FAQ

Q1: How do I confirm this is the correct main bearing for my Mitsubishi 6D16 engine?
A1: The most reliable method is to cross-reference your engine’s serial number and the existing bearing shell numbers (C621, NDC) removed during teardown. Always measure the crankshaft journal to determine if a standard or undersize bearing is required.

Q2: What is the critical installation tip for these main bearings?
A2> Ensure the bearing shells and engine block saddles are impeccably clean and lubricated with assembly oil during installation. Correct torque sequence and specification for the main bearing caps are absolutely critical to achieve proper clamping force and avoid crankshaft binding or premature failure.

Q3: Do you supply full engine bearing kits for the 6D16?
A3: Yes. We can provide complete bearing overhaul kits including main bearings, connecting rod bearings, and often thrust washers. Contact our sales team with your engine details for a comprehensive kit quotation and faster project completion.
