Question 1

What does '010' mean in the part number?

Accepted Answer

The -010 suffix in the part number indicates that 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 typically used when the crankshaft has been machined.

Question 2

How do I know if I need undersized bearings?

Accepted Answer

If your crankshaft has been machined during an engine rebuild, it may require undersized bearings to maintain the correct oil clearance. A machine shop can measure your crankshaft and recommend the appropriate bearing size.

Question 3

What is the purpose of main bearings?

Accepted Answer

Main bearings support the crankshaft, allowing it to rotate smoothly within the engine block. They maintain a critical oil film between the crankshaft and the block, preventing metal-to-metal contact and reducing wear. Proper bearing selection and installation are essential for engine longevity.
