The Multiquip 20178-001 is a genuine OEM Muffler Heat Shield designed for a wide range of Multiquip mechanical ride-on trowels and masonry saws. This part is a direct OEM replacement sourced from Multiquip, ensuring correct fit across compatible HHN31V and HTN series ride-on trowels as well as MS18, MS20, and MS30 series masonry saws. Verified fitment includes the HHN31VTCSL5, HTO-31VTCSL5, HTN-31VTCSL5, HHN31V, MS18H5.5, MS18H8, MS18E, MS20H, MS20E, MS30H, and MS30E. Sourcing the correct OEM heat shield means no guesswork on mounting geometry or clearance — this part is built to match the original component exactly.
Key Features
- Genuine OEM Heat Protection: — Manufactured to Multiquip's original specifications, this shield delivers the same thermal barrier performance as the part it replaces, protecting surrounding components from muffler radiant heat.
- Correct Mounting Geometry: — Retains the original bracket pattern and profile for a direct bolt-on installation on all listed trowel and masonry saw models.
- Broad Verified Fitment: — Confirmed for HHN31V, HHN31VTCSL5, HTO-31VTCSL5, HTN-31VTCSL5 ride-on trowels and MS18, MS20, and MS30 series masonry saws.
- Prevents Heat-Related Component Damage: — A properly functioning muffler heat shield keeps exhaust heat away from fuel lines, wiring, and adjacent housings — a failed or missing shield puts those components at risk of heat degradation.
- Operator Safety Compliance: — Heat shields are a required protective component on powered equipment; replacing a damaged or missing shield restores the machine's thermal guarding as originally engineered.
A muffler heat shield is a formed metal guard positioned around or adjacent to the exhaust muffler to redirect and contain radiant heat generated during engine operation. On ride-on trowels and masonry saws, the muffler sits close to fuel system components, wiring harnesses, and operator-adjacent surfaces, making this shield a critical layer of protection. When the shield is cracked, corroded, or missing entirely, nearby components are exposed to sustained high temperatures that can cause premature wear, fuel line degradation, or create a fire hazard — making timely replacement essential for safe and continued operation.
Fits: HHN31VTCSL5, HTO-31VTCSL5, HTN-31VTCSL5, HHN31V, MS18H5.5, MS18H8, MS18E, MS20H, MS20E, MS30H, MS30E. Always verify your model number before ordering. For fitment assistance, contact DHS Equipment.
