What does the +0.75mm sizing mean for these bearings?

The +0.75mm sizing indicates that these bearings are designed for a crankshaft that has been machined down by 0.75mm. This is common during engine rebuilds when the crankshaft journals have been ground undersize to remove wear or damage.

What is the advantage of a bimetal aluminum base bearing?

Bimetal bearings, especially those with an aluminum base, offer good conformability and heat dissipation. This construction helps the bearing adapt to the crankshaft and manage the heat generated during operation, contributing to engine longevity.

Does this main bearing set come with all necessary hardware for installation?

This product is a set of main bearings only. It does not include crankshafts, seals, or other related engine components. Always refer to the manufacturer's installation instructions for a complete list of required parts and procedures.
