The Multiquip 16450ZDW003 Fuel Injector Assembly is a genuine OEM component designed for the MD105 mid-sized hydraulic ride-on power trowel. Sourced directly through Multiquip's authorized parts network, this assembly delivers the exact fit and calibration required to maintain proper fuel delivery on your MD105. If your trowel is running rough, losing power, or showing signs of poor combustion, replacing the fuel injector assembly with the correct OEM part restores engine performance to spec. DHS Equipment stocks this part to keep your finishing equipment back in service without guesswork.
Key Features
- OEM-Calibrated Fuel Delivery — Built to the exact spray pattern and flow rate specification required by the MD105 engine, ensuring complete combustion and consistent power output.
- Direct-Fit Assembly — Engineered as a complete injector assembly that seats and connects to the MD105 fuel system without adapters or modifications to mounting points or fuel lines.
- MD105 Trowel Compatibility — Confirmed fitment for the Multiquip MD105 hydraulic ride-on power trowel series; always verify your model before ordering.
- Combustion Efficiency Restored — A worn or clogged injector causes rough idling, misfires, and loss of blade-control power; this assembly brings fuel atomization back to operating specification.
- Fuel System Integrity — Proper injector sealing and calibration are critical in fuel systems — using the correct OEM assembly prevents fuel leaks and unmetered fuel delivery that can damage the engine over time.
A fuel injector assembly controls the precise delivery of atomized fuel into the engine's combustion chamber, metering the correct quantity and spray pattern at the right moment in the engine cycle. On a hydraulic ride-on trowel like the MD105, consistent engine power directly drives the hydraulic system that controls blade pitch and machine propulsion — so any degradation in fuel delivery translates immediately into reduced troweling performance and uneven finishing results. When the injector wears, clogs, or fails to seal correctly, symptoms include hard starting, rough running, excessive smoke, and loss of hydraulic response, making timely replacement essential to keeping the machine productive.
