Triangular PTO Shaft Disassembly



1. Remove the safety shield.
2. Shorten the inner and outer tubes according to the required length, and the inner and outer tubes shall be shortened by the same length at one time
3. Deburr edges of the drive tubes with a file and remove all filings from the tubes.
4. Shorten the inner and outer plastic pipes according to the required length, and the inner and outer plastic pipes shall be shortened by the same length at one time.
5. Grease the internal drive tubes and reassemble them with a safety shield.
Check the minimum and maximum length of the driveshaft installed on the machine. In working condition, the drive tubes should overlap 2/3 length and the plastic tube should never be separated

How to Shorten a Triangular Pto Shaft


Frequent lubrication is required. Grease the driveline shaft parts at hourly intervals as indicated on the drawing left.Lubrication of Triangular PTO Shaft

The same assembly method is used for both types of safety shields.

PTO Shaft for Agricultural Gearboxes

Agricultural gearbox and PTO shaft work together to transfer mechanical power between farm tractors. A PTO shaft converts engine energy into hydraulic pressure. This is what allows the tractor to pull heavy loads. When properly functioning, it reduces the risk of damage to the tractor and to the operator. When used properly, it is an important component of a tractor, but it can also become defective. When choosing an agricultural gearbox, consider the durability and mechanism of the product, as well as its materials. A durable gearbox will last for many years, avoiding repeated replacements. A high-quality agricultural gearbox will be durable for many years to come, and you don’t want to end up replacing it for a while. This can be costly, so consider your needs when purchasing an agricultural gearbox and PTO shaft.
