The conical disc with code K 21005 is an essential pressure-distribution component used with clamping pieces in the engine. Its conical shape helps evenly distribute load forces across the contact surface, reducing localized stress and enhancing mechanical stability. By improving the connection between fasteners and structural elements, this disc plays a crucial role in minimizing fatigue and prolonging the life of the engine’s critical joints.
The bolt identified as K 21002 plays a vital role in securing the clamping pieces that hold key engine components in place. Engineered for high strength and vibration resistance, this bolt withstands substantial mechanical loads during operation. Its precise threading and high-grade material ensure reliable fastening, making it indispensable for maintaining structural integrity and alignment throughout the engine’s working life.
The O‑ring with code K 21404 is a critical sealing element designed for the cylinder liner of the engine. Its primary function is to provide a leak‑proof barrier between the liner and engine block, preventing coolant and combustion gases from mixing. This component endures high temperatures and pressures, maintaining its integrity even under intense thermal cycling. A properly functioning O‑ring is essential for preserving compression and ensuring optimal engine performance over long operational periods.
This round seal ring provides reliable sealing at various joints within the MAN L21/31 engine. Designed to resist pressure and wear, it ensures leak-free operation and helps extend component life through stable and clean sealing.
The tie rod ensures a secure connection between the cylinder head and crankcase. In the MAN L21/31 engine, it plays a vital role in distributing internal forces evenly, preventing deformation, and maintaining engine integrity under heavy-duty conditions.
The seal ring M20X26 is a small yet essential component in the MAN L21/31 engine, used to maintain fluid-tight connections in high-pressure and high-temperature environments. It prevents leaks, supports engine cleanliness, and contributes to long-term performance and efficiency.
