Question 1

What does '010' mean in the part number?

Accepted Answer

The -010 suffix in the part number indicates this is a 0.010 inch undersize bearing set. This means the bearing's inner diameter is 0.010 inches smaller than the standard size. Undersized bearings are commonly used when the crankshaft has been ground down during a rebuild.

Question 2

How do I know if I need an undersized bearing?

Accepted Answer

During an engine rebuild, the crankshaft journals are often machined to remove imperfections. If the journals have been ground undersize, standard bearings will result in excessive clearance. A machine shop can measure your crankshaft and recommend the appropriate bearing size to achieve the correct oil clearance.

Question 3

What is the purpose of a connecting rod bearing?

Accepted Answer

Connecting rod bearings sit between the connecting rod and the crankshaft journal, allowing the rod to rotate freely around the crankshaft. They provide a smooth, low-friction surface that protects the crankshaft and connecting rod from wear. Proper bearing clearance is essential for maintaining oil pressure and preventing engine damage.
