M-2110587 | Main Bearing - C10, C12, C13

Diesel engine main bearings are components that support the crankshaft and provide a smooth and friction-free rotation. The main bearings are located in the engine block and are the primary support for the crankshaft. The bearings reduce friction, wear, and tear on the crankshaft, and ensure that it rotates smoothly and accurately. 

 

The main bearings are typically made of steel or bronze and are coated with a thin layer of a high-temperature lubricant to ensure smooth operation. They are designed to last for a long time, but over time, due to wear and tear, they may need to be replaced.

 

The main bearings should be replaced if there is any damage or wear on them, which can cause vibrations, noise, and other engine problems. Signs of damage or wear on the main bearings include knocking or tapping sounds from the engine, low oil pressure, and increased engine vibration.

 

Thrust washers are also an important component of the engine's main bearings. They are designed to provide axial support for the crankshaft and prevent it from moving forward and backward. Thrust washers are typically made of steel or bronze, and they also need to be replaced if they are worn or damaged.
