Question 1

What does '0.020 inch undersize' mean?

Accepted Answer

When an engine is rebuilt, the crankshaft journals are often machined to remove damage. This makes the journals smaller, so undersized bearings are needed to maintain the correct oil clearance. These bearings are 0.020 inches smaller in diameter than the standard size.

Question 2

What other parts should I replace when replacing the main bearings?

Accepted Answer

It's always a good idea to inspect and/or replace the connecting rod bearings at the same time as the main bearings. Also, check the crankshaft for wear and have it machined if necessary. Refer to the manufacturer's service manual for specific recommendations.

Question 3

How do I install these bearings?

Accepted Answer

Refer to the manufacturer's installation instructions for details. Proper installation is critical for engine longevity. Be sure to use the correct tools and torque specifications.
