Question 1

What does 'thrust in #5 position' mean?

Accepted Answer

The number 5 bearing is designed to handle the crankshaft's thrust load, preventing it from moving back and forth. This ACL bearing set is specifically designed to handle the thrust load in the number 5 position.

Question 2

What does 0.002mm oversized mean?

Accepted Answer

The 0.002mm oversized main bearings are slightly larger than the standard size. These bearings are often used when the engine block has been machined or honed, which can slightly increase the main bearing bore size. Using an oversized bearing ensures proper oil clearance and prevents excessive crankshaft play.

Question 3

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

Accepted Answer

When replacing the main bearings, it's best practice to also replace the connecting rod bearings and check the crankshaft for wear. If the crankshaft is worn or damaged, it may need to be machined or replaced to ensure proper engine operation.
