Your John Deere’s differential is what lets you steer around corners and keeps power flowing to both wheels even when one’s spinning. When that clutch pack starts slipping or the steel discs get grooved up, you’ll know it—the tractor won’t turn like it should, or you might notice odd grinding noises when cornering. This steel disc is one of those critical parts that keeps your rear end working the way it should.
What You’re Getting
- Precision-machined 12-tooth steel disc that transfers power properly between differential components
- Proper 252mm outside diameter for exact fit in your differential housing
- Heat-treated steel construction that stands up to the tremendous forces in your rear end
- Works with the friction disc (part 580423) to provide smooth, controlled engagement
Built for Real Farm Work
This disc fits the rear axle differentials on a wide range of John Deere tractors, from the classic 20 and 30 series machines up through the modern 6R and 7R series. Whether you’re running an older 4230 for chores or a big 9470R pulling heavy implements across wide fields, this is the same quality steel disc that keeps your tractor steering smoothly.
Made to Last
Differential work is tough—high torque, constant engagement and disengagement, and occasional shock loads when you hit rough ground. This steel disc is engineered to handle all of it. The machined teeth mesh precisely with the mating components, and the steel is treated to resist wear even under heavy use.
Good to Know
Differential work isn’t a quick weekend job—you’ll need hydraulic jacks, pullers, and some serious mechanical experience. Make sure to replace both the steel disc and its mating friction disc at the same time for best results. If you’re in there anyway, it’s worth checking the condition of the spider gears and side gears while everything’s apart.
