What does the 'P30' in the part number MS1432P30 signify?

The 'P' in the part number typically indicates the bearing material composition, while the '30' signifies that this is a 0.030 inch undersize bearing set. This means the bearings are designed for a crankshaft that has been machined down by 0.030 inches.

What is the purpose 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 that allows the crankshaft to rotate smoothly while maintaining precise oil clearance, which is essential for engine health and performance.

Do I need to purchase anything else with this main bearing set for an engine rebuild?

For a complete engine rebuild, you will typically need a full set of engine bearings, including connecting rod bearings, and often a new oil pump and oil filter. It's also recommended to have the crankshaft professionally measured and cleaned before installing new bearings.

This Clevite main bearing set is built to the 0.030 inch undersize specification, meaning it's designed to work with crankshafts that have been machined down by 0.030 inches. This is a common requirement when rebuilding an engine where the main journals have wear beyond their standard service limits. These bearings are intended for Ford's 351M, 351W, and 400 V8 engines, covering a wide range of applications from 1977 through 1993.

When you're rebuilding an engine, the main bearings are critical for supporting the crankshaft and ensuring it spins smoothly within the block. Clevite uses well-built materials and manufacturing processes to create bearings that can handle the stresses of engine operation. This set is designed to fit right into the specified Ford V8 engines, making your rebuild process more straightforward. Having the correct undersize specification is key to achieving proper oil clearance and ensuring the longevity of your engine build.

This set is suitable for a variety of Ford vehicles including many F-Series trucks, E-Series vans, and Bronco models from the late 70s through the early 90s. Always confirm your specific engine code and year range match the application before ordering.
