Planetary Gear for ZF APL345 Front Axle Systems – 34 Teeth

Description

When your front axle starts making grinding noises or your 4WD isn’t engaging like it used to, you might be looking at worn planetary gears. This 34-tooth planetary gear is designed for ZF APL345 front axles found on numerous high-performance agricultural tractors including Ford 10 Series and TW Series tractors used for heavy tillage and harvesting, Case IH 43-95 Series tractors for row-crop farming, and John Deere 40-55 Series models handling diverse agricultural tasks. It’s the internal gear that helps transfer power from your differential to the wheels while reducing speed and multiplying torque.

What You’re Getting

• Precision-machined 34 teeth for exact engagement with other planetary components
• Proper internal diameter (56.3mm) and outside diameter (77mm) for perfect fit in APL345 housings
• 36mm width provides the bearing surface needed to handle heavy torque loads
• Heat-treated construction that stands up to the stress of field work and loader operations

Built for Real Farm Work

These MFWD systems provide enhanced traction and improved steering control essential for operating heavy implements, working on slopes, and maintaining productivity in challenging field conditions such as wet soil or loose terrain. Whether you’re running a Ford TW series handling heavy tillage, a John Deere 3640 on hay duty, or a Case IH 956 working livestock, these tractors ranging from 75-150 HP are the workhorses on many farms.

Made to Last

Planetary gears take tremendous stress as they multiply torque while reducing wheel speed. This gear is manufactured to handle the constant loading and unloading cycles that come with farm work, from pulling heavy implements through tough soil to managing loader duties around the farmyard.

Good to Know

Replacing individual planetary components rarely succeeds – worn parts damage new ones quickly. A complete rebuild restores original tolerances and ensures all components work together properly for maximum service life. If you’re replacing this gear, it’s worth inspecting the other planetary components, bearings, and seals while you’ve got the axle apart.
