The Multiquip 84006668 Speed Sensor MD80 is a genuine OEM component designed for the MD80 hydraulic ride-on power trowel. Sourced directly from Multiquip, this sensor meets the original design specifications for the MD80 series, ensuring accurate signal output and correct integration with the machine's hydraulic control system. If your MD80 is exhibiting erratic blade speed, inconsistent drive response, or control system faults, replacing the speed sensor is a critical first diagnostic step.
Key Features
- Genuine OEM Signal Accuracy — Built to the exact output specification required by the MD80 hydraulic control system, ensuring the trowel's electronics receive a clean, accurate speed signal.
- Direct-Fit for MD80 — Engineered specifically for the MD80 mid-sized hydrostatic ride-on trowel; installs into the original sensor mounting location without alteration.
- MD80 Series Compatibility — Confirmed fitment for MD80 hydraulic ride-on power trowels; use your model code to verify before ordering.
- Protects Hydraulic Drive Performance — A functioning speed sensor keeps blade rotation and drive control operating in sync; a failed sensor can cause unpredictable machine behavior and loss of finishing consistency.
- Electrical System Integrity — As a genuine OEM electrical component, this sensor carries the correct connector type and resistance profile, preventing control board errors caused by signal mismatch.
The speed sensor on the MD80 ride-on trowel monitors rotational speed and feeds that data to the machine's hydraulic control system, allowing it to regulate blade pitch and drive response accurately. When the sensor degrades or fails, the trowel may display erratic speed readings, trigger fault codes, or lose the smooth, controlled blade action needed for quality concrete finishing. Replacing a worn sensor with a genuine OEM part restores accurate feedback to the control system and keeps the machine performing as designed.
