Multiquip 21656 Muffler Assembly 5 Bolt - OEM Replacement Part

This muffler assembly is a critical exhaust component for ride-on power trowels, designed to reduce engine noise and safely direct exhaust gases away from the operator during concrete finishing operations. The 5-bolt mounting configuration ensures secure attachment to the Yanmar 4TNV84T-Z-DSA2 turbocharged diesel engine, which produces 55 hp at 3000 rpm in demanding job site conditions.

During your walk-around inspection and maintenance routine, check the muffler for damage, cracks, or loose mounting bolts. The muffler operates at extremely high temperatures during trowel operation and must be allowed to cool completely before servicing. Failed or damaged mufflers can result in excessive noise, improper exhaust flow, and potential safety hazards for operators working on concrete slabs.

This assembly is engineered specifically for the STXD6i ride-on power trowel, which has an operating weight of 2,165 lbs and is designed for floating and finishing concrete slabs with a 117-inch path width.
