Question 1

What does '0.060 undersize' mean?

Accepted Answer

An undersized bearing is designed for crankshafts that have been machined smaller than the original factory specification. This is often done during engine rebuilding to correct wear or damage. Using the correct undersize bearing ensures proper oil clearance and prevents engine damage.

Question 2

How do I know if I need undersized bearings?

Accepted Answer

You'll need to measure your crankshaft's main bearing journal diameters after it has been machined. Your machinist will be able to tell you the correct undersize needed to achieve the proper oil clearance. Always refer to the engine manufacturer's specifications for the correct oil clearance range.

Question 3

What happens if I use the wrong size bearings?

Accepted Answer

Using bearings that are too small (oversized) will result in excessive oil clearance, leading to low oil pressure and potential engine damage. Bearings that are too large (undersized) will cause insufficient oil clearance, which can cause the bearing to overheat and seize.
