Question 1

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

Accepted Answer

Worn main bearings increase the clearance between the crankshaft and the engine block. This leads to a drop in oil pressure, which can cause serious engine damage due to lack of lubrication. Replacing the bearings restores proper oil pressure and protects your engine.

Question 2

Are these standard size or undersized bearings?

Accepted Answer

This ACL bearing set is 0.25mm / 0.010 inch undersize. Undersized bearings are used when the crankshaft has been machined, to compensate for the material removed during the machining process and maintain proper oil clearance.

Question 3

What else should I replace when replacing main bearings?

Accepted Answer

When replacing main bearings, it's best practice to also replace the connecting rod bearings at the same time. It's also a good idea to inspect the crankshaft for wear and have it machined if necessary. Refer to the manufacturer's service manual for torque specifications and any other specific instructions.
