Description
When you’re dealing with MFWD issues—maybe you’re hearing grinding noises during turns or feeling the front wheels binding up—there’s a good chance you need to look at the differential discs. These fiber discs work in the front differential’s limited slip system to control power transfer between the front wheels, ensuring smooth operation when turning and preventing tire scuffing on pavement.
What You’re Getting
- Precision-cut fiber disc with 25 teeth for smooth engagement and power transfer
- High-strength fiber material that handles the heat and pressure of differential operation
- Exact 1mm thickness maintains proper clutch pack spacing for optimal function
- Direct replacement for worn discs that are causing binding or uneven wear
Built for Real Farm Work
This disc fits a wide range of John Deere tractors with MFWD, from the reliable 4000 series utility tractors up through the heavy-duty 8R series row-crop machines. Whether you’re running a 6000 series doing loader work, a 7000 series pulling cultivation equipment, or an 8000 series handling your biggest implements, this is the same quality disc John Deere uses in their differentials.
Made to Last
The fiber construction resists glazing and maintains its grip characteristics even under the high loads and temperatures that MFWD systems generate. Unlike steel discs that can score and damage mating surfaces, these fiber discs provide consistent friction while protecting expensive differential components.
Good to Know
Differential work requires removing the front axle and splitting the differential case, so it’s a job for someone comfortable with precision assembly work. Always replace discs as complete sets to ensure even engagement, and check the steel discs (part 580422) for scoring while you’re in there. A thin film of the specified differential oil on each disc during assembly helps prevent initial sticking.
