Question 1

What happens if my main bearings wear out?

Accepted Answer

Worn main bearings cause a loss of oil pressure, which can damage other engine components. You may notice a knocking sound from the engine, especially when it's cold. Replacing the bearings can restore proper oil pressure and prevent further damage.

Question 2

How do I know if I need to replace my main bearings?

Accepted Answer

Common signs of worn main bearings include low oil pressure, excessive engine noise (knocking or rumbling), and the presence of metal flakes in the oil. If you experience any of these symptoms, it's best to inspect the bearings and replace them if necessary.

Question 3

Are these standard size or undersized bearings?

Accepted Answer

This ACL part number ends in ".75", indicating that this is a 0.75mm undersize bearing set. These are typically used when the crankshaft has been machined during an engine rebuild. Always measure the crankshaft journals to ensure proper clearance with undersized bearings.
