What is the difference between standard and oversize bearings?

Standard bearings are for a factory-spec crankshaft. Oversize bearings, like this 1.00mm set, are used when the crankshaft journals have been machined down to remove imperfections or wear. The oversize bearing compensates for the material removed, bringing the clearance back to the correct specification.

Do I need to replace all the connecting rod bearings?

Yes, it is highly recommended to replace all connecting rod bearings as a set during an engine rebuild or refresh. This ensures consistent clearances and wear characteristics across all connecting rod journals.

What else might I need when installing these bearings?

When installing connecting rod bearings, you'll typically need engine assembly lube to properly coat the bearings before installation. It's also crucial to have a torque wrench to tighten the connecting rod caps to the manufacturer's specifications.
