The Multiquip 12847 Exhaust Gasket 31V is a genuine OEM replacement designed for the HHN31V heavy-duty ride-on power trowel. This part is sourced directly from Multiquip, ensuring an exact match to the original component installed at the factory. The 12847 is the correct specified gasket for the 31V exhaust on HHN31V trowels, so you can order with confidence knowing it will seat and seal correctly the first time. If you are working on an HHN31V and need to address exhaust leaks or are performing a scheduled engine service, this is the part you need.
Key Features
- Genuine OEM Sealing Material — Manufactured to the exact material grade and compression spec required for the 31V exhaust application, delivering a proper seal under sustained engine heat and vibration.
- Direct-Fit Exhaust Replacement — Matches the original bolt pattern and profile of the 31V exhaust port on HHN31V trowels, dropping into place without trimming or modification.
- HHN31V Compatibility Confirmed — Verified fitment for the Multiquip HHN31V heavy-duty 8-foot ride-on mechanical trowel series.
- Prevents Power and Efficiency Loss — A compromised exhaust gasket allows hot gases to escape before the muffler, robbing the engine of back-pressure balance and signaling further exhaust damage if left unaddressed.
- Exhaust Integrity and Operator Safety — A properly sealed exhaust system keeps combustion gases directed away from the operator and prevents heat damage to surrounding engine components.
The exhaust gasket forms an airtight seal between the engine's exhaust port and the exhaust manifold or pipe, containing hot combustion gases and channeling them safely out of the machine. On a ride-on trowel like the HHN31V, the engine runs under sustained load for extended finishing passes, which puts consistent thermal stress on exhaust sealing components. When the gasket fails or burns through, exhaust gases leak at the joint, which can cause audible blowing noises, scorching of nearby components, reduced engine efficiency, and exposure of the operator to exhaust fumes — making timely replacement essential to safe and productive operation.
