What does the 0.25mm oversize mean for these bearings?

The 0.25mm oversize indicates that these bearings are slightly larger than standard size. This is typically used when the engine's crankshaft journals have been machined down (ground) to a smaller size due to wear or damage during an engine rebuild. These bearings help restore the correct oil clearance.

What type of engine is this bearing set best suited for?

This bearing set features a lead-free composite and bi-metal aluminum construction that is ideal for low to medium-load engines. This design focuses on providing reliable performance without the need for heavy-duty materials often found in high-performance or heavy-duty applications.

Are these bearings environmentally safe?

Yes, these main bearings are made with a lead-free, environmentally safe composite material. This aligns with modern environmental standards for engine components.

About this part

Product Details

These main bearings are built with a lead-free, environmentally safe composite material. This bi-metal aluminum construction is well-suited for low to medium-load engines, like the one in your 1984-1989 Toyota Van. King Engine Bearings has been specializing in bearings since 1960, focusing on supplying well-built engine bearings to the market.

This set is specifically sized at 0.25mm oversize, which is important if you're rebuilding your engine and need to account for previous machining or wear on the crankshaft journals. Using the correct size bearing is crucial for proper oil clearance and engine longevity. King's focus on specialization means they understand the critical role bearings play in engine performance and durability.
