The Multiquip 797770 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 the first installation. If you are servicing or rebuilding the exhaust system on your B46B90 trowel, the part is the correct OEM-specified replacement.
Key Features
- OEM-Grade Sealing Material — Manufactured to Multiquip's original material and compression specifications for the B46B90 exhaust port, delivering the heat resistance and sealing integrity the application demands.
- Direct Bolt-On Replacement — Matches the original exhaust port flange dimensions of the B46B90 exactly, seating cleanly against mating surfaces without trimming or rework.
- Confirmed B46B90 Fitment — Engineered specifically for the B46B90 walk-behind power trowel; cross-reference part number 797770 against your machine before ordering to confirm compatibility.
- Exhaust Integrity Under Load — A sound exhaust gasket maintains proper back-pressure and prevents hot gas leaks that can damage surrounding components, degrade engine performance, and create unsafe operating conditions.
- Safety-Critical Exhaust Seal — A failed or missing exhaust gasket allows combustion gases to escape near the operator and engine components; replacing with a genuine OEM gasket restores proper containment and safe operation.
An exhaust gasket forms the seal between the engine's exhaust port and the exhaust pipe or manifold, preventing hot combustion gases from escaping at that joint. On a walk-behind power trowel like the B46B90, a compromised exhaust gasket can allow exhaust gases to leak toward the operator, cause audible popping or hissing under load, and expose nearby engine components to heat damage. Replacing a worn or blown gasket promptly keeps the exhaust system operating as designed and protects the engine from the secondary damage a leak can cause over time.
