What is the purpose of main bearings in an engine?

Main bearings support the crankshaft within the engine block. They create a low-friction surface that allows the crankshaft to rotate smoothly while maintaining precise oil clearance, which is crucial for engine health and performance.

Do these bearings come with new hardware?

This set includes the main bearings themselves. You will need to reuse your original main bearing cap bolts or source new ones separately, as hardware is not typically included with bearing sets.

When should I use standard size bearings?

Standard size bearings are used when the crankshaft journals are still within their original factory specifications and have not been machined undersize due to wear or damage. If your crankshaft has been ground undersize, you would need to purchase undersize bearings instead.

Nissan Axxess 1990

Product Details

Doing an engine rebuild on your 1990 Nissan Axxess? If you're working on the KA24E or KA24DE engine, you'll need a solid set of main bearings. These ACL main bearings are designed to be a direct replacement for your stock bearings, helping to ensure proper crankshaft support and oil clearance during reassembly.

ACL has been making engine bearings for a long time, and these are well-built for the job. They're made to the original equipment specifications, so they fit right in place of your old ones. Getting the right oil clearance is critical for engine longevity, and using standard size bearings like these is the typical approach when the crankshaft hasn't been machined undersize.

When you're putting your engine back together, make sure you have all the necessary components. Cleanliness is key during assembly, so have your shop rags and cleaning supplies ready. Always refer to your vehicle's service manual for the correct installation procedures and torque specifications.
