If you've noticed wet spots under your tractor or heard a whining noise from the transmission, there's a good chance one of the seals in your Multi-Power transmission is calling it quits. This seal is designed for the PTO pinion shaft retainer in Massey Ferguson's Multi-Power transmission system, and when it fails, you'll lose hydraulic fluid and potentially damage expensive transmission components. Getting the right seal installed means keeping your power flow smooth and your transmission running like it should. What You're Getting Precision-molded seal with 1.58" ID and 1.945" OD dimensions that matches factory specifications exactly Heavy-duty construction built to handle the pressures and temperatures inside your Multi-Power transmission Direct replacement design that installs without modifications or special tools Red seal material specifically engineered for transmission fluid compatibility Quality that keeps transmission fluid where it belongs—inside the case, not on your shop floor Built for Real Farm Work This seal fits a wide range of Massey Ferguson tractors that came equipped with the Multi-Power 12-speed transmission system. From the smaller 100 series utility tractors up through the powerful 600 series row-crop machines, these tractors have been the backbone of countless farming operations for decades. Whether you're running a 135 for hay work, a 265 for crop farming, or a 390 for heavy field preparation, the Multi-Power transmission gives you the gear range flexibility that makes these tractors so versatile. Made to Last Transmission seals take a beating from constant pressure, temperature changes, and the demanding nature of farm work. This seal is manufactured from materials specifically chosen to resist transmission fluid degradation while maintaining the flexibility needed to create a reliable seal. The WRG125 specification ensures you're getting a seal that meets the original engineering requirements for your Multi-Power transmission. Installation Notes This is a straightforward replacement that any competent mechanic can handle. Clean the seal bore thoroughly before installation, and take your time to get the new seal seated squarely—a cocked seal won't do its job. Keep some fresh transmission fluid handy to top off the system after you're done, and check for leaks after a few hours of operation.
