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

The '+1.0mm' indicates that these bearings are 1.0mm larger in diameter than standard. They are designed to be used when the connecting rod journals on your engine's crankshaft have been machined down by 1.0mm to remove wear or damage.

What is the material construction of these bearings?

These bearings feature a bimetal construction with an aluminum base. This is a well-built material commonly used in engine bearings for its ability to handle load and heat.

Do these bearings come with new rod bolts?

This product is a set of connecting rod bearings only. New connecting rod bolts are typically sold separately and are recommended for engine rebuilds.

Product Details

If you're rebuilding the engine in your classic BMW, like a 2002 or a 320i, getting the connecting rod bearings right is crucial for long-term health. These King Engine Bearings are specifically made for the BMW M10 engine and are sized 1.0mm oversize, which is important if your crankshaft journals have been machined down during a rebuild.

These bearings use a bimetal construction with an aluminum base, a common and well-built material for modern bearings. This design helps them handle the loads and heat generated by the engine. Because they are a specific oversize, they're intended to be used when the connecting rod journals on the crankshaft have been ground down by 1.0mm to clean up any wear or damage. Using the correct oversize bearing ensures a tight, proper oil clearance, which is vital for preventing premature wear and ensuring the engine runs smoothly.

This set is designed to fit a range of BMW models that use the M10 engine, from the older 1500 and 1800 models to the popular 2002 and the 318i/320i. Make sure to check the fitment details to confirm compatibility with your specific vehicle. When installing, always refer to the manufacturer's service manual for the correct torque specifications and procedures.
