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

The +0.25mm sizing indicates that these bearings are intended for use when the crankshaft journals have been machined down by 0.25mm during an engine rebuild. This ensures proper oil clearance with the undersized journals.

What are these bearings made of?

These main bearings are made with a bimetal construction, featuring an aluminum base. This material choice is common for engine bearings due to its good performance characteristics.

Do I need to machine my crankshaft to use these bearings?

Yes, the +0.25mm sizing means these bearings are designed for a crankshaft that has been machined down by 0.25mm. If your crankshaft is still at standard size, you would need bearings with a different specification.

Product Details

If you're rebuilding the engine in your classic Mercedes-Benz, like a 1963 180D, 1965 190DC, or a 1970 220D, getting the main bearings right is crucial for smooth operation and longevity. This main bearing set from King Engine Bearings is designed to fit a range of Mercedes-Benz models using the M115.926/938/592 or OM611.910 engine codes.

These bearings are constructed with a bimetal aluminum base, which is a common and reliable material for engine bearings. They are precisely sized at +0.25mm, meaning they are intended for use when the crankshaft journals have been machined down by that amount during an engine rebuild. Using the correct size bearing is essential for maintaining proper oil clearance, which is key to preventing premature wear and ensuring the engine runs quietly and efficiently.
