What does the +0.25mm size mean for these bearings?

The +0.25mm designation indicates that these bearings are 0.25 millimeters larger than standard size. This is used when the crankshaft journals have been machined down by 0.25mm during an engine rebuild to ensure a proper fit and correct oil clearance.

What is the construction of these main bearings?

These main bearings feature a bimetal construction with an aluminum base. This design helps with heat dissipation and provides a durable surface for the crankshaft to rotate against.

Do I need to machine my crankshaft to use these bearings?

Yes, the +0.25mm size means these bearings are intended for use with a crankshaft that has been professionally machined down by 0.25mm. Using oversize bearings on a standard-size crankshaft will result in incorrect oil clearance and potential engine damage.
