You know that annoying vibration coming from the PTO shaft or pump drive? That’s your equipment telling you it’s time for a new coupling. When shafts don’t line up perfectly—and let’s face it, they rarely do—a good flexible coupling smooths things out and keeps your equipment running without the shake, rattle, and premature wear that’ll cost you down the road.
What You’re Getting
- Maintenance-free design that doesn’t need regular greasing or lubrication
- Durable cast iron construction that handles the torque and vibration of farm equipment
- Hollow head setscrews provide a secure grip on 1/2-inch shafts without slipping
- Flexible design compensates for minor shaft misalignment and reduces shock loads
Where This Part Shines
This L90 series coupling body end is perfect for connecting pump drives, PTO applications, and other rotating equipment where you need reliable power transfer with some forgiveness for alignment issues. It’s commonly used on smaller tractors, utility equipment, and stationary engines where 1/2-inch shaft connections are standard. Whether you’re running an irrigation pump, feed mixer, or shop equipment, this coupling keeps things turning smoothly.
Made to Last
Farm equipment doesn’t get babied, and this coupling is built to handle it. Made of sintered iron or cast iron that won’t crack under stress, and the maintenance-free design means one less thing to remember during busy seasons. The flexible spider design absorbs shock loads that would otherwise stress your bearings and shaft connections.
Good to Know
2 coupling body ends and 1 spider are required for a complete coupling assembly. This is just one half of the complete coupling—you’ll need another body end and a spider to finish the job. Make sure your shafts are clean and properly aligned before installation, and check the setscrew tightness after the first few hours of operation.
