The conical pin, carrying the code H11155, is a small yet indispensable fastening element in the mechanical assemblies of the ASL25 diesel engine. Its tapered shape allows for precise positioning and tight fixation of engine components, minimizing play and enhancing structural integrity. Often used in conjunction with moving parts or high-stress assemblies, the conical pin helps distribute loads evenly and maintain alignment during operation. Despite its modest size, this pin contributes significantly to the mechanical stability and long-term durability of the engine system.
