FAQ

Q1: How do I confirm this is the correct undersize bearing for my engine?
A: The 0.25mm marking indicates this is an undersize bearing for a reground crankshaft. You must measure your crankshaft journals after machining to confirm the required undersize (e.g., 0.25mm, 0.50mm). This set is specifically for 0.25mm (0.010″) undersize applications on the 6D31 engine. Always consult your engine rebuild specifications.

Q2: Are both the main bearings and connecting rod bearings included in this set?
A: Yes, this product listing is for a complete set that includes both the main bearings (which support the crankshaft in the engine block) and the connecting rod bearings (which connect the rods to the crankshaft) for the Mitsubishi 6D31 engine, all in the 0.25mm undersize.

Q3: What documentation is provided with the shipment for quality verification?
A: We provide a machinery test report as standard documentation. For added assurance, we can arrange a video outgoing-inspection before shipment, allowing you to visually inspect the parts, packaging, and labeling. This is a valued service for B2B buyers ensuring specification compliance.
