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

Main bearings support the crankshaft within the engine block. They create a low-friction surface for the crankshaft to rotate on, while also maintaining the correct oil clearance to ensure proper lubrication and oil pressure.

What does the 'H026MM' in the part number signify?

The 'H026MM' typically indicates the specific size of the bearing. In this case, it refers to a 0.026 inch undersize bearing set, which is used when the crankshaft journals have been machined undersize during a rebuild.

Are these bearings sold individually or as a set?

This part number, MS1802H026MM, represents a complete set of main bearings needed for one engine rebuild. You will receive all the necessary bearings to replace the main bearings on your crankshaft.

Product Details

If you're rebuilding the bottom end of your engine, a solid set of main bearings is crucial. This Clevite MS1802H026MM main bearing set is built to replace the worn ones in a range of vehicles, including models like the Mazda Miata, Ford Escort, and Kia Sephia. These bearings are key to keeping your crankshaft spinning smoothly within the engine block, and replacing them during an engine overhaul is standard practice to ensure proper oil clearance and long life.

Clevite uses a multi-layer bearing construction with a steel backing for strength and a babbit overlay for excellent conformability and embeddability, which helps them handle minor imperfections in the crankshaft journal. This design helps maintain consistent oil pressure and reduces friction, which is essential for engine health. They are a popular choice for engine rebuilds because they offer reliable performance and fit right into the factory main caps.

When you're putting an engine back together, getting the main bearings right is important. This set is designed to meet the original specifications for oil clearance, ensuring your rebuilt engine runs as it should. Make sure to follow the manufacturer's instructions for cleaning the crankshaft journals and main caps, and use the correct torque specifications when installing the main caps.
