Built for Real Farm Work
Whether you’re running a 390 through harvest dust, using heavy tillage equipment, or operating in conditions where dust hangs in the air, this tractor sees plenty of demanding work. The one ram axle design in these 300 series tractors is known for durability, but seals and bearings eventually wear from the constant loads of field work, loader operations, and transport duties.
Made to Last
Farm equipment bearings take a beating—constant rotation under heavy loads, dirt, moisture, and temperature swings that would destroy ordinary bearings. This replacement uses the same exacting specifications as the original, with precision grinding for smooth operation and materials that stand up to the punishment.
Good to Know
This is a job that requires proper tools—use bearing pullers and installers to avoid damage during installation. Clean the housing thoroughly and inspect for wear while you’re in there. A good tip from experienced mechanics: if you’re hearing final drive noise, don’t wait—prompt replacement prevents the kind of expensive damage that can sideline your tractor during busy season.
