Yanmar 129436-13500 Muffler Silencer Assembly

The Yanmar 129436-13500 muffler silencer assembly is engineered for the Yanmar 4TNE88 and 4TNV88 series diesel engines. It functions as the primary exhaust noise attenuation device, utilizing internal baffle chambers and expansion volumes to reduce sound pressure levels to meet regulatory standards. Constructed from aluminized steel for corrosion resistance and thermal durability, the unit features flanged or slip-fit inlet and outlet connections matching the OEM exhaust manifold and tailpipe routing. It is a direct replacement for the original equipment muffler installed on Komatsu mini excavators and other machinery powered by the 4TNE88 power unit. The assembly includes integrated mounting brackets for secure chassis attachment, minimizing vibration-induced fatigue failure.
