Question 1

What does '20' mean in the part number?

Accepted Answer

The -20 suffix in the part number 8B684P-20 indicates that this is a 0.020 inch undersize bearing set. This means the bearing is slightly smaller than the standard size, useful if your crankshaft has been machined.

Question 2

How do I know if I need undersized bearings?

Accepted Answer

Undersized bearings are typically used when the crankshaft has been machined. A machine shop can measure your crankshaft and advise on the correct bearing size to maintain proper oil clearance.

Question 3

Are these bearings compatible with aftermarket crankshafts?

Accepted Answer

These bearings are designed to fit standard and slightly undersized crankshafts for the specified Olds V8 engines. If you have an aftermarket crankshaft, verify the journal size and bearing requirements with the crankshaft manufacturer to ensure compatibility.
