Question 1

What does it mean to have oversized bearings?

Accepted Answer

Oversized bearings are used when the crankshaft has been machined smaller than the standard size. This is a common practice in engine building to correct wear or damage. The 0.25mm / 0.010" oversize on these ACL bearings compensates for that material removal.

Question 2

Do I need anything else to install these bearings?

Accepted Answer

You'll need to ensure your crankshaft is properly machined to the correct undersize for these bearings. Refer to the manufacturer's installation instructions for details. You'll also need assembly lube to properly install the bearings.

Question 3

What if I need standard-size bearings?

Accepted Answer

These bearings are 0.25mm / 0.010" oversized. If your crankshaft is still at the standard factory size, you'll need to order the standard-size ACL main bearings for your engine.
