The Multiquip 27930111L1 Muffler Complete is a genuine OEM part designed for the B46S90 walk-behind power trowel. Sourced directly from Multiquip, this muffler delivers the exact fit and exhaust flow characteristics the machine was engineered around. Confirm your model code before ordering to ensure a straight swap with no surprises on the job.
Key Features
- Genuine OEM Exhaust Spec: — Manufactured to Multiquip's original design, matching the correct back-pressure and exhaust flow profile for the B46S90 engine.
- Direct-Mount Replacement: — Bolt pattern, inlet diameter, and mounting orientation match the original, allowing a clean installation against the existing exhaust port and hardware.
- Confirmed B46S90 Fitment: — Verified for the Whiteman walk-behind power trowel B46S90 series, so you can order with confidence.
- Sustained Engine Performance: — A properly functioning muffler maintains correct exhaust scavenging; a cracked or blocked unit causes rough running, overheating, and power loss at the blade.
- Operator Safety Compliance: — Replaces damaged or perforated mufflers that expose operators to excessive exhaust noise and hot gas — a genuine concern on a hand-operated trowel where the operator works in close proximity to the engine.
The muffler on a walk-behind power trowel channels burned exhaust gases away from the engine and reduces noise to an operator-safe level. It also plays a direct role in maintaining proper engine back-pressure, which affects throttle response and overall power output at the finishing blades. When a muffler cracks, corrodes, or becomes blocked, the engine runs poorly, exhaust temperatures rise, and the operator is exposed to elevated noise and fumes — making timely replacement essential for both performance and safety.
