The NTA855 is a model of Cummins diesel engine, and it is part of the NT series. The NT series engines are known for their durability and reliability, commonly used in various applications such as industrial, marine, and automotive.

The front seal in an NTA855 engine refers to the front crankshaft seal, which is a crucial component for preventing oil leaks and maintaining proper lubrication within the engine. The front seal is positioned at the front end of the engine, where the crankshaft extends out of the engine block.

• Function: The front seal serves as a barrier to prevent oil from leaking out of the engine and to keep contaminants from entering. It helps maintain the proper oil pressure within the engine.

• Material: Front seals are typically made from high-quality rubber or synthetic materials that can withstand the harsh conditions within the engine.

• Installation: The front seal is installed at the front of the crankshaft, and it is usually pressed into a specially designed housing in the engine block.

• Replacement: Over time, front seals may wear out due to the constant movement and friction of the crankshaft. When a front seal fails, it can lead to oil leaks, which may result in engine damage. Therefore, timely replacement is essential.

• Maintenance: Regular engine maintenance, including checking for oil leaks and inspecting the condition of seals, is crucial for the proper functioning and longevity of the engine.
