Description
When you’re out in the field and your transmission isn’t shifting smoothly between gears, you know it’s time to look at the internals. This constant mesh transmission gear with 42 teeth plays a crucial role in delivering power from your engine to the ground, especially in those 8-speed setups that give you precise control for every farm task.
Key Features
- 42-tooth constant mesh design provides smooth power transfer without grinding or binding
- Built specifically for 8-speed transmissions in your 590 and similar Massey models
- Heavy-duty construction handles the torque from these mid-range utility tractors
- Machined to exact tolerances for proper meshing with other transmission components
Built for Real Farm Work
This gear fits right into the heart of Massey Ferguson’s reliable transmission systems found in utility tractors like the 565, 575, and 590 from the 500 series, along with the 675 from the 600 series and various models from the 4200 and 4300 series. These tractors are the workhorses that handle everything from hay production to loader work around the farm.
Made to Last
Constant mesh gears take a beating, especially when you’re shifting under load or dealing with heavy implements. This gear is manufactured from quality steel and heat-treated to handle the stresses of daily farm operation. The precise tooth profile ensures smooth engagement and helps prevent the premature wear that can sideline your tractor during busy seasons.
Good to Know
Replacing transmission gears requires splitting the tractor, so this isn’t a quick field repair. If you’re hearing grinding noises or experiencing hard shifting, have the entire transmission inspected while it’s apart. Always use the proper transmission fluid and check fluid levels regularly to keep these gears running smooth for years to come.
