Question 1

What does '0.25mm oversized' mean?

Accepted Answer

When an engine is rebuilt, the crankshaft journals are often machined to remove damage. This makes the journals slightly smaller. An oversized bearing compensates for this material removal, maintaining the correct oil clearance.

Question 2

Do these bearings come as a complete set for the engine?

Accepted Answer

Yes, this ACL 4B1185A-.25 rod bearing set includes all the bearings needed for a complete engine rebuild. Make sure to check the condition of all bearings during your rebuild.

Question 3

What other parts should I replace when replacing rod bearings?

Accepted Answer

When replacing rod bearings, it's always a good idea to inspect the crankshaft for wear and have it machined if necessary. You should also replace the rod bolts, as they are often torque-to-yield and not reusable.
