Question 1

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

Accepted Answer

The suffix '.25' in the part number 4B8360A-.25 indicates an undersized bearing set. These bearings are 0.25mm smaller than the standard size, designed for crankshafts that have been machined to compensate for wear.

Question 2

How do I know if I need undersized bearings?

Accepted Answer

Undersized bearings are required when the crankshaft has been machined during an engine rebuild. A machine shop will determine the appropriate bearing size based on the amount of material removed from the crankshaft journals. Always follow their recommendations to ensure proper oil clearance and engine performance.

Question 3

What other parts should I replace when replacing the rod bearings?

Accepted Answer

When replacing rod bearings, it's best practice to also inspect and/or replace the connecting rod bolts. Also inspect the crankshaft journals for wear or damage, and consider replacing the main bearings at the same time for a complete engine overhaul.
