Description

That whining noise coming from your final drive isn’t going to magically disappear, and waiting until it completely gives up means you’ll be looking at a whole new axle assembly. When planetary gears start wearing in your ZF APL735 final drive, they create metal shavings that contaminate the oil and damage other expensive components. This repair kit gives you the worn-out parts before they take everything else with them.

What You’re Getting

Complete 121mm planetary shaft assembly with precision 14-tooth and 21-tooth gears
Heavy-duty construction built to handle the continuous high-torque loads farm work demands
Direct replacement components that restore proper gear mesh and eliminate slop
Quality materials that stand up to the shock loads of loader work and field operations

Built for Real Farm Work

These ZF APL735 final drives are found on tractors that see serious use – pulling heavy implements through tough ground, running loaders day in and day out, and climbing hills with loaded spreaders. The planetary reduction system is what gives you that pulling power at the wheels, but it also means these gears take tremendous punishment every time you’re working.

Made to Last

The precision-manufactured gears in this kit restore proper clearances and mesh patterns, bringing back that smooth, quiet operation you remember. These aren’t cheap knock-offs – they’re built to handle everything from spring fieldwork to daily feeding chores, season after season.

Installation Notes

This job requires draining the final drive and careful disassembly to reach the planetary carrier. Absolute cleanliness is critical – even tiny bits of debris will quickly destroy new gears. While you’re in there, inspect the sun gear, ring gear, and all bearings. Use only the specified gear oil and proper fill levels when you button everything back up.
