Automotive Lift Repair Orlando | How to Make Hydraulic Hoses

How to Make Your Own Hydraulic Hose

After creating the inner tube, it’s time to add reinforcement. We use stainless steel wire to form the hydraulic hose reinforcement layers. There are two primary methods for this:

Automotive Lift Repair Orlando Braided Hydraulic Hose: A braiding machine weaves stainless steel wire into the reinforcement layers. Multiple layers can be applied; for instance, we offer 2-layer and 4-layer options, including 2-wire and 4-wire braided hydraulic hoses.

Automotive Lift Repair Orlando Spiral Hydraulic Hose: A spiral machine wraps the stainless steel wire in a spiral formation to create the reinforcement. This includes options such as 4-wire and 6-wire spiral hydraulic hoses.

Step 5: Extrude the Outer Cover

Once the wire reinforcement is complete, we extrude synthetic rubber to form the outer cover of the hydraulic hose. The outer cover can have different surface finishes, such as smooth or wrapped. Wrapped covers are particularly popular. Here’s a comparison between smooth and wrapped hydraulic hoses.

Step 6: Vulcanize the Hydraulic Hose

The Automotive Lift Repair Orlando hydraulic hose is then vulcanized in a specialized boiler. Steam heating cures the rubber material, causing the rubber molecules to bond more tightly, which ensures stable performance of the hydraulic hose.

Measuring Hydraulic Hose

To measure a hydraulic hose, follow these guidelines:

1. Measure Hose Length: Use a stainless steel ruler or tape measure. The length is crucial for routing and assembling the hose.

2. Measure Hose Diameter: Use a vernier caliper to measure the internal diameter (ID) and outer diameter (OD) of the hose. The thickness can be calculated using the formula: Thickness = OD – ID.

Cutting Hydraulic Hose

Here’s how to cut a hydraulic hose:

1. Determine the desired length.

2. Choose an appropriate cutting machine.

3. Follow the manufacturer’s instructions for the cutting tool.

4. Clean the hose before cutting.

5. Position the hose under the cutting blade or saw, ensuring it’s vertical to the blade.

6. Make the cut.

Removing Automotive Lift Repair Orlando Hydraulic Hose Fittings

To remove hydraulic hose fittings for replacement or repair:

1. Turn off the Automotive Lift Repair Orlando hydraulic system.

2. Use the correct wrench to loosen the fittings. Most have two couplings, so clamp one wrench on one coupling and use another wrench to turn the other coupling.

3. Applying lubricant oil can ease the removal process. Turn the wrench counterclockwise to loosen the fittings.

Repairing Hydraulic Hose

Follow these steps for repairing a hydraulic hose:

1. Identify the correct hydraulic hose.

2. Remove the damaged hose.

3. Seal the new hose.

4. Check the hose pressure.

Crimping a hydraulic hose is a vital part of hose assembly, as it ensures the hose performs reliably under pressure and movement. A precise crimp is essential to avoid damaging the application. Here’s a step-by-step guide for crimping a hydraulic hose properly:

Step 1: Measure and Cut the Hose  

Determine the required length of the hose and cut it to size using a hose saw.

Step 2: Select the Fitting Series  

Choose the fitting series based on factors like working pressure, style, type, orientation, attachment methods, and corrosion resistance.

Step 3: Mark Insertion Depth and Install Fittings  

Use a hose insertion depth block to mark the correct insertion depth for the fitting. This mark will help ensure the fitting is properly seated on the hose.

Step 4: Set the Crimp Specifications  

Adjust the crimp diameter settings on the crimp machine according to the specifications for each hose assembly.

Step 5: Choose the Die  

Select the appropriate crimper die designed for the specific hose and fitting. Verify that the die is set to the correct specifications.

Step 6: Insert the Hose into the Crimping Machine  

Place the hose end into the Automotive Lift Repair Orlando crimping machine (usually bottom loading) and through the die so that the fitting extends above the die. Ensure the top of the hose, which is now inside the fitting, does not extend above the die.

Step 7: Crimp the Hose  

Start the crimping process by turning on the machine. The cylinder head will descend slowly, compressing the collar and die. Avoid touching the machine until the collar is firmly at the bottom of the die, at which point the machine should stop automatically.

Step 8: Check the Crimp Diameter  

Inspect the chalk mark on the hose. If it’s not at the base of the fitting, the hose or fitting may have shifted during crimping. This indicates an improper crimp. If the mark is in place, the crimp is successful. Measure the crimp diameter on a flat surface of the crimped shell and compare it to the diameter specified on the decal. Do not use assemblies with incorrect crimp diameters.

Step 9: Clean the Hose Assembly  

Remove contaminants from the hose, especially if it’s a larger diameter. Use a hose brush, compressed air, or projectile pellets for cleaning.

Step 10: Cap the Hose Assembly  

Once cleaned, cap both ends of the hose assembly using plastic or heat shrink caps to prevent contamination.

Following these steps will help you achieve a properly crimped and reliable hydraulic hose assembly.

What is Hydraulic Hose Assembly?

A Automotive Lift Repair Orlando hydraulic hose assembly involves attaching fittings to both ends of a hose pipe, allowing it to connect with machines and systems. This setup facilitates the transfer of media or fluid from one end of the hose to the other.

Based on our extensive experience, we understand that there isn’t a one-size-fits-all guide for hydraulic hose assemblies due to the complexities and varying environmental conditions involved. However, some fundamental steps are common across most assemblies.

We’ve compiled these common steps into a comprehensive guide to hydraulic hose assembly for beginners.
