Question 1

What does 'undersize' mean?

Accepted Answer

An undersize bearing is slightly thinner than the standard size. These are used when the crankshaft has been machined (ground) to a smaller diameter, usually to repair damage. Using an undersize bearing restores the proper oil clearance.

Question 2

How do I know if I need undersize bearings?

Accepted Answer

During an engine rebuild, a machine shop will inspect the crankshaft. If the crankshaft journals are worn or damaged, they may grind them down to a smaller, uniform size. The machine shop will then specify the correct undersize for the bearings.

Question 3

What happens if I use the wrong size bearings?

Accepted Answer

Using the wrong size bearings can lead to either excessive or insufficient oil clearance. Too much clearance results in low oil pressure and potential engine damage. Too little clearance can cause the bearing to overheat and seize.
