Question 1

What does the -.25 in the part number signify?

Accepted Answer

The -.25 in the part number 4B8331-.25 indicates that this is a 0.25mm or 0.010 inch undersized bearing set. This means the bearing is slightly smaller than the standard size, which may be needed if the crankshaft has been machined.

Question 2

What other parts should I replace when replacing rod bearings?

Accepted Answer

When replacing your rod bearings, it's always a good idea to inspect the crankshaft for wear or damage. You may also want to replace the rod bolts, as they are often torque-to-yield and not reusable. Refer to the manufacturer's service manual for specific recommendations.

Question 3

Are these bearings compatible with aftermarket connecting rods?

Accepted Answer

These ACL rod bearings are designed to fit standard OEM connecting rods for the specified Mazda engines. If you are using aftermarket connecting rods, you should verify compatibility with the rod manufacturer.
