Question 1

What does '.001mm oversized' mean?

Accepted Answer

The bearing is slightly thicker than the standard size by 0.001mm (one thousandth of a millimeter). This reduces the clearance between the rod and the crankshaft journal. Tighter clearances can be beneficial in high-performance engines to maintain consistent oil pressure.

Question 2

Are these bearings suitable for a stock engine?

Accepted Answer

These bearings can be used in a stock engine during a rebuild. The .001mm oversize will provide slightly tighter oil clearances, which can improve oil pressure and bearing life. However, it's crucial to ensure the crankshaft journals are within the manufacturer's specifications.

Question 3

What other parts should I replace when installing these bearings?

Accepted Answer

When replacing rod bearings, it's always a good idea to inspect the crankshaft journals for wear or damage. Consider replacing the rod bolts as well, as they are often torque-to-yield and should not be reused. Refer to the manufacturer's installation instructions for details.
