What does 'oversized' mean for these bearings?

Oversized bearings are thicker than standard bearings. This set is 1.00mm oversized, meaning it's designed for use when the crankshaft journals have been machined down by 1.00mm. This ensures the correct oil clearance is maintained in a rebuilt engine.

What is the purpose of main bearings?

Main bearings support the crankshaft within the engine block. They allow the crankshaft to rotate smoothly while bearing the load of the rotating assembly. Proper lubrication and correct bearing size are crucial for engine longevity.

Do I need to measure my crankshaft journals?

Yes, it is critical to measure your crankshaft journals after machining to determine the correct bearing size. This set is 1.00mm oversized; if your journals are not machined to this specific size, you will need a different bearing set to ensure proper oil clearance.

Product Details

You get a full set of main bearings in this kit, which means one box handles the whole engine rebuild. These ACL main bearings are designed for your 1990 Nissan Axxess with the KA24E or KA24DE engine. Main bearings are critical components that sit between the crankshaft and the engine block, allowing the crankshaft to spin smoothly while supporting its weight. When you're rebuilding an engine, especially if the crankshaft has been machined, using the correct size bearings is essential for proper oil clearance and long-term engine health.

This set is specifically 1.00mm oversized, meaning it's intended for use when the crankshaft journals have been ground down by 1.00mm. Using the correct oversized bearing ensures you maintain the proper oil clearance, which is vital for lubrication and preventing premature wear. ACL is a well-known name in engine bearings, and this set is a solid option for anyone undertaking an engine overhaul. They are well-built to handle the demands of a rebuilt engine.
