What does '0.50mm Oversized' mean for these bearings?

This means the bearings are manufactured to be 0.50mm larger in diameter than standard bearings. They are used when the engine's crankshaft journals have been machined down by 0.50mm to remove wear or damage, restoring the correct oil clearance.

Do these bearings come with installation instructions?

While specific installation instructions are not included, it is critical to refer to the manufacturer's service manual for your 1990 Nissan Axxess. Proper installation requires precise torque specifications and ensuring the crankshaft journals are machined to the correct 0.50mm undersize.

What other parts are typically needed for an engine bearing replacement?

When replacing main bearings, it's common practice to also replace rod bearings, piston rings, and all necessary gaskets and seals. It's also essential to have the crankshaft professionally measured and machined to the correct size for the new bearings.

Product Details

Already rebuilt your engine or looking to do a refresh on your 1990 Nissan Axxess? This 0.50mm oversized main bearing set from ACL is a critical component for ensuring proper oil clearance and smooth operation of your KA24E or KA24DE engine. When the crankshaft journals on your engine block wear down, simply replacing them with standard-sized bearings won't be enough. These oversized bearings are designed to compensate for that wear, restoring the correct clearances for optimal lubrication and performance.

ACL is known for making well-built engine bearings, and this set is no exception. They are manufactured to precise tolerances to ensure they fit right and perform reliably. Using the correct undersize or oversize bearing is crucial after a crankshaft has been machined or if you're dealing with worn journals. This 0.50mm size is specific, so make sure your machine shop has prepared your crankshaft to this exact specification before installation.

When you're deep into an engine rebuild, getting the bearing clearances right is paramount. This ACL set is a solid option for getting your KA24 engine back in top shape.
