FAQ

Q: How do I confirm these bearings fit my engine?

A: The most reliable method is to check the OEM part number stamped on your old bearing shell. If it matches 1-11510093-3 (for the main bearing) or 1-12271072-1 (for the connecting rod bearing), this set is a direct fit. You should also verify that your engine block and crankshaft are machined for standard-size bearings.

Q: What is the correct installation procedure for these bearings?

A: Installation should be performed by a qualified diesel mechanic. Key steps include: 1) Thoroughly cleaning the bearing bore and crankshaft journal. 2) Checking the oil clearance using Plastigage to ensure it falls within the manufacturer’s specification (typically 0.03mm to 0.08mm for used journals). 3) Applying clean engine oil to the bearing surface during assembly. 4) Torquing the main bearing and connecting rod caps to the correct specification in the proper sequence.

Q: Do these bearings require any special maintenance after installation?

A: No special maintenance is required beyond standard engine care. After initial installation, it is critical to prime the oil system by cranking the engine with the fuel cut-off until the oil pressure light goes out. We also recommend an oil and filter change after the first 50 hours of operation to remove any fine debris from the break-in process. Always use the correct viscosity grade of engine oil as specified by Isuzu for the 6WA1 engine.
