FAQ

Q: How do I determine which undersize bearing I need for my engine rebuild?
A: The correct undersize (0.25, 0.5, 0.75) is determined by the amount of material removed from the crankshaft journals during the regrinding/machining process. Always refer to the machinist’s specifications or measure the final journal diameter to select the corresponding bearing size that restores the proper oil clearance.

Q: Is this a complete set of main bearings for one engine?
A> Yes, this listing is for a complete main bearing set, which includes all required bearings for the main bearing caps along the entire length of the crankshaft for one 6HK1 or 6HH1 engine.

Q: Are these bearings suitable for high-mileage or performance applications?
A> Absolutely. As genuine-specification components, they are engineered to handle the standard and high-stress loads of commercial and industrial use. For performance applications, ensuring proper installation with verified clearances is critical for durability.
