Description
Overview:
The Gasket (NON-ASB) Engine is a genuine Yanmar part designed for sealing critical joints in Yanmar 3-cylinder diesel engines. Made from durable, non-asbestos composite materials, it provides a tight, reliable seal to help prevent oil, coolant, and combustion gas leaks. This supports stable compression, consistent running, and reduced risk of overheating or contamination. It is engineered specifically for the Yanmar 3TNV88-XTBZ and 3TNV88-BPTB2 models, ensuring a precise fit without modification. Built to handle high temperatures and pressures typical of compact industrial engines, it suits routine maintenance and full overhauls on equipment such as compact excavators, site dumpers, generators, and agricultural or grounds-care machinery. As a genuine OEM component, it matches original specifications for material quality and performance.
Key Features:
