What does '0.020 inch undersize' mean for these bearings?

This means the bearings are designed to fit a crankshaft that has been machined down by 0.020 inches from its original size. This is common when a crankshaft has been reconditioned.

Why are main bearings important for an engine rebuild?

Main bearings support the crankshaft and allow it to rotate smoothly. Using the correct bearings with the proper oil clearance is crucial for maintaining oil pressure and preventing excessive wear on the crankshaft and bearings.

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

Typically, main bearing sets include the bearings themselves. It is recommended to consult the product packaging or manufacturer's information to confirm if any additional hardware is included, and always refer to your vehicle's service manual for installation procedures.

Product Details

This Clevite Main Bearing Set, part number MS1642P20, is a 0.020 inch undersize set designed for engine rebuilding. Main bearings are critical components that support the crankshaft within the engine block, allowing it to rotate smoothly while handling significant loads. When rebuilding an engine, especially if the crankshaft has been machined undersize, using the correct undersize bearings is essential for proper oil clearance and engine longevity.

Clevite is known for well-built engine components, and this bearing set is no exception. The 0.020 inch undersize specification means these bearings are designed to be used when the crankshaft journals have been ground down by 0.020 inches from their original size. This precise sizing ensures that the gap between the crankshaft and the bearing is within the manufacturer's recommended specifications, which is vital for maintaining adequate oil pressure and lubrication. Proper oil clearance prevents metal-on-metal contact, reducing wear and heat buildup.

Using a reputable brand like Clevite for your main bearings is a solid choice for any engine rebuild. Ensure you have the correct crankshaft journal measurements before ordering to match these 0.020 inch undersize bearings. Always refer to your vehicle's specific service manual for detailed installation procedures and torque specifications.
