What does it mean for a bearing to be undersize?

An undersize bearing is manufactured to be slightly smaller than the standard size. This is used when the crankshaft journal has been machined down (ground) to remove imperfections or wear. The undersize bearing compensates for the material removed from the crankshaft, restoring the correct oil clearance.

What is the proper oil clearance for these bearings?

Proper oil clearance is critical for engine lubrication and longevity. You should always refer to the specific service manual for your vehicle's year and model to find the exact oil clearance specifications recommended by the manufacturer.

Does this bearing set come with installation hardware?

This listing is for the crankshaft main bearing set only. It does not include installation hardware or crankshaft bolts. Always refer to the manufacturer's instructions for any additional parts or procedures required for installation.
