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

Main bearings are crucial components that support the crankshaft within the engine block. They create a low-friction surface for the crankshaft to rotate on and help maintain the precise oil clearance needed for proper lubrication and engine operation.

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

This set includes the main bearings themselves. You will typically need to purchase a separate main bearing cap bolt set and ensure you have the correct assembly lube as recommended by Clevite for proper installation.

What is the significance of the 'H20' in the part number MS804H20?

The 'H' in the part number often indicates a specific type of bearing material or construction, while the '20' typically signifies a 0.020 inch undersize. This means the bearings are designed for crankshafts that have been machined down by 0.020 inches during a rebuild.
