Description
When your front axle starts making that grinding or whining noise during turns, or you notice clunking sounds under load, you know exactly what’s happening—those planetary gears inside your ZF APL345 final drive are telling you they’ve had enough. Ignoring those warning signs only makes the repair more expensive, and nobody wants to be stuck in the field with a broken front axle when there’s work to be done.
What You’re Getting
- Complete planetary gear set with precision 18 and 22 tooth gears engineered for your ZF APL345 unit
- 119mm shaft assembly built to handle the heavy torque loads from four-wheel drive operation
- All essential wear components in one kit—no hunting around for individual parts that might not match
- Direct replacement that restores original performance without modifications
Built for Real Farm Work
These APL345 final drives are found on Ford 10 Series and TW Series tractors built for heavy tillage and large-scale operations, Case IH 43-95 Series tractors handling everything from row crops to livestock work, and John Deere 40, 50, and 55 Series models tackling diverse agricultural tasks from grain farming to hay production. Whether you’re pulling heavy implements, working slopes, or pushing through muddy conditions, these planetary gears multiply the torque going to your front wheels.
Made to Last
Your front axle planetary gears take tremendous abuse every time you engage four-wheel drive, especially when you’re pulling through tough spots or working with a loader. This kit uses heavy-duty materials designed to handle the shock loads and constant stress that would destroy lighter components. The precision-cut gears ensure proper mesh patterns and reduce heat buildup that accelerates wear.
Good to Know
Plan on a full day for this rebuild—it’s not complicated, but you want to do it right the first time. You’ll need to drain the final drive oil and remove the wheel hub to access the planetary unit. Mark all components before disassembly with a paint pen, clean everything thoroughly, and use fresh gear oil when you reassemble. Those planetary carriers can go back together several ways, but only one is correct.
