Description
When your tractor starts making grinding noises from the rear end or you feel that telltale vibration through the seat, it’s often the crown wheel and pinion in your differential that’s calling for help. These gears are the heart of your drivetrain—they take all the power from your engine and transfer it to the wheels with the proper gear reduction needed for pulling heavy loads and working in tough field conditions.
What You’re Getting
- Complete crown wheel and pinion set engineered for the Z9/31 differential configuration in your MF tractor
- Precise gear tooth geometry that meshes smoothly and distributes power evenly to both rear wheels
- Heat-treated steel construction built to handle the shock loads from implements and heavy pulling
- Direct replacement set that fits without modifications—same specifications as your original equipment
Built for Real Farm Work
This crown wheel and pinion set is designed specifically for Massey Ferguson 365, 375, and 390 tractors—the workhorse models that handle everything from cultivation and planting to hay operations and loader work. Whether you’re pulling a heavy disc through tough ground or running a big round baler, these are the gears that multiply your engine’s torque and get that power to the wheels where you need it.
Made to Last
Differential gears take tremendous punishment, especially when you’re working in challenging conditions or pulling heavy implements. This set is manufactured to OEM specifications with proper heat treatment and precise machining to ensure smooth operation and long service life, even under the demanding conditions of daily farm work.
Good to Know
Replacing a crown wheel and pinion requires splitting the rear end and setting proper gear backlash—it’s definitely a job for someone experienced with differential work or best handled by a qualified shop. When installing, proper gear oil and torque specifications are critical for long-term reliability.
