Hydraulic hammers are invaluable tools for breaking rock, concrete, and other tough materials in heavy construction and demolition projects. Okada is a well-known brand in the industry, offering robust hydraulic hammers designed for high-performance tasks. However, like any piece of equipment, even Okada hammers can run into problems, leaving operators frustrated and unsure of how to proceed.
One of the most common issues operators face is when the hammer stops working or malfunctions unexpectedly. If your Okada hammer isn’t working, it’s essential to understand the potential causes behind the failure, troubleshoot the issue effectively, and take the necessary steps to restore its functionality.
In this article, we will explore some of the common issues that can affect Okada hydraulic hammers, how to troubleshoot them, and steps you can take to avoid these problems in the future.
Understanding Okada Hydraulic Hammers: How They Work
Hydraulic hammers, or breakers, like the Okada models, rely on the hydraulic system of the carrier equipment (e.g., a skid steer or excavator) to operate. These hammers use the power from hydraulic pressure to create a rapid, forceful impact, breaking through solid materials. The hydraulic hammer’s function depends on various components working together, including:

Understanding Okada Hydraulic Hammers: How They Work
Hydraulic hammers, or breakers, like the Okada models, rely on the hydraulic system of the carrier equipment (e.g., a skid steer or excavator) to operate. These hammers use the power from hydraulic pressure to create a rapid, forceful impact, breaking through solid materials. The hydraulic hammer’s function depends on various components working together, including:
- Hydraulic fluid and pressure.
- Piston and cylinder components to generate impact force.
- Accumulator for storing hydraulic energy.
- Control valves that regulate the flow and pressure.
Common Issues with Okada Hydraulic Hammers
- Hammer Fails to Fire or Operate:
- Symptoms: If your Okada hammer isn’t firing, or if it operates intermittently, it could be due to a variety of issues, including insufficient hydraulic pressure, worn-out seals, or problems with the internal components.
- Potential Causes:
- Low hydraulic fluid levels or air in the hydraulic lines.
- A malfunctioning control valve or solenoid that regulates fluid flow.
- Damaged piston or internal components causing a lack of impact force.
- Low hydraulic fluid levels or air in the hydraulic lines.
- Symptoms: If your Okada hammer isn’t firing, or if it operates intermittently, it could be due to a variety of issues, including insufficient hydraulic pressure, worn-out seals, or problems with the internal components.
- Hammer Operates Slowly:
- Symptoms: A hydraulic hammer that operates slowly and with less force may struggle to break through materials. This issue is often linked to inadequate hydraulic flow or pressure.
- Potential Causes:
- Hydraulic fluid contamination or improper fluid levels.
- Clogged filters in the hammer or the carrier machine.
- Malfunctioning pressure relief valve affecting fluid flow.
- Hydraulic fluid contamination or improper fluid levels.
- Symptoms: A hydraulic hammer that operates slowly and with less force may struggle to break through materials. This issue is often linked to inadequate hydraulic flow or pressure.
- Hammer Jams or Clogs:
- Symptoms: If the hammer is jamming or failing to cycle, this could indicate a blockage within the hydraulic hammer itself.
- Potential Causes:
- Dirt or debris in the hydraulic system.
- Internal piston failure or worn-out components.
- A damaged accumulator or issues with the hammer’s internal seals.
- Dirt or debris in the hydraulic system.
- Symptoms: If the hammer is jamming or failing to cycle, this could indicate a blockage within the hydraulic hammer itself.
- Excessive Vibration or Noise:
- Symptoms: Excessive vibration or unusual noise during operation is another sign that something is wrong with the hammer.
- Potential Causes:
- Low hydraulic pressure or fluid contamination leading to poor lubrication and excessive friction.
- Loose bolts or damaged housing causing abnormal movement.
- Worn-out hammering components such as the chisel, piston, or anvil.
- Low hydraulic pressure or fluid contamination leading to poor lubrication and excessive friction.
- Symptoms: Excessive vibration or unusual noise during operation is another sign that something is wrong with the hammer.
If your Okada hydraulic hammer is not working as expected, follow these troubleshooting steps to identify and address the issue:
- Check Hydraulic Fluid Levels:
- Ensure that the hydraulic fluid is at the proper level and that it’s clean. Low fluid levels can cause the hammer to lose power or fail to cycle properly. Contaminated fluid can also damage internal components.
- Solution: Top off the hydraulic fluid and replace any old, dirty fluid with the manufacturer-recommended type.
- Ensure that the hydraulic fluid is at the proper level and that it’s clean. Low fluid levels can cause the hammer to lose power or fail to cycle properly. Contaminated fluid can also damage internal components.
- Inspect for Leaks or Damaged Hoses:
- Inspect the hydraulic hoses for signs of leaks or damage. Leaks in the system can cause a drop in hydraulic pressure, which may prevent the hammer from operating correctly.
- Solution: Replace any damaged hoses or fittings to restore proper hydraulic pressure.
- Inspect the hydraulic hoses for signs of leaks or damage. Leaks in the system can cause a drop in hydraulic pressure, which may prevent the hammer from operating correctly.
- Bleed the Hydraulic System:
- Air in the hydraulic lines can cause irregular or erratic hammering action. Ensure the system is free of air by bleeding the system.
- Solution: Follow the manufacturer’s instructions for bleeding the hydraulic system and eliminating air pockets.
- Air in the hydraulic lines can cause irregular or erratic hammering action. Ensure the system is free of air by bleeding the system.
- Inspect the Control Valve and Solenoid:
- The control valve and solenoid regulate the flow of hydraulic fluid to the hammer. If these components are faulty or clogged, the hammer will not receive the proper fluid pressure.
- Solution: Test the control valve and solenoid, and clean or replace them if necessary.
- The control valve and solenoid regulate the flow of hydraulic fluid to the hammer. If these components are faulty or clogged, the hammer will not receive the proper fluid pressure.
- Examine Internal Components for Damage:
- If the hammer fails to fire or operates slowly, it could be due to worn-out internal components such as the piston, chisel, or anvil. These parts are subject to wear due to the repetitive impacts they endure.
- Solution: Inspect the hammer for worn parts and replace any components that are damaged or excessively worn.
- If the hammer fails to fire or operates slowly, it could be due to worn-out internal components such as the piston, chisel, or anvil. These parts are subject to wear due to the repetitive impacts they endure.
- Check the Accumulator and Piston:
- The accumulator stores hydraulic pressure and ensures that the hammer delivers consistent impact force. A malfunctioning accumulator or piston can result in reduced hammering force or a hammer that doesn’t fire.
- Solution: Test the accumulator for leaks or loss of pressure. If it’s damaged, replace it. Similarly, inspect the piston for wear and replace it as needed.
