When your engine's knocking, losing oil pressure, or showing signs of worn main bearings, the heart of the problem is often the crankshaft. This forged replacement crankshaft is built to handle everything from daily chores to season-long harvest marathons. Whether you're rebuilding your trusty old tractor or just trying to get a few more years out of it, a quality crankshaft makes all the difference between a reliable machine and one that leaves you stranded. Key Features Forged steel construction that's stronger than cast iron and handles heavy loads without flexing Includes precision lip seal design that keeps oil where it belongs and dirt out of your engine Single-bolt nose configuration makes pulley and timing gear installation straightforward Compatible with both naturally aspirated and turbocharged Perkins engines Pre-balanced from the factory so you don't need expensive machine shop work Built for Real Farm Work This crankshaft fits a wide range of Massey Ferguson tractors from the smaller 100 series utility machines up through the heavy-duty 600 and 4200 series row-crop tractors. These tractors handle diverse farming operations from field cultivation and hay production to livestock management , and they're powered by proven Perkins 4.236 and 4.248 four-cylinder engines that are known for their durability and fuel efficiency. Made to Last Forged steel construction means this crankshaft can take the abuse that comes with heavy tillage, loader work, and long hours under load. The precision machining ensures proper bearing clearances and oil flow, while the integrated lip seal setup provides better sealing than older rope seal designs. These engines power tractors in demanding applications including heavy tillage, harvesting support, loader work, and continuous PTO operations where reliability is critical . Good to Know This is a complete rebuild job that requires pulling the engine and splitting the case. You'll want to check your main bearing clearances and have the block align-bored if needed. The lip seal requires its own carrier assembly, and don't forget to order new main bearings while you're at it. Most folks find it's worth doing the full rebuild while everything's apart.
When your tractor's engine starts knocking or you're dealing with worn main bearings, there's no getting around it—you need a reliable crankshaft. This isn't a repair you can put off. These Massey Ferguson tractors powered by Perkins engines are workhorses found on farms running everything from grain operations to cattle ranches. Whether you're running a disk, planting corn, cutting silage, or pulling heavy implements , a solid crankshaft keeps your engine running smooth and your operation moving forward. What You're Getting Forged construction that handles the stress and vibration of heavy farm work Precision-balanced assembly for smooth operation and reduced engine wear Single-bolt nose design matches original specifications exactly Complete assembly ready to install—no need to hunt down separate bearings Built to handle the demanding requirements of diesel engines under load Built for Real Farm Work These Massey Ferguson tractors powered by Perkins engines are workhorses found on farms running everything from grain operations to cattle ranches. The 100 and 200 series are popular mid-range tractors perfect for operations handling 200-500 acres, while the 500 and 600 series handle heavy-duty work like deep tillage, large hay operations, and commercial farming. This crankshaft assembly also fits a wide range of Landini and Same tractors, plus industrial equipment where Perkins A4.236 and A4.248 engines do the heavy lifting. Made to Last Farm engines don't get babied, and this crankshaft is built for that reality. The forged construction handles the constant stress cycles of diesel operation, while the precision machining ensures proper oil clearances and bearing life. The flame ring design is specifically engineered for wet liner engines where the cylinder liner extends into the combustion chamber. This creates a critical seal that prevents combustion gases from leaking into the cooling system. Good to Know This is a substantial part—over 30 kilograms—so it requires freight delivery. Plan your engine rebuild accordingly and have your hoist ready. The single-bolt nose matches the original design, so you can reuse your existing pulley and damper. Take the time to check your main bearing clearances during installation, and don't forget to prime the oil system before first startup.
