The Multiquip 16400ZDW003 Throttle Body Assembly MD105 is a genuine OEM component designed for the MD105 mid-sized hydrostatic ride-on power trowel. Sourced directly from Multiquip, this part meets the exact specifications required for proper throttle control and engine response on MD105 machines. If your trowel is experiencing erratic idle, poor throttle response, or fuel delivery issues, replacing the throttle body assembly with the correct OEM unit restores proper operation quickly and confidently.
Key Features
- Genuine OEM Throttle Calibration — Manufactured to Multiquip's exact fuel and airflow specifications, ensuring the throttle body meters the air-fuel mixture the way the MD105 engine was designed to receive it.
- Direct-Fit for MD105 Trowels — Engineered specifically for the MD105 hydrostatic ride-on trowel, with matching port dimensions and mounting points that align with the original installation.
- Restores Smooth Engine Response — A worn or damaged throttle body causes rough idling, sluggish acceleration, and inconsistent blade speed; this assembly brings engine response back to specification.
- Complete Assembly — Supplied as a full throttle body assembly, minimizing the number of individual components needed and simplifying the repair process.
- Fuel System Integrity — As a genuine OEM fuel system component, this assembly helps maintain correct fuel delivery and combustion efficiency, which is critical for consistent trowel performance across a full concrete finishing cycle.
The throttle body assembly controls the flow of air into the engine by regulating a valve that opens and closes in response to operator throttle input. On a hydrostatic ride-on trowel like the MD105, consistent engine speed directly affects hydraulic pressure and blade pitch control — so a malfunctioning throttle body can lead to uneven finishing, loss of drive response, or difficulty maintaining working RPM. When the assembly degrades or fails, replacing it with the correct OEM unit — such as the Multiquip 16400ZDW003 — ensures the engine receives the right air-fuel ratio at all throttle positions, restoring full machine control.
