How to Bleed Hydraulic System on Valtra Tractor - Step-By-Step Guide

If you own a Valtra tractor and are experiencing issues with your hydraulic system, it may be necessary to bleed the system in order to remove air bubbles or other contaminants. Bleeding the hydraulic system can help restore proper functionality and ensure smooth operation. In this step-by-step guide, we will walk you through the process of bleeding the hydraulic system on your Valtra tractor.

1. Identify the Bleed Points

Start by locating the bleed points on your Valtra tractor. These are typically located on the hydraulic cylinders or valves that are part of the system. Refer to your Valtra tractor's user manual or consult with a qualified technician to identify the exact location of the bleed points.

2. Prepare the Tractor

Before starting the bleeding process, ensure that the tractor is turned off and parked on a level surface. Engage the handbrake and switch off the engine. This will minimize any risks when working on the hydraulic system.

3. Gather Required Tools

Make sure you have the necessary tools and equipment to complete the bleeding process. Commonly required tools include a wrench, hose, container, and suitable protective gloves. Prepare these items before moving forward with the procedure.

4. Begin Bleeding

There are various methods to bleed a hydraulic system, and the technique may vary depending on the specific Valtra tractor model. Here, we will discuss a general approach:

1. Locate the bleed valve on the hydraulic cylinder or valve, and using a wrench, loosen it to open the valve.
2. Attach a hose to the bleed valve, ensuring it is securely connected.
3. Place the other end of the hose into a suitable container to collect the hydraulic fluid.
4. Gradually open the bleed valve. As the valve is opened, the air or contaminants within the system should start to be released through the hose and into the container. Keep an eye on the fluid flow and ensure it is free of air bubbles.
5. Continue this process until a steady flow of hydraulic fluid is achieved without any air bubbles. This indicates that the system has been thoroughly bled.
6. Once the bleeding process is complete, close the bleed valve tightly to prevent any leakage.
7. Inspect the hydraulic system for any signs of leakage or damage. Address any issues promptly before operating the tractor.

5. Test the Hydraulic System

After bleeding the hydraulic system, it is crucial to test its functionality before resuming regular use of the Valtra tractor. Start the engine and operate the hydraulic system through its full range of motion to ensure it is working properly. Pay attention to any abnormal sounds or problems that may require further attention.

6. Properly Dispose of Hydraulic Fluid

Hydraulic fluid used during the bleeding process may contain air bubbles or contaminants, rendering it unsuitable for further use. Ensure to dispose of the collected hydraulic fluid appropriately, adhering to local environmental regulations.

Always refer to the Valtra tractor's user manual for specific instructions and recommendations regarding bleeding the hydraulic system. If you are uncertain about any step or encounter difficulties, it is advisable to consult with a qualified mechanic or contact the Valtra customer support for assistance.

By following this step-by-step guide and taking necessary precautions, you should be able to successfully bleed the hydraulic system on your Valtra tractor, ensuring its optimal performance and longevity.
