Question 1

What does it mean to have an oversized bearing?

Accepted Answer

An oversized bearing is slightly thicker than the standard size. This is useful when a crankshaft has been machined, as it allows for proper oil clearance and bearing crush.

Question 2

How do I know if I need oversized bearings?

Accepted Answer

During an engine rebuild, the crankshaft and connecting rods are often machined. If material is removed, you'll need oversized bearings to maintain the correct clearances. Consult a machine shop to determine the appropriate size.

Question 3

What is plastigage and how is it used?

Accepted Answer

Plastigage is a consumable plastic thread used to measure bearing oil clearance during engine assembly. A small piece is placed between the bearing and crankshaft journal, then the assembly is torqued. When disassembled, the flattened plastigage indicates the oil clearance. Refer to the manufacturer's instructions for proper use.
