What does the '+0.75mm' size designation mean for these bearings?

The '+0.75mm' indicates that these bearings are 0.75mm undersize. This means they are intended for use when the crankshaft journals have been machined down by 0.75mm during an engine rebuild to correct wear or damage.

What is the advantage of a bimetal bearing with an aluminum base?

Bimetal bearings with an aluminum base offer a good balance of strength and conformability. The aluminum provides a solid foundation, while the bearing surface is designed to manage loads and reduce friction effectively within the engine.

Are these bearings sold individually or as a set?

This product is a connecting rod bearing set, meaning it includes all the necessary bearings for the connecting rods in the specified engine application.

Product Details

These connecting rod bearings are built with a bimetal construction, featuring an aluminum base. This design is specifically for the Honda C27A4 engine, and this set is sized 0.75mm undersize, meaning it's intended for crankshaft journals that have been machined down by that amount during an engine rebuild. They are designed to fit the 1986-1990 Acura Legend, as well as certain Honda Accord and Sterling models from the late 80s and early 90s.

King Engine Bearings uses this bimetal approach to offer a solid option for engine rebuilding. The aluminum base provides a good foundation for the bearing surface, helping to manage loads and reduce friction within the engine. When you're rebuilding the bottom end of your engine, properly sized and well-built bearings like these are crucial for ensuring proper oil clearance and long-term durability.
