The Multiquip 515663 Muffler Base Extension is a genuine OEM component designed for the AR13D asphalt ride-on roller. Sourced directly from Multiquip, this part matches the original specification for a direct, no-hassle installation on AR13D series equipment. Choosing a genuine OEM part ensures the exhaust system maintains its correct geometry and sealing integrity, keeping the machine operating as it left the factory floor.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original design spec, ensuring correct exhaust outlet positioning, material grade, and dimensional accuracy specific to the muffler base assembly.
- Direct Drop-In Fitment — Designed to bolt up to the existing muffler base on the AR13D using the original mounting points, eliminating guesswork during installation.
- AR13D Roller Compatibility — Confirmed fitment for the Multiquip AR13D asphalt ride-on roller series.
- Exhaust Integrity Maintained — A correctly fitted muffler base extension keeps exhaust gases routed away from the operator and sensitive machine components, preventing heat-related damage to nearby hardware.
- Corrosion-Resistant Durability — Built to withstand the high-heat, high-vibration environment of a compaction roller's exhaust system across extended service cycles.
The muffler base extension serves as the structural and sealing interface between the muffler body and the base mounting point on the exhaust system. It channels exhaust gases safely away from the engine compartment and operator zone while absorbing vibration that would otherwise stress the muffler assembly. When this extension cracks, corrodes, or comes loose, exhaust leaks can develop — exposing the operator to fumes, accelerating wear on surrounding components, and creating noise that signals a service issue. Replacing a worn or damaged 515663 restores proper exhaust routing and protects the integrity of the full muffler assembly on the AR13D roller.
