When you're dealing with a knocking engine or excessive vibration in your Massey Ferguson, it's often the crankshaft that's calling it quits. This is the heart of your engine - the part that converts the power from your pistons into the rotational force that gets your work done. If your tractor won't start smooth or sounds rough at idle, a worn crankshaft might be the culprit. What You're Getting Complete crankshaft with keyed nose for easy pulley installation Rope seal design that works with original engine specifications Precision-balanced shaft reduces vibration and extends bearing life Machined bearing journals to exact specifications for proper oil clearance Built to handle the demands of agricultural and industrial applications Built for Real Farm Work This crankshaft fits Massey Ferguson tractors from the reliable 65 series up through the hardworking 100 and 200 series models, plus it's compatible with Landini Prima series and various telehandlers powered by Perkins A4.203 and A4.192 engines. Whether you're running a compact utility tractor for livestock work or a mid-size machine for row crop farming, these engines are known for their dependability in everything from loader work to heavy tillage. Made to Last This crankshaft is built to the same specifications as the original Perkins part. The steel is heat-treated for strength and durability, while the bearing surfaces are precision-ground to ensure proper oil film thickness. The rope seal design matches what came in your engine from the factory, so you know it'll seal properly without modifications. Good to Know This is a major engine rebuild component that requires proper tools and experience. You'll need to check bearing clearances and ensure proper torque specifications during installation. The keyed nose makes timing gear and pulley installation straightforward, but take your time with the assembly - a properly rebuilt engine with this crankshaft can give you many more years of reliable service.
