Description

When your tractor starts making grinding noises 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 handle all the power from your engine to the wheels, and they’re what give you the torque multiplication needed for heavy pulling and tough field conditions. This replacement set gets your drivetrain running smooth again.

What You’re Getting

Precision-cut gear teeth that mesh properly and reduce noise and vibration
Heat-treated construction that handles the high torque loads your John Deere dishes out
Exact tooth count configuration engineered for your specific differential
Complete set so both gears wear together properly from day one

Built for Real Farm Work

This crown wheel and pinion set is designed for John Deere tractors with APL345 differentials across the 40 and 50 series lineup. Whether you’re running a mid-size utility tractor for hay work or a bigger machine for row crop farming, these are the same gears that transfer your engine’s power to the wheels for all that pulling, pushing, and hill climbing.

Made to Last

Farm equipment gears take a pounding, especially when you’re pulling heavy loads or working in tough conditions. This set uses the same metallurgy and heat treatment as the original equipment, so the gear teeth stay hard where they need to be while the gear body remains tough enough to handle shock loads without cracking.

Installation Notes

This is a precision job that requires proper setup of gear mesh patterns and bearing preloads. Most experienced mechanics plan on a full day for the job, and you’ll need clean gear oil for reassembly. Always replace both gears as a set – mixing new and worn gears leads to rapid failure.
