What does the +0.25mm sizing mean for these bearings?

The +0.25mm sizing means these bearings are designed for a crankshaft that has been machined undersize by 0.25mm. This is typically done to correct wear or damage on the crankshaft journals during an engine rebuild.

Why are main bearings important in an engine?

Main bearings are critical for supporting the crankshaft within the engine block. They allow the crankshaft to rotate smoothly while handling the immense forces generated during combustion, and they are essential for maintaining proper oil clearance for lubrication.

Does this bearing set come with installation instructions?

This set includes the main bearings. Always refer to the manufacturer's official service manual or installation guide for detailed instructions, torque specifications, and proper assembly procedures for your specific engine.

About this part

Product Details

This is a main bearing set from King Engine Bearings, specifically sized at +0.25mm for Opel B16Dth, B16Dtj, and B16Dtl engines. Main bearings are crucial components that support the crankshaft within the engine block, allowing it to rotate smoothly while handling significant loads. When rebuilding or repairing an engine, especially if the crankshaft has been machined undersize, using the correct size bearings is essential for proper oil clearance and engine longevity.

King Engine Bearings is known for producing well-built engine bearings. This set is manufactured to precise specifications to ensure it fits correctly and performs reliably. The +0.25mm sizing indicates these bearings are intended for use when the crankshaft journals have been ground down by 0.25mm (approximately 0.010 inches) to remove wear or damage. Using the correct undersize bearing ensures the proper oil clearance is maintained, which is critical for lubrication and preventing premature wear.
