What is the purpose of main bearings?

Main bearings support the crankshaft within the engine block. They allow the crankshaft to rotate smoothly while maintaining the correct oil clearance, which is crucial for lubrication and preventing wear.

What is the significance of the 'P20' in the part number?

The 'P20' in the part number MS1687P20 typically indicates a specific size or clearance specification for the bearing. In this case, it signifies a 0.020 inch undersize bearing set, meaning it's intended for crankshaft journals that have been machined down by 0.020 inches.

What should I check before installing main bearings?

Before installing main bearings, ensure the crankshaft journals are clean and within the manufacturer's specified tolerances for size and finish. Also, verify that the oil clearance is correct for the application.
