If you've ever been stuck in the field with a tractor that won't crank, you know how frustrating it can be when your starter just grinds and spins without catching. Most of the time, it's not the starter that's failed—it's the flywheel ring gear that's worn down. This 122-tooth ring gear is what your starter engages to turn the engine over, and when those teeth get chipped or worn, you're not going anywhere. What You're Getting 122-tooth ring gear engineered to exact OEM specifications for reliable engagement Heat-treated steel construction that stands up to the repeated stress of starting Precisely machined teeth that mesh smoothly with your starter drive gear Direct replacement that fits like the original—no modifications needed Quality materials that resist chipping and wear from daily use Built for Real Farm Work This ring gear fits a wide range of Massey Ferguson tractors, from the utility-sized 298 up through the bigger 1000 series machines. Whether you're running a compact tractor for livestock chores or operating a larger machine for row crop work, reliable starting is essential when there's work to be done. These tractors handle everything from hay operations to heavy tillage, and they need to fire up every time you turn the key. Made to Last The ring gear takes a beating every time you start your tractor—the starter drive slams into those teeth with considerable force. This replacement is built with the same heat treatment and tooth geometry as the original, so it'll handle thousands of starts without premature wear. Quality steel construction means you won't be doing this job again anytime soon. Installation Notes Ring gear replacement requires removing the flywheel, so this is typically a job for someone comfortable with major engine work or a good shop. The old gear usually needs to be heated to expand it for removal, and the new one should be heated before installation for proper fit. While you've got everything apart, it's smart to inspect your starter drive gear and replace it if the teeth show wear—a worn starter drive will quickly damage a new ring gear.
