The Multiquip 48632 Muffler MD105 is a genuine OEM muffler designed for the MD105 mid-sized hydrostatic ride-on power trowel. Sourced directly from Multiquip, this part is an exact match for the original component, ensuring proper exhaust routing, sound attenuation, and a bolt-on installation without guesswork. If your MD105 is running louder than normal or showing signs of exhaust leakage, this is the correct OEM replacement to restore it to spec. DHS Equipment stocks this part so you can get your trowel back on the slab fast.
Key Features
- Genuine OEM Exhaust Specification — Manufactured to Multiquip's original design, matching the exact exhaust outlet diameter, baffle configuration, and heat tolerances required by the MD105 engine system.
- Direct-Mount Compatibility — Engineered specifically for the MD105 hydrostatic ride-on trowel; mounts to the factory exhaust port with original hardware and no bracket modifications.
- MD105 Series Fitment — Confirmed fitment for the Multiquip MD105 mid-sized hydrostatic ride-on power trowel.
- Restored Engine Back-Pressure Balance — A properly functioning muffler maintains the correct exhaust back-pressure for the engine; a cracked or failed muffler can affect power output and accelerate engine wear.
- Exhaust Integrity and Operator Safety — A sealed, intact muffler keeps exhaust gases directed away from the operator and prevents carbon monoxide from accumulating at ground level on enclosed or semi-enclosed pour sites.
The muffler on a ride-on trowel serves two critical roles: it reduces combustion noise to manageable levels and directs hot exhaust gases safely away from the engine bay and operator. Inside the muffler, exhaust pulses pass through a series of chambers and baffles that dissipate pressure and absorb sound before gases exit. When a muffler cracks, corrodes, or develops a failed gasket joint, the result is increased exhaust noise, potential exhaust leakage near the operator platform, and in some cases a disruption to the engine's tuned back-pressure that can reduce power and fuel efficiency. Replacing a damaged muffler promptly keeps the MD105 running cleanly and the work environment safe.
