how to change hydraulic hose on excavator | Passionhose

Hydraulic hoses are vital components in the operation of an excavator. They transmit hydraulic power from the machine to various attachments, allowing for efficient operation. However, over time, these hoses can become worn, damaged, or develop leaks, necessitating their replacement. In this article, we will discuss how to change hydraulic hoses on an excavator, a task that can be easily performed with the right tools and knowledge.

Gather the Necessary Tools

Before you begin the process of changing a hydraulic hose on your excavator, it is essential to gather all the necessary tools and materials. You will need a new hydraulic hose of the appropriate size and length, as well as any fittings or couplings required for installation. Additionally, you will need a wrench or socket set, a bucket to catch any spilled hydraulic fluid, safety goggles, and gloves to protect yourself from coming into contact with hydraulic fluid.

Once you have gathered all the necessary tools, you can proceed with changing the hydraulic hose on your excavator.

Locate the Damaged Hose

The first step in changing a hydraulic hose on an excavator is to locate the damaged hose. Inspect the hydraulic system for any visible signs of damage, such as bulges, abrasions, or leaks. Trace the path of the hoses from the hydraulic pump to the attachment to identify the hose that needs to be replaced.

Once you have located the damaged hose, you can proceed with removing it from the excavator.

Remove the Old Hose

Before removing the old hydraulic hose, it is essential to relieve pressure from the hydraulic system. Start by shutting off the engine of the excavator and engaging the safety lock to prevent accidental startup. Then, operate the hydraulic controls to move the attachment to a neutral position, relieving pressure from the system.

Next, use a wrench or socket set to loosen the fittings connecting the damaged hose to the hydraulic system. Be prepared for some hydraulic fluid to spill as you disconnect the old hose. Place a bucket underneath the hose to catch any spilled fluid and dispose of it properly.

Once you have removed the old hydraulic hose, you can proceed with installing the new hose on your excavator.

Install the New Hose

To install the new hydraulic hose on your excavator, start by applying hydraulic fluid to the fittings to ensure a proper seal. Then, carefully thread the new hose into place, making sure not to cross-thread the fittings. Use a wrench or socket set to tighten the fittings securely, but be careful not to over-tighten them, as this can cause damage to the hose or fittings.

Once the new hose is in place, double-check all connections to ensure they are secure. Start the engine of the excavator and operate the hydraulic controls to test the new hose for leaks or other issues. If everything is working correctly, you have successfully changed the hydraulic hose on your excavator.

Maintain Your Hydraulic System

After changing the hydraulic hose on your excavator, it is essential to regularly inspect and maintain your hydraulic system to prevent future issues. Check all hoses, fittings, and connections for signs of wear or damage and replace any components that show signs of wear.

Additionally, be sure to use the correct type of hydraulic fluid for your excavator and regularly top up the fluid levels as needed. Proper maintenance of your hydraulic system will ensure the continued reliable operation of your excavator.

In conclusion, changing a hydraulic hose on an excavator is a task that can be easily accomplished with the right tools and knowledge. By following the steps outlined in this article, you can effectively replace a damaged or worn hydraulic hose on your excavator and ensure the continued efficient operation of your machine. Remember to always prioritize safety when working on hydraulic systems and consult a professional if you are unsure of how to proceed.
