Question 1

What does an undersize bearing do?

Accepted Answer

Undersize bearings are used when the crankshaft has been machined smaller than its original factory size. Using an undersize bearing restores the proper oil clearance between the rod and the crank.

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 need to be machined. The machine shop will then specify the correct undersize for the bearings.

Question 3

What happens if I use the wrong size bearing?

Accepted Answer

Using the wrong size bearing can cause serious engine damage. If the bearing is too small, there won't be enough oil clearance, leading to friction and potential seizure. If the bearing is too large, there will be excessive oil clearance, resulting in low oil pressure and potential engine knock.
