The Multiquip 799797 Exhaust Gasket B46B90 is a genuine OEM exhaust gasket designed for the B46B90 walk-behind power trowel. Sourced directly from Multiquip, this gasket delivers an exact fit to the exhaust port geometry of the B46B90, ensuring a proper seal from day one. If your trowel is showing signs of exhaust leaks — rough idle, unusual noise at the exhaust port, or loss of power — the part is the correct OEM replacement to restore proper operation.
Key Features
- Genuine OEM Sealing Material — Manufactured to Multiquip's original specification, ensuring the gasket material and compression rating match the exhaust port conditions of the B46B90 engine.
- Direct Drop-In Replacement — Matches the original bolt pattern and port dimensions of the B46B90, allowing straightforward installation without trimming or adjustment.
- Confirmed B46B90 Fitment — Engineered specifically for the B46B90 walk-behind power trowel; consult your parts manual to verify applicability to your serial number range.
- Maintains Exhaust Integrity — A properly seated exhaust gasket prevents hot gas leaks that can cause incomplete combustion, rough running, and damage to surrounding engine components.
- Emission and Safety Compliance — Exhaust leaks upstream of emission control components can affect regulatory compliance; using the correct OEM gasket helps keep the machine operating within its designed exhaust parameters.
An exhaust gasket seals the joint between the engine's exhaust port and the exhaust manifold or pipe, preventing hot combustion gases from escaping before they exit through the muffler. On a walk-behind trowel like the B46B90, a failed or compressed-out gasket allows exhaust gases to leak at the cylinder head, which can cause audible ticking or hissing, reduced engine efficiency, and heat damage to nearby wiring or components. Replacing a worn exhaust gasket promptly restores the sealed exhaust path, protecting engine performance and the operator's working environment.
