Description
When you’re dealing with transmission problems on your Ford 40 series or TS series tractor, worn or damaged gears are often the culprit behind grinding, slipping, or complete power loss. This replacement transmission gear gets your tractor back to delivering reliable power transfer through the drivetrain, whether you’re pulling a heavy implement through tough ground or pushing snow with a loader.
What You’re Getting
- Precision-manufactured gear with 48 and 42 teeth configuration for exact replacement
- Dumb bell design that fits the SLE transmission system properly
- Heat-treated construction that handles the stress of heavy pulling and PTO work
- Direct replacement part that restores original transmission performance
Built for Real Farm Work
This gear is engineered for Ford New Holland 40 series tractors (5640, 6640, 7740, 7840, 8240, 8340) and TS series models (TS90, TS100, TS110, TS115). These are proven workhorses that handle everything from field cultivation and hay production to loader work and heavy tillage operations where reliable power transmission is critical.
Made to Last
Farm transmissions take serious punishment, and this gear is built to handle it. The precision tooth profile and proper heat treatment ensure it meshes smoothly with other transmission components while standing up to the torque loads these tractors produce during heavy pulling and PTO operation.
Installation Notes
This is a major transmission repair that requires complete disassembly of the gearbox. Professional installation is strongly recommended due to the complexity of timing and proper assembly procedures. Always use fresh transmission fluid and inspect related gears and synchronizers while you have everything apart.
