When you’re hearing that telltale whining from your final drive or feeling some slop in the drivetrain during turns, it’s time to address the planetary gears before a minor issue becomes a major headache. This repair kit for ZF APL335 final drives gives you the critical components that typically wear out first—saving you from having to replace the entire final drive assembly down the road.
What You’re Getting
- 18 and 21 tooth planetary gears that restore proper mesh patterns and eliminate noise
- 116.4mm shaft assembly built to handle the heavy torque loads these tractors put out
- Precision-manufactured components that meet ZF specifications for long-term reliability
- All the high-wear parts in one kit so you can tackle the job in one go
Built for Real Farm Work
The ZF APL335 final drives in these Ford New Holland and Case IH tractors see serious stress every time you’re pulling implements, pushing with a loader, or climbing hills. The planetary reduction system is what gives you that pulling power at the wheels, but it also means these gears take a beating. Whether you’re working with utility tractors for general farm duties or larger row-crop machines handling heavy fieldwork, this kit gets you back to smooth, quiet operation.
Made to Last
Farm equipment doesn’t get babied, and these replacement gears are built to handle whatever you throw at them. The precision manufacturing ensures proper clearances and mesh patterns, while the quality steel construction resists the wear that comes from constant heavy loads and field vibration. When planetary gears start wearing, metal particles contaminate the oil and accelerate damage—this kit stops that cycle before it ruins expensive housing components.
Installation Notes
This is a final drive teardown job that requires draining the unit and careful disassembly to reach the planetary carrier. Keep everything absolutely clean during the repair—any debris will quickly damage your new gears. While you’re in there, take a good look at the sun gear, ring gear, and bearings. Use only the specified gear oil and proper fill levels when reassembling.
