Multiquip 515663 Extension Muffler Base - OEM Replacement Part

The muffler base extension provides critical structural support and proper positioning for the exhaust system on Multiquip ride-on rollers. This component ensures the muffler maintains correct clearance from the engine and frame, preventing heat damage to surrounding components while supporting safe exhaust gas routing away from the operator station. Proper muffler mounting is essential for vibration dampening and preventing exhaust system failures during high-vibration compaction operations.

Designed specifically for the AR13D ride-on tandem drum roller, this extension works in conjunction with the Briggs & Stratton DM850D liquid-cooled diesel engine rated at 23.6 hp at 3,600 rpm. The AR13D's compact design with 38.25-inch overall width and articulated steering requires precise exhaust component fitment to maintain the roller's 11.5-inch ground clearance and tight wall clearances of 1.75 inches left and 1.25 inches right. Failed or damaged muffler base extensions can lead to exhaust leaks, improper engine backpressure, and potential contact with hydraulic components or the operator platform.
