Question 1

What does '0.25mm oversized' mean?

Accepted Answer

When a crankshaft is damaged, a machine shop can grind it down to a smaller, consistent diameter. This bearing set compensates for that material removal, maintaining the correct oil clearance. Standard-size bearings would be too loose after a crankshaft grind.

Question 2

What other parts are required when replacing rod bearings?

Accepted Answer

At a minimum, you should replace the rod bolts anytime you remove them. Depending on the engine's condition, you might also consider new piston rings, a crankshaft inspection, and an oil pump replacement.

Question 3

How do I know if I need oversized bearings?

Accepted Answer

If your crankshaft has been machined, the shop that did the work should specify the correct bearing size. If you're unsure, consult with a qualified engine builder before ordering.
