What is the main function of main bearings in an engine?

Main bearings sit between the crankshaft and the engine block. Their primary job is to support the crankshaft, allowing it to rotate smoothly while maintaining the correct oil clearance for lubrication.

Does this main bearing set come with all the necessary parts for installation?

This set includes the main bearings themselves. It's recommended to consult the manufacturer's installation guide for any additional hardware or sealants that may be required for a complete engine rebuild.

What is the significance of the 'A10' in the part number MS1733A10?

The 'A10' typically indicates a specific size or clearance specification for the bearing. In this case, it signifies a 0.010 inch undersize bearing, which is used when the crankshaft journals have been machined down to correct for wear.
