Question 1

What does '0.25mm oversized' mean?

Accepted Answer

If your crankshaft has been ground down during a rebuild, the rod journal will be slightly smaller than its original size. These 0.25mm oversized bearings compensate for that material removal, ensuring the proper oil clearance between the bearing and the crankshaft.

Question 2

Are these bearings compatible with aftermarket connecting rods?

Accepted Answer

These bearings are designed to fit standard-sized connecting rods for the B58 engine. If you're using aftermarket rods, confirm that they are designed to work with standard-sized bearings. Always check clearances during engine assembly to ensure proper fitment.

Question 3

What else should I replace when replacing my rod bearings?

Accepted Answer

When replacing your rod bearings, it's always a good idea to inspect the crankshaft for wear and 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 torque specifications and any other recommendations.
