Question 1

What does '0.030 inch undersize' mean?

Accepted Answer

This bearing set is designed for crankshafts that have been machined 0.030 inches smaller than the standard size. This is common during engine rebuilds to correct wear or damage to the crankshaft journals. Using the correct undersize bearing ensures proper oil clearance and prevents engine damage.

Question 2

How do I know if I need undersized bearings?

Accepted Answer

During an engine rebuild, a machinist will measure the crankshaft journals. If the journals are worn or damaged, they may need to be machined to a smaller size. The machinist will then recommend the appropriate undersize bearings to maintain proper oil clearance.

Question 3

What happens if I use the wrong size bearings?

Accepted Answer

Using the wrong size bearings can lead to serious engine damage. If the bearings are too small, there will be excessive clearance, leading to oil pressure loss and potential bearing failure. If the bearings are too large, there will be insufficient clearance, causing the bearings to overheat and seize.
