Star PTO Yoke Sizes

You've probably been wondering about star PTO yoke sizes but don't know what you should look for. Luckily, there are some things you can do to ensure your PTO yokes are as perfect as possible. First, measure the u-joints, which are located on the tractor's end of the driveline. Then, use calipers to measure the inside diameter of each yoke's ears and cap, and then compare them to the corresponding measurements on a cross and bearing identification chart.

PTO yokes come in many different sizes and shapes. You can buy them in metric and North American styles. Both have a welded connection at one end, which makes it easy to replace if the yokes wear out or break. Depending on the size of your tractor, you can select either metric or domestic yokes. Some of these yokes have female holes on the outside, which makes them suitable for a variety of applications.

Another way to choose the right PTO yoke size for your tractor is to check the tubing and shafting. A North America PTO is usually made of square/rectangle/hex/splined tubing, while metric drivelines have a bell or star-shaped tubing. You can also select the appropriate PTO shaft for your tractor with a yoke-to-yoke arrangement.

Benefits of a Quality Star PTO Yoke

As one of the leading PTO shaft manufacturers, we ensure that we produce products that allow farmers and industrial equipment operators to get the most efficiency out of their work. Our star PTO yokes include models, sizes, and features that are typically interchangeable with other manufacturers' models.

Yokes are an important part of every farm vehicle because they hold the bearings in place. The shaft or internal welded yokes are mounted on the internal shaft of the PTO line, and they play a central role in transferring power to external tools such as agricultural sprayers. We offer a variety of PTO shaft weld yokes, each with different diameters and thicknesses.

Since this star PTO yoke needs to be welded to connect properly - and the weld must be free of holes, galling or other problems that could create shear points - it is critical to choose a yoke made from quality components. We manufacture PTO assemblies using only premium materials for clean welds and long service life. Their strong attachments will ensure operator safety and drive shaft effectiveness.

Star PTO Yoke Replacement Tips

If you're in need of a star PTO yoke replacement, you've come to the right place. Here are a few tips for star PTO yoke replacement.

First, you need to identify the cause of the problem. Many issues stem from high stress or heavy loads. To find the right replacement, you need to know the specific problem. Constant compression causes the PTO shaft to break down, damaging connecting shafts and connections. In the end, this damages your tractor or implement. Fortunately, this problem can be easily fixed by shortening the shaft and reconnecting it properly. WLY can help to fix your problem.
