Hydraulic oil spills over the neck, motor, makes no force. What is caused by?

Hydraulic motor neck spill oil. What's caused?

Let's analyze this. There are a lot of problems for users who bring them in.

Orbit Motor is a common symptom. If left, it will cause oil leakage, loss of pressure, inefficient system, and even heavier motor damage.

The main reason for the oil spilling over the neck

1. Shaft neck seal is felt or expired. It is the most common cause. When the seal is hard, torn or deteriorated with service life, it will not be able to retain oil, causing oil to leak out in the shaft neck.

2. Bushing or feel shaft. When the bushing or bearing is felt, the shaft will be cloned. Even if the new seal is replaced, it will leak because the seal cannot be attached to the shaft.

3. The pressure inside the motor is unusually high. If the drain pipe (Case Drain) clogs or the system has a high reverse pressure, it will push the oil out through the seal until the oil spills over the neck.

4.Dirty hydraulic oil, dirt, scrap metal or oil contaminants will accelerate the wear of seals, bushings and internal parts, causing motor damage faster than usual.

5. Incorrectly installed. Installing a stiff shaft, indentation or misaligned joint will cause the seal to bear too much force until a leak occurs in a short time.

How to prevent

✅. Check seals and leaks regularly.

✅ Change the oil and filter by range.

✅ Use clean and standardized hydraulic oil.

✅ Check the Case Drain system not to clog.

✅ Check the system pressure not to exceed the manufacturer's specified value.

✅ Check the installation of axles and joints to match the V-Tek line.

✅ If you start seeping oil, you should fix it quickly. Don't let it leak.

Summary

Hydraulic motor neck spilling oil is not caused by waste seals alone, but mainly by degenerative seals, bushings or felt bearings, cloning shafts, high internal pressure, and dirty hydraulic oil. If checked and maintained regularly, it will prolong the life of the motor, reduce repair costs, and effectively prevent the cessation of machinery.
