* Main bearings: The main bearings are the bearings that support the crankshaft in the engine block. They are located at each end of the crankshaft and help to keep it in place.
* Thrust bearings: The thrust bearings are special bearings that are designed to absorb the axial forces that are created by the combustion of fuel in the engine. They are located at the front and rear of the crankshaft and help to prevent it from moving forward or backward.
* Crankshaft end seals: The crankshaft end seals are seals that are located at the front and rear of the crankshaft. They help to prevent oil from leaking out of the engine.
These components work together to keep the crankshaft in place and prevent it from moving forward or backward. This is important because if the crankshaft were to move, it could cause damage to the engine.
