Question 1

What does '0.25 oversized' mean?

Accepted Answer

The term '0.25 oversized' refers to the bearing's dimensions. These bearings are 0.25mm (approximately 0.010 inch) larger than the standard size, intended for use in engines where the crankshaft or engine block has been machined. Using oversized bearings ensures proper oil clearance and crankshaft support in modified engines.

Question 2

Are these bearings suitable for a stock engine?

Accepted Answer

These oversized bearings are specifically designed for engines that have undergone machining, such as align boring or honing. Using them in a stock engine without the necessary modifications can lead to improper oil clearance and potential engine damage. Always consult with a professional machinist to determine the correct bearing size for your specific engine.

Question 3

What other parts should I replace when installing new main bearings?

Accepted Answer

When replacing main bearings, it's best practice to also inspect and, if necessary, replace the connecting rod bearings at the same time. Additionally, consider replacing the main bearing bolts or studs, as they may stretch over time and lose their clamping force. Refer to the manufacturer's recommendations for torque specifications and any specific installation procedures.
