Key Features
- Genuine OEM Part — Manufactured to original Genie specification, delivering the dimensional accuracy and material grade required for the Z482 T4 engine application.
- Direct OEM Replacement — Installs in place of the original ring gear with no adaptation needed, restoring the engine's starting system to its original configuration.
- Broad Z-Series Fitment — Fits the 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 Starting Integrity — A correctly functioning ring gear allows the starter to engage cleanly and turn the engine over reliably. A worn or damaged ring gear causes difficulty starting and can accelerate wear on the starter drive.
- Operational Safety — On aerial work platforms, dependable engine starting is essential for safe, controlled operation. Using the correct OEM part helps maintain the integrity of the power system the machine relies on.
The ring gear is mounted on the engine flywheel and provides the toothed interface that the starter motor's drive pinion engages to crank the engine. Each time the engine is started, the starter pinion meshes with the ring gear teeth to rotate the engine through its firing cycle. Over time, the teeth on the ring gear can wear, chip, or crack — particularly under repeated or hard-starting conditions — leading to rough engagement, difficulty starting, or failure to start at all. Replacing a worn ring gear with the correct OEM part restores clean starter engagement and keeps the engine starting system operating as intended.
