Question 1

What happens if I don't replace worn crankshaft bearings?

Accepted Answer

Worn crankshaft bearings increase the clearance between the crankshaft and the engine block, causing a drop in oil pressure. Low oil pressure can lead to severe engine damage, including damage to the connecting rod bearings and the crankshaft itself. Replacing the bearings restores proper oil pressure and prevents further damage.

Question 2

How do I know if my crankshaft bearings need replacing?

Accepted Answer

Common signs of worn crankshaft bearings include low oil pressure, especially when the engine is warm. You might also hear a knocking or rumbling sound coming from the engine's bottom end. If you suspect worn bearings, it's best to have a mechanic inspect your engine.

Question 3

Are these standard size or undersized bearings?

Accepted Answer

This ACL bearing set is 0.25mm undersize. Make sure this matches your engine's requirements. Using the wrong size bearing can cause engine damage.
