Question 1

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

Accepted Answer

The "-.25" indicates this is a 0.25mm or 0.010 inch undersized bearing set. This means the bearing's inner diameter is slightly smaller than the standard size. Undersized bearings are typically used when the crankshaft has been machined.

Question 2

How do I know if I need to replace my main bearings?

Accepted Answer

Common signs of worn main bearings include a knocking sound from the engine, especially at low RPMs. You might also notice a drop in oil pressure. If you're rebuilding the engine, it's always a good idea to replace the bearings, regardless of their apparent condition.

Question 3

Do these bearings come with installation instructions?

Accepted Answer

Bearing sets typically do not include detailed installation instructions. Refer to the factory service manual or a trusted repair guide for the correct procedure and torque specifications. Proper installation is critical for bearing life.
