What is the size of these main bearings?

These main bearings are 0.040 inches undersize. This means they are slightly smaller than the standard size, which is typically used when the crankshaft journals have been machined down to correct for wear.

What does 'bimetal' construction mean for these bearings?

Bimetal construction, in this case with an aluminum base, refers to the layered materials used to create the bearing surface. This design is chosen for its ability to handle engine loads and provide good wear characteristics.

Do I need to purchase anything else to install these bearings?

When rebuilding an engine, it's recommended to also have new crankshaft thrust bearings, oil seals, and a fresh supply of engine oil. Always refer to the manufacturer's service manual for a complete list of required parts and procedures.
