Description
When your tractor starts shaking under load or you feel vibrations coming through the seat during heavy pulling, a worn drive shaft torsion damper is often the culprit. This little component sits between your clutch and transmission, smoothing out the power pulses and torsional vibrations that big diesel engines naturally produce. When it starts failing, you’ll feel it – especially during heavy pulling or PTO work.
What You’re Getting
- Torsion spring design that absorbs engine power pulses and drivetrain vibrations
- Direct replacement for underdrive-equipped 5620, 5720, and 5820 models
- The torsion springs maintain their tension through thousands of cycles, keeping vibrations dampened season after season
- Precise fit that restores smooth power transfer from engine to transmission
Built for Real Farm Work
This damper is designed for John Deere 5620, 5720, and 5820 tractors equipped with underdrive transmissions. These are the workhorses handling everything from loader work around the farmyard to field operations like planting, cultivating, and harvesting. Whether you’re running your 5720 through long days of hay work or using your 5820 for heavy transport duties, this damper keeps power flowing smoothly when you need it most.
Made to Last
Farm equipment takes a beating, and clutch dampers see constant stress from engine torque pulses and transmission loads. This one’s built with quality materials and proper heat treatment to handle the demanding conditions these big tractors face. The internal springs resist fatigue even under the constant cycling of diesel power delivery.
Installation Notes
Installation requires splitting the tractor between engine and transmission – this is major repair work that’s usually done during off-season overhauls or when other clutch components need attention. If you’re experiencing clutch problems, it’s smart to replace the damper while everything’s apart rather than risk having to split the tractor again later.
