Key Features
- Genuine OEM Quality — Manufactured to original Genie specifications, ensuring dimensional accuracy and correct calibration for the Z482 T4 engine application.
- Direct OEM Replacement — Engineered to install in place of the original injector with no adaptation, maintaining the correct fuel delivery characteristics for the engine.
- Broad Model Coverage — Fits Z-34/22 N, Z-34/22 DC, Z-34/22 Bi-Energy, Z-45/25, Z-45/25J DC, and Z-45/25J Bi-Energy articulating boom lifts.
- Engine Performance — A correctly functioning injector delivers the proper metered fuel charge to each cylinder, supporting consistent power output and smooth engine operation. A worn or failing injector can cause misfires, rough running, and loss of machine performance.
- Operational Safety — On an articulating boom lift, consistent engine performance is directly tied to safe, controlled operation at height. Replacing a failed injector with a genuine OEM part restores the reliable power delivery the machine depends on.
An injector meters and atomizes fuel into the engine's combustion chamber at precisely timed intervals, making it one of the most performance-critical components in the engine. On the Kubota Z482 T4 engine used in these Genie articulating boom lifts, each injector must deliver a consistent, finely atomized spray to ensure clean combustion and steady power output. When an injector becomes worn, clogged, or fails, the result is uneven combustion — leading to rough idling, reduced power, increased fuel consumption, and in severe cases, engine shutdown. Replacing the injector promptly with the correct OEM part restores proper engine function and keeps the machine operating as intended.
