Understanding the Steering System of the Hough H-70 Loader
Before delving into common steering issues, it’s essential to understand the components involved in the steering system of the Hough H-70 loader. The steering system in the H-70 is typically hydraulic, utilizing a combination of hydraulic pumps, steering cylinders, and valves to turn the loader’s wheels smoothly and efficiently.
Common Steering Issues in the Hough H-70 Loader
Several steering-related problems are commonly reported by Hough H-70 operators. These include difficulty turning the steering wheel, poor response when turning, and complete steering failure. Here are some of the most frequent causes:
1. Low Hydraulic Fluid Levels
When faced with steering problems on the Hough H-70 loader, it’s important to follow a systematic troubleshooting approach. Here’s a step-by-step guide:
To minimize the occurrence of steering problems, regular preventive maintenance is essential. Here are some tips to help keep the steering system in top shape:
A contractor using a Hough H-70 loader on a road construction project noticed that the loader was becoming increasingly difficult to steer. The operator struggled to turn the steering wheel, and when they did manage to turn, the response was slow and unresponsive. After checking the hydraulic fluid, they found it was significantly low. They topped off the fluid and found a small leak near the steering cylinder. Once the leak was sealed and the fluid topped off, the steering returned to normal, and the loader was able to perform as expected.
This case underscores the importance of checking fluid levels and sealing hydraulic system leaks. Regular maintenance can prevent such issues from escalating and keep your machine running smoothly.
Conclusion
Steering problems in the Hough International H-70 loader can arise due to a variety of reasons, from low hydraulic fluid levels to faulty pumps and worn-out steering cylinders. Understanding the common causes and following a step-by-step troubleshooting approach can help operators quickly diagnose and resolve these issues, minimizing downtime and maximizing productivity.
By adhering to regular maintenance practices, such as fluid checks, filter replacements, and hose inspections, you can keep the steering system functioning properly for years to come. Whether you're using the H-70 for construction, demolition, or material handling, maintaining its steering system is crucial for ensuring smooth operation on the job site.

Understanding the Steering System of the Hough H-70 Loader
Before delving into common steering issues, it’s essential to understand the components involved in the steering system of the Hough H-70 loader. The steering system in the H-70 is typically hydraulic, utilizing a combination of hydraulic pumps, steering cylinders, and valves to turn the loader’s wheels smoothly and efficiently.
- Hydraulic Pump: The pump provides pressurized hydraulic fluid to the steering cylinders, allowing for the smooth turning of the loader’s wheels.
- Steering Cylinders: These cylinders are responsible for applying the force needed to turn the wheels based on the hydraulic fluid pressure supplied by the pump.
- Steering Valve: The steering valve directs the hydraulic fluid to the correct side of the steering cylinders, facilitating movement in either direction.
Common Steering Issues in the Hough H-70 Loader
Several steering-related problems are commonly reported by Hough H-70 operators. These include difficulty turning the steering wheel, poor response when turning, and complete steering failure. Here are some of the most frequent causes:
1. Low Hydraulic Fluid Levels
- Cause: One of the most common reasons for steering issues in the H-70 loader is low hydraulic fluid levels. Hydraulic fluid is essential for the proper operation of the steering cylinders, and if the fluid level drops too low, the steering system can become unresponsive or difficult to maneuver.
- Solution: Check the hydraulic fluid levels regularly, and top off as needed. Be sure to use the recommended type of hydraulic fluid, and replace any old or contaminated fluid. If the fluid is low frequently, inspect the hydraulic system for leaks.
- Cause: Air trapped in the hydraulic system can cause inconsistent steering or make the steering feel sluggish. Air can enter the system through leaks in hoses, fittings, or the pump itself, causing bubbles to form in the fluid, which reduces the efficiency of the steering system.
- Solution: Bleed the hydraulic system to remove any air pockets. This process involves opening the bleeder valves on the steering cylinders to allow air to escape while the pump runs. Ensure that all hoses and fittings are properly sealed to prevent air from entering the system.
- Cause: A malfunctioning hydraulic pump can result in low or inconsistent fluid pressure, which will prevent the steering cylinders from functioning properly. This could be due to wear and tear on the pump components, internal damage, or contamination in the pump.
- Solution: Inspect the hydraulic pump for any visible signs of damage or wear. Test the pump’s output pressure using a pressure gauge. If the pump is not delivering the proper pressure, it may need to be rebuilt or replaced.
- Cause: Over time, the steering cylinders or their seals may wear out, leading to hydraulic fluid leakage. This can result in a lack of steering force, making it difficult to turn the loader.
- Solution: Inspect the steering cylinders for visible signs of damage, such as leaks around the seals or corrosion on the cylinders. If the seals are damaged, replace them. In severe cases, the entire steering cylinder may need to be replaced.
- Cause: The steering valve is responsible for directing hydraulic fluid to the appropriate side of the steering cylinders. If the valve malfunctions, the fluid may not flow properly, resulting in unresponsive steering or difficulty turning.
- Solution: Inspect the steering valve for any signs of blockage or damage. Clean or replace the valve if necessary. It’s also essential to check that the valve’s internal components are free from debris or corrosion that may hinder its operation.
- Cause: Hydraulic filters are designed to prevent contaminants from entering the hydraulic system. If the filters become clogged with dirt or debris, they can restrict fluid flow, leading to poor steering performance.
- Solution: Check the hydraulic filters and clean or replace them as needed. Regularly changing the filters will help maintain optimal fluid flow and prevent contamination from affecting the steering system.
