When your clutch starts slipping under load or grabbing rough during engagement, it's time to replace that worn-out disc before it leaves you stuck in the field. This 12-inch main drive clutch disc gives you the smooth engagement and reliable power transfer your Massey Ferguson needs to keep working hard. You'll feel the difference right away when shifting becomes smooth again and your tractor pulls with full power. What You're Getting 12-inch diameter delivers the torque capacity you need for demanding farm work Organic friction material provides smooth engagement without grabbing or chattering Steel back construction holds up to the heat and stress of heavy operations 10-spline hub fits your transmission input shaft perfectly without wobble or wear Direct replacement design means no modifications or special tools needed Built for Real Farm Work This disc is engineered for the split torque clutch systems found in many Massey Ferguson tractors across their 100, 200, 300, 500, and 600 series models. These are the workhorses you'll find pulling implements, running loaders, and powering PTO equipment on farms from small acreages to large operations. The 12-inch size handles the power these mid to high-horsepower tractors produce while giving you precise control. Made to Last Farm clutches take a beating from heavy loads, dusty conditions, and stop-and-go field work. The organic friction material on this disc is formulated to handle the heat buildup from clutch slippage while the steel backing plate resists warping and cracking. You'll get reliable service even under demanding conditions like pulling loaded wagons or operating heavy implements. Installation Notes This is a complete transmission-out job that requires splitting the tractor between the engine and transmission. Make sure to use a clutch alignment tool to center the disc properly before tightening down the pressure plate. A quick tip - check your pilot bearing and release bearing while you're in there since they're easy to replace when everything's apart.
