Description
When your front axle starts making that grinding noise during turns or your four-wheel drive just doesn’t feel right anymore, it’s usually the crown wheel and pinion calling for attention. This critical gear set transfers power from your differential to the front wheels, and when it wears out, you lose the reliable traction that keeps you productive in muddy fields and steep ground. This replacement set gets your front end back to working like it should.
What You’re Getting
- Precision-machined gear teeth that mesh perfectly for smooth power transfer
- Heat-treated construction that handles the high torque loads of heavy implements
- Exact tooth count configuration engineered for proper gear reduction
- Direct replacement design that fits your existing differential housing
- Complete set includes both crown wheel and pinion for total rebuild
Built for Real Farm Work
This gear set is designed for the workhorse John Deere 40, 50, 51, and 55 series tractors that handle everything from loader work to heavy tillage. Whether you’re running a 2140 on smaller acreage or pushing a 2850 through tough conditions, these tractors depend on reliable front-wheel assist to maintain traction when the going gets rough.
Made to Last
The gears are precision-ground to exact tolerances and heat-treated for maximum durability. This isn’t just any gear set – it’s engineered to handle the constant shock loads and high torque demands of agricultural work. The proper hardness and surface finish ensure these gears will mesh smoothly and resist wear for years of reliable service.
Installation Notes
This is a complete differential teardown job that requires proper setup tools and experience. You’ll need to establish correct gear mesh pattern using marking compound and adjust backlash to manufacturer specs. Replace your front axle seals while you’ve got it apart, and don’t forget to refill with fresh gear oil when you’re done.
