The JLG 2780282 Reductor Hub is a precision-engineered replacement built to meet OEM fit and performance standards. This component plays a critical role in the drivetrain system by transferring torque from the drive motor to the wheel assembly while reducing rotational speed and increasing output torque.
Designed for heavy-duty construction and industrial environments, this final drive hub assembly ensures reliable power distribution, improved traction, and long-term operational stability in rough terrain conditions.
Key Features:
- OEM-spec design for accurate fitment
- High-strength gear housing construction
- Optimized torque transfer and load distribution
- Built for heavy-duty boom lift applications
- Ideal replacement for worn or damaged reduction hubs
Replacing a worn reductor hub helps prevent drivetrain failure, excessive vibration, and uneven wheel performance.
1. What is the JLG 2780282 reductor hub?
The JLG 2780282 reductor hub is a final drive reduction assembly that transfers torque from the hydraulic drive motor to the wheel. It reduces rotational speed while increasing torque, allowing the boom lift to move efficiently over rough terrain.
2. What are signs that a reduction hub needs replacement?
Common symptoms include:
- Grinding or abnormal drivetrain noise
- Oil leakage from the hub
- Reduced traction or uneven wheel movement
- Excessive vibration while driving
- Metal debris in gear oil
Ignoring these issues can lead to more severe drivetrain damage.
3. Which JLG models use the 2780282 hub assembly?
This reductor hub is typically found on selected JLG rough-terrain boom lifts. Exact compatibility depends on:
- Model
- Serial number
- Drive configuration
Always confirm fitment through your equipment parts manual before ordering.
4. Can a damaged reductor hub affect machine safety?
Yes. A worn or failing reduction hub can:
- Reduce traction
- Cause drivetrain imbalance
- Lead to wheel lock or failure
- Increase risk of breakdown on job sites
Timely replacement ensures operational safety and machine reliability.
