Description
When your grain hopper door starts getting hard to crank or that familiar grinding sound tells you something’s wearing out, it’s usually this little universal joint causing the trouble. The door crank arm takes a beating opening and closing thousands of times during harvest season, and this joint is what allows that smooth rotation between the crank handle and the door mechanism. A worn joint makes door operation frustrating and can lead to bigger problems if you let it go.
What You’re Getting
- 1-inch round bore on both ends for secure shaft connection
- Heavy-duty block and pin design handles the constant rotation and side loads
- 1/4 x 1/8 inch keyway ensures positive drive without slipping
- Two 5/16-18 inch set screws lock everything in place securely
- AgSmart quality construction built for agricultural applications
Built for Real Farm Work
This joint is specifically designed to replace the worn door crank arm u-joints on Timpte grain hoppers through the 2010 model year. These hoppers see heavy use during grain harvest and hauling season, where smooth door operation is critical for efficient loading and unloading. Whether you’re running corn, soybeans, or wheat, reliable hopper doors keep your operation moving when time matters most.
Made to Last
The block and pin design is inherently stronger than needle bearing joints for this type of application. It handles the angular movement and side loads that come with door operation while resisting the dirt and debris that’s part of grain handling. The steel construction and quality manufacturing mean this joint will give you years of reliable service.
Installation Notes
This is a direct replacement for the original Timpte joint. Mark your shaft positions before removal to maintain proper door alignment. The keyways and set screws ensure everything stays tight and properly positioned. A little grease on the pin during assembly helps with smooth operation and extends service life.
