Description

When your PTO starts grinding, won’t engage properly, or makes that telltale whining sound that means internal gears are wearing out, you’re looking at a hub gear that’s calling it quits. The PTO system is what transfers engine power to all your implements—from balers and mowers to brush hogs and tillers. When your loader starts moving like molasses or your three-point hitch won’t lift that heavy disc, chances are your hydraulic pump needs attention. This genuine Dynamatic pump is the same British-built quality that came on your tractor from the factory, engineered specifically for the closed-center load sensing (CCLS) systems on SLE-equipped 40 Series and TS tractors. This hub gear keeps that power transfer smooth and reliable, so you can count on your implements when the work needs doing.

What You’re Getting

Precision-machined gear teeth that mesh properly with your PTO gearbox for smooth power transfer
Heat-treated steel construction that stands up to the constant torque loads of implement operation
Factory specifications that ensure proper fit and function with your existing PTO components
Direct replacement part—no modifications or adapters needed for installation

Built for Real Farm Work

Suitable for Ford New Holland 40 Series tractors including 5640, 6640, 7740, 7840, 8240, and 8340 models, as well as TS Series models TS80, TS90, TS100, TS110, and TS115. These mid-range tractors are the workhorses of many farming operations, handling everything from hay production and livestock work to row crop farming and loader duty. Whether you’re running a 64-horsepower 5640 on a smaller operation or pushing a big 8340 through heavy fieldwork, this gear is engineered for the demanding conditions these tractors face.

Made to Last

PTO gears take a beating—they handle the shock loads from engaging implements, the constant torque of heavy equipment, and the vibration that comes with farm work. This hub gear is manufactured to the same standards as the original equipment, using quality steel that’s heat-treated for durability. It’s built to handle the power output of these tractors without premature wear or failure.

Installation Notes

Replacing a PTO hub gear typically requires splitting the tractor to access the gearbox, so this is definitely a job for someone with mechanical experience and the right tools. Pro installation tips: When installing this pump, always use a new gasket (part 3862) and fresh, clean hydraulic oil. The CCLS system is sensitive to contamination, so flush the entire system if your old pump failed internally. While you’ve got the PTO apart, it’s a good time to inspect other internal components and replace any seals that might be showing wear. Take your time and follow proper torque specifications—a PTO failure in the middle of harvest season is something you definitely want to avoid.
