Question 1

What does 'STD' mean in the product description?

Accepted Answer

STD stands for 'Standard Size.' This bearing set is manufactured to the original factory dimensions, so it will work with a crankshaft that hasn't been machined undersize.

Question 2

What is the bearing clearance?

Accepted Answer

This ACL bearing set provides .001 inch clearance. Bearing clearance is the measured space between the bearing and the crankshaft journal. Proper clearance is critical for oil flow and bearing life.

Question 3

What other parts should I replace when installing new main bearings?

Accepted Answer

When replacing main bearings, it's always a good idea to inspect the crankshaft for wear or damage. Consider replacing the connecting rod bearings at the same time for a complete engine refresh. Refer to the manufacturer's installation instructions for torque specifications and any specific recommendations.
