Hydraulics are one of the main pieces of equipment inside a heavy-duty truck. This powerful equipment can move impressive weights and is behind some of the truck’s most vital tasks.
Due to their needs or vital role in handling heavy shipments, a working and maintained hydraulic system is critical. Without a properly working hydraulic system you will definitely lose efficiency and may lead to accidents.
To maintain the Hydraulics of your heavy-duty truck, stick to your scheduled maintenance, as the manufacturer recommends. It includes checking fluid levels, inspecting hoses and fittings for leaks or damage, and replacing filters and fluids as needed.

Top 5 Maintenance Tips From Experts For Your Heavy-Duty Truck Hydraulics:

1. Regular Inspections Are Crucial

You must check your hydraulic system frequently. Ensure the fluid is at the right level, there are no leaks, and all components work seamlessly. Visual inspection is the key. If you find anything unusual, contact SRB Equipment.

2. Change Hydraulic Fluid Regularly

Old fluid can degrade the hydraulic system’s performance. It forces the system to work hard, even for small jobs. Regular oil changes improve your hydraulic system’s performance, extend longevity, and help your truck achieve peak power. They also keep all the engine controls properly lubricated and running smoothly.

3. Clean The System

Contaminants such as dirt and road chemicals pose significant threats to the performance and longevity of hydraulic systems in heavy-duty trucks. Regular cleaning of hydraulic filters for heavy trucks is essential to prevent contaminants from infiltrating critical components, safeguarding optimal performance.

4. Contact The Hydraulic Repair Shop When Needed

Contacting a hydraulic system repair professional is paramount when the repair tasks require specialized knowledge and equipment. Attempting to tackle complex hydraulic repairs without the necessary skills can worsen the problem and potentially endanger the vehicle. So, contacting a heavy duty truck mechanic is necessary.

5. Use Quality Parts

Don’t sacrifice your truck’s hydraulic system with low-quality parts. This is not the right place to save your money. Otherwise, saving a little money today will cost you a huge breakdown tomorrow. Investing in high-quality components for longevity and peak performance of the hydraulic system is always recommended.

Here Are Top 5 Common DIY Heavy Duty Truck Hydraulic System Repair

1. The tipper body is not moving up

Certain reasons can cause your tipper to be stuck and not move up. The reasons could be low hydraulic fluid, a faulty pump or motor, or a dead battery.
To address this situation, you can try certain techniques. First, check the fluid level. If it is low, you must add hydraulic fluids. Ensure the fluid level is at least halfway up the hydraulic tank level. You must also free the air in the system. Open the relief valves until you don’t find air bubbles in the fluid. If there is a suction filter in the tank, it may have become clogged, making the pump less efficient. Cleaning the pump suction strainer ensures a free oil flow to the pump.

2. The tipper’s body moves up very slowly

A weak battery can affect tipper lifting power. You can charge the battery or fix the loose cables or wires to handle this situation. However, consider replacing the battery only after consulting a heavy duty truck hydraulic system maintenance professional. They can assess whether the battery is the root cause of the issue or if there are other underlying problems affecting the hydraulic system’s performance.

3. Hydraulic fluid Is leaking

Troubleshooting leaks in a heavy duty truck hydraulic system is easy. Operate the hydraulic system and check for leaks in all pipes, hoses, valves, pump connections, and cylinders. If nothing is found, check for the surface of the hoses. It may rust due to a damaged hose cover, leading to oil weeping. It is common when hoses are exposed to road salt spray. If you can’t find the problem, search for a heavy duty truck hydraulic system repair professional and get their services.

4. Repair a hydraulic cylinder

Repairing a hydraulic cylinder on a heavy duty truck depends on many factors. If all the parts of the hydraulic cylinder are in good condition, then a hydraulic seal replacement should do the job.
You can also try one more thing. You can remove the cylinder, clean it, and measure it to rebuild it. If all the parts are in serviceable condition, this should stop a hydraulic cylinder from leaking.

5. The tipper is stuck in a particular position.

You can do some tests or procedures, such as pressing the override button in the valve. If pressing this button allows the tipper to descend, it probably means the coil is burnt out. To check the coil, take a steel screwdriver near it. If the coil is energized, it will attract the screwdriver. If the coil is magnetic, the problem may be with the valve itself. If it doesn’t, you should replace the coil.
If controlled by a solenoid or manual valve, check for blockages or damage in the circuit, including check valves, one-way restrictors, and quick-release couplings, which can cause oil flow issues. If the manual spool valve is stuck, inspect the linkage for damage. If needed, seek professional assistance from professionals in hydraulic system maintenance for trucks.

What Things Should You Consider When Buying Hydraulic Fluid For Heavy Trucks?

  • Choose a hydraulic fluid with the appropriate viscosity grade.
  • Determine whether your truck’s hydraulic system requires mineral-based, synthetic, or bio-based hydraulic fluid.
  • Consider your truck’s operating conditions, including temperature extremes, heavy loads, and frequent use.
  • Follow the recommendations of hydraulic fluid manufacturers and consult with experienced professionals if you need help deciding which fluid to choose.
