JLG 1001257281 Spark Arresting Muffler Assembly

The JLG 1001257281 is a spark arresting muffler assembly engineered for integration with Deutz D2011 series diesel engines installed in JLG rough terrain scissor lifts and telescopic boom lifts. This component functions as a critical element of the exhaust and emissions system, attenuating engine noise and preventing the discharge of incendiary particles in hazardous or regulated environments. Constructed from high-temperature aluminized steel or stainless steel, the unit features a baffled internal geometry optimized for backpressure management compatible with the D2011 power curve. It serves as a direct replacement for Deutz DTZ part number 3220103. Application coverage spans JLG 600 Series (600A, 600AJ, 600S, 600SJ) and 800 Series (800A, 800AJ, 800S, 860SJ, 660SJ) aerial work platforms. Installation utilizes existing OEM mounting brackets and exhaust flange interfaces.
