Question 1

What does '0.25' mean in the part number?

Accepted Answer

The '-.25' suffix in the part number indicates this bearing set is 0.25mm or 0.010 inch undersize. This is for crankshafts that have been previously reground, which reduces the rod journal diameter. Using standard-size bearings on a reground crank will result in excessive bearing clearance and low oil pressure.

Question 2

How do I know if I need undersized bearings?

Accepted Answer

If your crankshaft has been reground, it will have smaller diameter rod journals than a factory crank. A machine shop can measure your crankshaft journals and tell you what size bearings you need. Using the wrong size bearings can cause serious engine damage.

Question 3

Are these bearings sold individually or as a set?

Accepted Answer

This ACL part number is a complete set of connecting rod bearings for one engine. It includes enough bearings to do all the connecting rods in the specified Isuzu engine.
