King Engine Bearings Nissan Datsun A12/(Size +1.0mm) Main Bearing Set

This is a King Engine Bearings main bearing set for Nissan Datsun A12 engines, specifically sized at +1.0mm. Main bearings are critical components in your engine's bottom end, supporting the crankshaft and allowing it to spin smoothly. If you're rebuilding your A12 engine, whether it's for a classic Datsun 1200, B210, or another compatible model, replacing these bearings is a key step to ensure proper oil clearance and long-term engine health.

These bearings are constructed with a bimetal design, featuring an aluminum base. This construction is chosen for its ability to handle the loads and temperatures within the engine. The +1.0mm sizing indicates these are intended for use when the crankshaft journals have been machined down by 1.0mm during an engine rebuild. Using the correct bearing size is crucial for maintaining the proper oil film between the crankshaft and the bearing, which is essential for lubrication and preventing wear.

This set is designed to fit a range of Nissan Datsun vehicles from the early 1970s through the early 1980s. Ensure you verify fitment for your specific model and year, and always refer to your vehicle's service manual for proper installation procedures and torque specifications when rebuilding your engine.
