What does the +0.25mm sizing mean for these bearings?

The +0.25mm sizing indicates that these bearings are slightly larger than standard. This is typically used when the crankshaft journals have been machined down by 0.25mm, or when a specific, slightly larger oil clearance is desired during an engine rebuild.

What is the purpose of main bearings in an engine?

Main bearings support the crankshaft in the engine block. They create a low-friction surface for the crankshaft to rotate within, maintaining the correct oil clearance to ensure proper lubrication and prevent excessive wear.

Does this set include all the main bearings needed for the engine?

This specific set includes the #1, #3, and #5 main bearings. Depending on your engine's configuration, you may need additional bearing sets for the other positions.
