What does the '+1.0mm' size designation mean for these bearings?

The '+1.0mm' indicates that these bearings are 1.0mm larger in diameter than standard size. This means they are intended for use when the crankshaft journals have been machined down by 1.0mm to remove wear or damage during an engine rebuild.

What is the construction of these main bearings?

These main bearings feature a bimetal construction with an aluminum base. This type of construction is chosen for its good heat dissipation properties and durable bearing surface.

Do I need to purchase anything else with these main bearings?

When rebuilding an engine, it's essential to also replace the engine oil and oil filter. You may also need assembly lube specifically designed for engine bearings to ensure proper lubrication during initial startup.
