK1 engine?
A: Check the original part number stamped on your old bearing or your engine’s service manual. If it matches 8-97388735-0 (main) or 8-97388921-2 (rod), these are the correct parts. These are standard size bearings; if your crankshaft has been previously ground, you may require an undersized bearing.

Q: What is the recommended installation procedure?
A: Installation should be performed by a qualified diesel mechanic. Key steps include: 1) Cleaning the bearing saddles and caps thoroughly. 2) Applying clean engine oil to the bearing surface. 3) Torquing the main and rod cap bolts to the manufacturer’s specifications using a calibrated torque wrench. 4) Checking bearing clearance with Plastigauge to ensure it is within the service manual range.

Q: What is the shelf life of these bearings?
A: When stored in a cool, dry environment and kept in the original packaging to prevent contamination, these bearings have an indefinite shelf life. The protective anti-corrosion coating will remain effective as long as the packaging is not damaged.
