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

Main bearings support the crankshaft within the engine block. They allow the crankshaft to rotate smoothly while absorbing the significant forces from the pistons and connecting rods during the combustion cycle.

What is the significance of the 'AL' in the part number MS874AL?

The 'AL' typically indicates that these bearings are made from an aluminum-based alloy. This material is chosen for its good bearing properties and compatibility with crankshafts in many engine applications.

What else might I need when installing main bearings?

When installing main bearings, it's essential to use a quality assembly lubricant to protect the bearing surfaces during initial startup. You'll also need the correct torque specifications from the manufacturer's service manual to properly tighten the main bearing caps.
