What is the purpose of main bearings in an engine?

Main bearings support the crankshaft within the engine block. They create a low-friction surface that allows the crankshaft to rotate smoothly while maintaining the correct oil clearance, which is essential for lubrication and preventing wear.

What does 'MS1732M' signify in the part number?

The 'M' in the part number typically indicates that these are main bearings. The preceding numbers are specific to Clevite's internal cataloging for this particular application and size.

Are these bearings available in different sizes for engine rebuilding?

While this specific part number MS1732M is for a standard size, Clevite often offers main bearing sets in various undersizes (e.g., -010, -020) for crankshafts that have been machined during an engine rebuild. Always verify the correct size needed for your specific engine build.
