That metallic tick you're hearing from the engine bay isn't something you want to ignore. When oil pressure starts dropping on your MF, it's often that little idler gear in the oil pump drive that's worn down to nothing. This kit gives you everything you need to get proper oil circulation back—a precision-cut idler gear and the circlip that keeps it where it belongs. What You're Getting Complete kit with idler gear and retaining circlip saves you a parts run Precision-cut teeth mesh smooth and quiet with your pump drive Hardened gear surface stands up to constant engine loads Direct replacement restores factory oil pump timing OEM-quality parts that fit right the first time Built for Real Farm Work Your Massey Ferguson diesel works hard whether you're pulling implements through tough ground or running a PTO for hours on end. The oil pump has one job—keep that life-giving oil flowing to every bearing and journal. When the idler gear wears out, oil pressure drops and expensive engine damage follows fast. This gear transfers power from your crankshaft to the oil pump, making sure every critical part stays lubricated under load. Made to Last This isn't a place to cut corners with cheap parts. The gear teeth are precision-machined to mesh perfectly with your existing drive components, eliminating the play that causes pressure variations. Heat-treated surfaces resist the wear that took out your original gear, while the included circlip keeps everything positioned correctly under the severe conditions inside a working diesel engine. Installation Notes You'll need to remove the timing cover to access this gear, so plan this repair during other front-end engine work. While you're in there, take a close look at the other gears in the train—a worn idler often means its neighbors need attention too. Clean all oil passages and prime the system before starting. That circlip needs to seat fully in its groove or you'll be doing this job again soon.
