What does '.75mm undersize' mean for these bearings?

An undersize bearing is used when the crankshaft journals have been machined down to remove wear or damage. This '.75mm undersize' set is meant for crankshafts that have been ground down by exactly 0.75mm from their original size. Using the correct undersize bearing is crucial for proper oil clearance and engine health.

What is the main function of crankshaft main bearings?

Crankshaft main bearings are essential for supporting the crankshaft as it rotates within the engine block. They create a low-friction surface, reducing wear on both the crankshaft and the block, and maintaining the precise oil clearance needed for lubrication and performance.

Are these bearings sold individually or as a set?

This product is a main bearing set, meaning it includes all the necessary bearings to replace the main bearings for the crankshaft in your compatible Honda or Acura engine.

ACL has been making engine bearings for decades, and this crankshaft main bearing set for your Acura RDX is one of their staples. These bearings are crucial for keeping your engine's crankshaft spinning smoothly within the engine block. They sit between the crankshaft and the engine block, reducing friction and wear on these critical rotating components. This specific set is designed for Honda B16, B17, B18, K20, and K24 engines, covering a wide range of displacements from 1.6L to 2.4L, and fits models from 1990 to 2005.

This set is a .75mm undersize bearing, meaning it's intended for use when the crankshaft journals have been machined down by 0.75mm due to wear or damage. Using the correct undersize bearing is essential for maintaining proper oil clearance and ensuring the longevity of your engine rebuild. ACL bearings are well-built and known for their consistent performance, making them a popular choice for both street and track applications where reliability is key.
