PTO Drive Shaft Tube PTO Shaft Tubing

You can easily distinguish a North American or a metric PTO driveline by the shape of the PTO shaft tubing. North American PTOs typically have a square or rectangular shape, while metric drivelines have a bell or star-shaped tubing. If you're unsure which one you have, check in the following. The same rule applies if you're buying a PTO for an Italian or German tractor.

For example, a finish mower with a too-short PTO shaft might have a damaged outer tube. Eventually, the inner tube would stretch to the point of bursting. Today, the tube is worn and deformed and cannot be reused. Therefore, choosing the one that fits your needs is important.

Agricultural equipment and tractors typically use a PTO shaft. High loads and stress can cause the shaft to fail. Finding the exact cause of the failure is essential to preventing damage to your tractor or implement. In many cases, constant compression of the PTO shaft causes connections to break, causing damage to the tractor or implement. Fortunately, it's relatively easy to fix the problem by reducing the length of the shaft.

During maintenance, you should check the driveline shield for loose pieces or mud. Protrusions on the driveline shaft can snag clothing and cause injuries. Also, you should check the tether to make sure it is free and secure. Always make sure the tether is in good condition and rotates freely on its bearings.

PTO Shaft Tubing Sizes and Types

Triangular PTO Shaft Tubing

The triangular style is popular for constant-velocity PTO drivelines. Here is the detailed information on triangular PTO shaft tubing at WLY.

PTO Star Tubing

If you own a large tractor or large farming equipment, the star tube PTO shaft can be an important part of the tractor. PTO star tubing shafts are usually used as tractor accessories. It will help you easily control PTO speed and torque.

Lemon PTO Shaft Tubing

There are several sizes of lemon PTO shaft tubing. Most have internal or external clasps. The clasp is usually located in a yoke or bushing. The yoke attached to the PTO shaft can be round or square. Driveline measurements can help you determine which size of lemon PTO shaft is required.

Spline Tubing

Hexagonal PTO Shaft Tube

This type of shaft is easier to install and maintain than other types of transmission systems. It is an ideal choice for tractors and other large machinery. These tubes are made of high-quality aluminum alloy and can be used for several years. Although the actual size of the driveline can vary, the following pictures should help you find the correct size.

Rectangle PTO Shaft Tubing

A power take-off shaft is the best choice for equipment that doesn't experience sudden halts. This type of PTO shaft is typically used in mowing, shredding, and plowing. For a large mower, a yoke-to-yoke arrangement can be used. If you want a shorter PTO shaft, you can also use a yoke-to-yoke arrangement.

Metric PTO Shaft Tubes

To determine whether your PTO shaft is North American or metric, you need to know the shape of the inner PTO shaft tube. If it's square or round, it's probably North American. If it's star-shaped or trilobed, it's probably Italian or German. In general, a lemon-shaped PTO shaft is made of a special alloy called 'Lemon Yellow'. However, the same alloy is used in both Italian-style and metric drivelines.

PTO Shaft Tube Replacement

Agricultural equipment wears out quickly, and PTO drive shafts are no exception. Too much angle will damage the yoke. When lubrication is insufficient, the expansion tube will also suffer excessive wear. Shielded bearings are especially prone to excessive wear if they are not adequately lubricated. Ensure that the PTO drive shaft is lubricated as often as possible to minimize its risk of failure.

There are two types of metric and domestic tubes. The domestic tube is rectangular, and the metric tube is star, bell or lemon. Then, choose the correct tube length and shape for the device. After that, you can start replacing the driveline. After selecting the proper length and shape of the tube, it is time to measure the PTO drive shaft.

How to Measure PTO Drive Shaft Tube?

How do I measure the PTO drive shaft? If you are unsure how to measure the drive shaft tube, consider the following method. Here is a guide on how to measure the PTO drive shaft tube. To determine the dimensions of the PTO drive shaft tube, find the cross shaft and bearing kit. Use calipers to measure the inside and outside diameters of the universal joint cover and yoke lugs. Simultaneously measure both sides of the cross kit tube to determine its width. The measured values are then compared with cross and azimuth recognition maps.
