Description
If you’ve been hearing grinding or whining noises coming from your transmission area, especially when shifting through the ranges, this front bearing is likely what’s calling for attention. When your range box starts making grinding noises or won’t engage properly, don’t let a worn gear leave you stuck in one range or worse, stranded in the field with no drive. The range box front bearing supports critical rotating components inside your transmission, handling the constant loads and vibration that come with real farm work.
Key Features
- Precision-manufactured for exact fit in your range box housing
- High-grade steel construction designed to handle the heavy loads of agricultural use
- Proper lubrication channels and sealing to protect against contamination
- Direct replacement for worn original bearings – no modifications needed
Built for Real Farm Work
These Massey Ferguson tractors revolutionized farm efficiency with their innovative speedshift transmissions. The 300 series (365-399) and 4200/4300 series (75-99 hp) are beloved by farmers for their versatility in handling everything from cultivation and planting to hay production and loader work. Whether you’re running your 375 through heavy tillage or using your 4240 for loader duties around the barn, this bearing ensures smooth power transfer through the range box that gives you all those speed options.
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. Quality heat treatment and manufacturing tolerances ensure this bearing will provide reliable service through seasons of demanding work.
Good to Know
Range box work requires splitting the tractor or significant disassembly, so most operators tackle this during other major service. 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. It’s smart to check the condition of other range box components while you have access – worn gears or shafts can quickly destroy a new bearing.
