What does 0.25mm undersize mean for these bearings?

An undersize bearing, like this 0.25mm set, is used when the crankshaft journals have been machined down by that amount. This is typically done to remove wear or damage from the original journals, providing a clean surface for the new bearings to run on.

What is the construction of these King Engine Bearings?

These bearings are made with a bimetal construction, featuring an aluminum base. This material choice is well-suited for the demanding conditions within an engine, balancing load-carrying capacity with thermal properties.

Are these bearings sold individually or as a set?

This product is a set of connecting rod bearings. You will receive the necessary bearings to replace all connecting rod bearings on your engine.

About this part

Product Details

If you're rebuilding the engine in your 1984-1987 Honda Civic, especially with the D13A2 or EV2 engine, new connecting rod bearings are a critical part of the job. These bearings sit between the connecting rod and the crankshaft, allowing the rod to spin smoothly while handling significant loads. Worn bearings can lead to excessive play, knocking noises, and eventually, catastrophic engine failure, so replacing them is a must for a healthy rebuild.

This set from King Engine Bearings uses a bimetal construction with an aluminum base, a common and reliable material for handling the pressures and temperatures found in an engine. The bearings in this specific set are 0.25mm undersize, meaning they are intended for use when the crankshaft journals have been machined down by 0.25mm to clean up wear or damage. This precise sizing ensures a proper fit and oil clearance, which is crucial for lubrication and bearing longevity.
