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

The '+1.0mm' indicates that these bearings are 1.0 millimeter larger in diameter than standard size. This is used when the crankshaft journals have been machined undersize during an engine rebuild to account for wear. Always measure your crankshaft journals to ensure you order the correct bearing size.

What is the advantage of bimetal bearings?

Bimetal bearings, like these with an aluminum base, offer good heat transfer properties and a strong bearing surface. This construction helps to manage the heat generated during engine operation and provides a reliable surface for the crankshaft to rotate against, supported by oil.

Does this main bearing set include everything needed for installation?

This product is a set of main bearings only. You will need to ensure you have the correct engine oil and potentially other related engine components, such as seals or gaskets, which are typically sold separately, to complete the engine assembly.

About this part

Product Details

This is a King Engine Bearings Main Bearing Set, specifically for the 3Y engine found in the 1984-1989 Toyota Van. Main bearings are crucial components that support the crankshaft within the engine block, allowing it to rotate smoothly while handling immense forces. When rebuilding or repairing your engine, using a well-made set of bearings like these is essential for proper oil clearance and long-term durability.

These bearings are constructed with a bimetal design, meaning they have an aluminum base. This material choice helps with heat dissipation and provides a good surface for the crankshaft to ride on, ensuring consistent oil film support. This particular set is sized at +1.0mm, which is important to note if your crankshaft has been machined undersize during a previous rebuild or repair. Always confirm your crankshaft journal size before ordering bearings.

Using the correct size and type of main bearings is key to a healthy engine. King Engine Bearings is a well-known name in engine components, and this set is designed to meet the needs of your Toyota Van's 3Y engine.
