Question 1

What does '0.01mm oversized' mean?

Accepted Answer

It means the outside diameter of the bearing is 0.01mm larger than the standard size. This is for engines where the block or crankshaft has been machined, which increases the bearing bore size. Using an oversized bearing restores the proper oil clearance.

Question 2

Do I need to machine my engine block to use these?

Accepted Answer

No, these bearings are designed to compensate for blocks that have already been machined. If your block is standard size, you should use standard-size bearings instead.

Question 3

What happens if I install the wrong size bearings?

Accepted Answer

If the bearings are too small, you'll have excessive oil clearance, which can cause low oil pressure and engine damage. If the bearings are too large, you'll have insufficient oil clearance, which can cause the bearings to overheat and fail.
