King Engine Bearings Datsun A12/(Size +0.25mm) Main Bearing Set

Built with a bimetal aluminum base, this main bearing set from King Engine Bearings is designed for Datsun A12 engines. These bearings are crucial for supporting the crankshaft and ensuring it spins smoothly within the engine block. This particular set is 0.25mm undersize, meaning it's intended for crankshafts that have been machined down to compensate for wear.

The bimetal construction offers a good balance of strength and conformability, helping to absorb shock loads and maintain oil film integrity. This makes them a solid option for rebuilding or repairing your A12 engine. They fit a range of Nissan vehicles from the early 1970s through the early 1980s, including models like the Nissan 1200, B210, and 210.

When installing these bearings, it's important to ensure the crankshaft journals are clean and properly machined to the correct undersize. Always refer to the manufacturer's installation instructions for specific details regarding clearances and assembly procedures.
