A. main journals.
The crankshaft is a crucial component of an internal combustion engine, converting the linear motion of the pistons into rotational motion that eventually turns the wheels of the vehicle. Main journals are the parts of the crankshaft that rest and rotate within the engine block. They are supported by bearings or bearing inserts, which provide a smooth surface for the main journals to rotate on while minimizing friction and wear. The bearings are typically made of a softer material than the crankshaft to ensure that any wear occurs on the bearings instead of the crankshaft itself.
