Question 1

What does '0.025mm oversized' mean?

Accepted Answer

When an engine block is machined, the bearing bores can become slightly larger. An oversized bearing compensates for this extra space, ensuring the correct oil clearance between the bearing and the crankshaft. Always measure your clearances to confirm fitment.

Question 2

Are these bearings compatible with aftermarket crankshafts?

Accepted Answer

These bearings are designed to work with both factory and most aftermarket crankshafts that retain the standard main journal size. However, it's always best to check your clearances to ensure proper fitment, especially with non-standard components.

Question 3

What other parts should I replace when replacing main bearings?

Accepted Answer

When replacing your main bearings, it's best practice to also replace the connecting rod bearings at the same time. You should also inspect the crankshaft for wear and have it machined if necessary. Always use new main cap bolts and torque to the manufacturer's specifications.
