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

The '+1.0mm' designation indicates that these bearings are 1.0mm larger in diameter than a standard size bearing. They are used when the engine's crankshaft journals have been machined down by 1.0mm to remove wear or damage, requiring a larger bearing to maintain the correct oil clearance.

What is the construction of these connecting rod bearings?

These bearings feature a bimetal construction, which means they are made of multiple layers. They have an aluminum base, which helps the bearing conform to the crankshaft surface, along with other layers that provide strength and wear resistance.

Are these bearings sold individually or as a set?

This product is a connecting rod bearing set, meaning it includes the necessary bearings to replace all connecting rod bearings on the engine.

Product Details

These connecting rod bearings are made with a bimetal construction, featuring an aluminum base. They are specifically sized at +1.0mm, meaning they are intended for use when the crankshaft journals have been machined down by 1.0mm during an engine rebuild. This set is designed for Daihatsu HC and HD engines, helping to ensure proper oil clearance and smooth operation within the engine's rotating assembly.

King Engine Bearings uses a bimetal design for these rod bearings, which is a common and effective way to handle the loads and temperatures found in an engine. The aluminum base offers good embeddability and conformability, allowing the bearing to adapt to the crankshaft surface, while other layers provide strength and wear resistance. This particular set is a +1.0mm size, which is crucial for engine builders who have had to regrind their crankshaft journals to a larger diameter to clean up wear or damage. Using the correct undersize or oversize bearing is essential for achieving the correct oil clearance, which is vital for bearing longevity and proper engine function.
