Description

When your tractor starts making grinding noises from the back end or you notice uneven tire wear, it’s often a sign that your differential’s crown wheel and pinion are wearing out. This 11/45 tooth ratio crown wheel and pinion set with hydro lock transfers power from your transmission to the rear wheels and controls how your tractor handles turns and traction. Without a properly functioning differential, you’ll struggle with tire wear and handling issues that make field work more difficult.

What You’re Getting

Precision-machined 11/45 tooth ratio designed for optimal power transfer and gear reduction
Heat-treated steel construction that stands up to the constant stress of heavy loads and field conditions
Hydro lock feature that prevents wheel slip during demanding applications like pulling implements through tough soil
Complete crown wheel and pinion set – everything you need to restore proper differential operation

Built for Real Farm Work

This differential set fits the workhorse Massey Ferguson 3000 and 3100 series tractors that are the backbone of many farming operations. These mid-range tractors handle everything from hay operations and livestock feeding to row crop work and loader duties. Whether you’re running a 3070 utility tractor around the farmstead or putting a 3120 through its paces during planting season, this differential set keeps power flowing smoothly to both rear wheels.

Made to Last

Farm differentials take tremendous abuse from heavy implements, uneven terrain, and constant direction changes. This crown wheel and pinion set uses properly heat-treated steel that resists wear and maintains precise gear mesh patterns even after years of service. The machining tolerances ensure smooth, quiet operation that won’t leave you listening for grinding sounds every time you make a turn.

Installation Notes

This is a complete differential rebuild job that requires removing the rear axle housing and properly setting gear mesh patterns with a dial indicator. You’ll need to check backlash and bearing preload according to Massey Ferguson specifications. Replace the axle housing seals during installation and use fresh differential fluid to protect your investment. If you haven’t done differential work before, this is definitely a job for an experienced mechanic.
