What does the '0.05' size designation mean for these bearings?

The '0.05' indicates that these are undersize bearings. They are intended for use when the crankshaft's main journals have been machined down by 0.05 inches to correct wear or imperfections.

Are these bearings a direct replacement for the original equipment manufacturer (OEM) bearings?

These are aftermarket bearings designed to meet or exceed OEM specifications for the Mitsubishi 4N15 engine. They are specifically sized at 0.05 undersize, so they are not a direct replacement for standard size OEM bearings.

What is the importance of proper oil clearance with main bearings?

Proper oil clearance is essential for the main bearings to function correctly. It allows a thin film of oil to surround the bearing and crankshaft journal, reducing friction and wear, and ensuring adequate lubrication.
