FAQ

Q1: How do I confirm this is the correct main bearing for my specific Isuzu 4HK1 engine?
A: The most reliable method is to cross-reference the part number stamped on your original bearing or listed in your engine’s service manual with our primary part number 8973720761. Providing your engine’s serial number can also help us verify compatibility.

Q2: Is this bearing sold as a single piece or as a full set for the engine?
A: This listing is typically for the bearing for one specific journal/cap position. A complete engine overhaul requires a full set of main bearings. Please contact our sales team to confirm the exact quantity provided and to order a complete matched set for your engine rebuild.

Q3: What are the critical installation steps to ensure this bearing’s longevity?
A: Proper installation is crucial. Always clean the bearing saddle and cap thoroughly. Verify the correct oil clearance with Plastigage during assembly.
