Description

When you start hearing that tell-tale whining or grinding from the rear differential, or notice your tractor losing power somewhere between the engine and the wheels, it’s often the crown wheel and pinion that’s calling for attention. This critical gear set is what transfers power from your driveshaft to the rear axles—when it wears out, you’ll know it. The good news is this replacement set gets your drivetrain running smooth and strong again.

What You’re Getting

Matched crown wheel and pinion gears engineered to work together perfectly
Precision-cut gear teeth that mesh properly and reduce noise and vibration
Heat-treated construction that handles the torque your Fiat 90 series puts out
Direct replacement design that fits your existing differential housing
Quality components that restore proper gear reduction and power transfer

Built for Real Farm Work

This crown wheel and pinion set is designed specifically for Fiat 90 series tractors—machines that were built for serious agricultural work. Whether you’re running a 115-90 DT on hay ground, pulling heavy implements with a 180-90, or working tight spots with a 160-90, these gears handle the varying loads and demanding conditions that come with farm life.

Made to Last

The differential is one of the hardest-working parts on your tractor, dealing with constant stress from turning, varying wheel speeds, and heavy implement loads. This crown wheel and pinion set is manufactured to handle those demands, with proper heat treatment and precise machining that ensures the gear teeth wear evenly and maintain their mesh pattern over thousands of hours.

Installation Notes

This is definitely a job for someone comfortable with differential work—you’ll need to pull the rear end apart, set proper gear mesh and backlash, and torque everything to specification. It’s also a perfect time to replace seals and check bearings while you’ve got it opened up. Make sure to use the right differential oil when you button it back together.
