What is the main purpose of main bearings in an engine?

Main bearings are a critical part of your engine's bottom end. They support the crankshaft within the engine block, allowing it to rotate smoothly while handling the significant forces from the pistons. Proper main bearing function is essential for maintaining oil pressure and engine health.

What does the 'P25MM' in the part number signify?

The 'P25MM' in the part number indicates the specific size of the main bearing. In this case, it refers to the 131.00mm main journal diameter and 158.00mm housing bore, ensuring it's the correct size for the intended application.

Are these bearings sold individually or as a set?

This product is a main bearing set, meaning it includes all the necessary main bearings required for a complete engine rebuild of the specified Mack MP8 or Volvo MD13 engines.
