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.

When your engine starts knocking like there's a hammer loose in the block, you know it's rebuild time. This heavy-duty replacement crankshaft is the heart of your Perkins 1004.40 engine rebuild, converting all that diesel combustion into the power that gets your work done. Whether you've got worn journals, spun bearings, or discovered cracks during maintenance, this forged crank gets your engine back to earning its keep instead of taking up valuable shop space. What You're Getting Direct OEM replacement for both 1004.40 Blue and 1004.40TW Green engine variants Heavy-duty forged construction that weighs over 66 pounds - built to handle serious workloads Precision-ground journals deliver smooth operation and extend bearing life Matches original specifications perfectly for proper fit with existing components Ships freight due to weight - plan your delivery timing accordingly Built for Real Farm Work These Perkins 1004.40 engines power countless Massey Ferguson, Case, and other tractors that form the backbone of working farms across the country. From field cultivation to heavy loader work, these engines take incredible punishment spinning thousands of times per minute while handling combustion forces that would destroy lesser components. This replacement crank uses the same forging process and heat treatment that made Perkins famous for reliability. Made to Last Quality matters when you're this deep into an engine rebuild. This forged crankshaft features the same metallurgy and manufacturing standards as the original Perkins part, ensuring it can handle the stress of heavy fieldwork for years to come. The precision-ground journals provide the proper surface finish for optimal bearing contact and oil film retention. Good to Know A crankshaft replacement means you're committed to a complete rebuild - make it count. Have your machine shop check the new crank's dimensions and verify bearing clearances before assembly. Clean the block thoroughly, check for cracks, and consider having it bored if needed. Pre-lube all bearings with assembly paste during installation, follow proper torque sequences, and check end play. With quality parts like this and careful assembly, you'll get another generation of reliable service from that trusty tractor.
