What does the '+0.50mm' sizing mean for these bearings?

The '+0.50mm' indicates that these bearings are intended for use when the engine's crankshaft has been machined down by 0.50mm. This is a common practice during engine rebuilding to ensure proper oil clearance if the original crankshaft journals are worn or have been resurfaced.

What is the advantage of bimetal bearings?

Bimetal bearings, like these from King Engine Bearings, use an aluminum-based alloy. This construction offers good embeddability and conformability, meaning they can adapt to minor imperfections in the crankshaft surface, while still providing the necessary strength for engine operation.

Do these bearings come with installation instructions?

While this set is a direct fit, it is always recommended to refer to the manufacturer's installation instructions or a service manual for the correct procedures, torque specifications, and oil clearance measurements.

Product Details

Built with an aluminum base, this bimetal main bearing set from King Engine Bearings is specifically sized at +0.50mm for the 3Y engine found in the 1984-1989 Toyota Van. Main bearings are critical components that support the crankshaft within the engine block, allowing it to rotate smoothly while handling the immense forces generated during combustion. When rebuilding an engine, especially if the crankshaft has been machined undersize, using bearings with the correct size is essential for proper oil clearance and engine longevity.

King Engine Bearings uses a bimetal construction, which combines the strength of aluminum with other alloys to create a bearing surface that can withstand the demands of engine operation. This particular set is designed to be a direct fit for your Toyota Van's 3Y engine, ensuring that installation is straightforward when the crankshaft has been machined to a +0.50mm undersize. Proper installation and correct oil clearances are key to ensuring these bearings perform as intended and contribute to a healthy, running engine.
