Question 1

What happens when connecting rod bearings wear out?

Accepted Answer

As rod bearings wear, the oil clearance increases. This causes a drop in oil pressure, especially at idle. Eventually, the increased clearance leads to a knocking sound as the connecting rod moves excessively on the crankshaft journal.

Question 2

How do I know if I need 0.010" or 0.020" undersized bearings?

Accepted Answer

Undersized bearings are needed when the crankshaft has been machined. When a crankshaft is ground, the rod bearing journals are made smaller, requiring undersized bearings to maintain proper oil clearance. Always measure the crankshaft journal before selecting a bearing size.

Question 3

Are these standard size or undersized bearings?

Accepted Answer

This ACL 4B1950-.25 bearing set is 0.25mm (0.010") undersized. These are commonly used when a crankshaft has been machined.
