Understanding the Hydraulic System on the Terex PT-110
The hydraulic system in the Terex PT-110 is responsible for driving various components, such as the lift arms, bucket, tracks, and attachments. The system relies on hydraulic fluid under pressure to transfer energy to these components, allowing for smooth and efficient operation.
The key components of the hydraulic system include:
- Hydraulic Pump: The pump generates pressure in the hydraulic system by drawing fluid from the reservoir and forcing it through the system’s lines.
- Hydraulic Cylinders: These actuators convert hydraulic pressure into linear motion, moving the loader arms, tilt, or attachments.
- Hydraulic Lines: The hoses and pipes that carry the hydraulic fluid between the pump, cylinders, and valves.
- Control Valves: These valves direct the flow of hydraulic fluid to different parts of the machine, allowing the operator to control the machine’s movements.
- Hydraulic Reservoir: This holds the hydraulic fluid, ensuring that the system remains lubricated and properly pressurized.

- Contaminated hydraulic fluid: Dirt or debris in the hydraulic fluid can cause the pump or valves to malfunction.
- Symptoms: The loader’s hydraulic functions operate erratically, with jerky movements or sudden stops during operation.
- Overheating of Hydraulic Fluid
- Symptoms: The hydraulic system overheats, which can cause the fluid to break down, leading to system failure.
- Potential Causes:
- Insufficient cooling: If the hydraulic fluid cooler is blocked or damaged, it won’t effectively dissipate heat from the system.
- Excessive load: Operating the loader under too much load for prolonged periods can cause the hydraulic system to overheat.
- Low fluid levels: Low fluid levels can lead to excessive friction in the system, causing it to overheat.
