The Genie 227776GT is a genuine OEM Wheel Drive with Brake, 86.74:1, built for Genie S-series telescopic boom lifts and Z-series articulating boom lifts including the S-80X, S-80, S-85, and Z-80/60. Sourced directly from Genie, this component meets the exact engineering standards of the original part installed at the factory. Cross-reference part number 227776GT against your machine's parts manual to confirm fitment before ordering. If you're servicing a high-reach S or Z boom that's lost drive power or showing brake irregularities, this is the assembly that restores full function.
Key Features
- OEM-Matched Gear Ratio — Engineered to the precise 86.74:1 reduction ratio, ensuring drive torque and travel speed match the original performance envelope of your boom lift.
- Integrated Brake Assembly — Combines the drive motor and brake into a single bolt-on unit, streamlining installation and eliminating the need to source or match separate brake components.
- Direct OEM Replacement — Designed as a drop-in fit for the S-80X, S-80, S-85, and Z-80/60, using the same mounting interface and connection points as the original unit.
- Restores Full Drive Capability — A worn or failed wheel drive assembly can result in loss of machine propulsion or inconsistent braking — this part returns the unit to full, dependable operation.
- Safety-Critical Function — On large telescopic and articulating boom lifts, the integrated brake holds the machine stationary on grades and during platform use; a correctly functioning unit is essential to safe operation at height.
The wheel drive assembly on a self-propelled boom lift combines a gearbox reduction unit with an integrated parking and service brake, transmitting motor power to the drive wheel at a controlled torque and speed. The 86.74:1 gear ratio steps down motor output to deliver the pulling force these large booms need to maneuver across job sites, while the built-in brake holds the machine securely when the drive is disengaged. When this assembly begins to fail — through gear wear, seal leaks, or brake degradation — operators may notice sluggish or uneven propulsion, difficulty holding position on a slope, or complete loss of drive on one corner of the machine.
