The Case 1845C is a popular skid steer loader widely used in construction, agriculture, and landscaping due to its versatility and durability. One of the features that sets the 1845C apart is its auxiliary hydraulic system, which powers attachments like augers, breakers, and grapple buckets. However, like all machinery, the auxiliary hydraulics on the 1845C can encounter issues over time. This article delves into the common problems, troubleshooting techniques, and maintenance tips for the auxiliary hydraulic system on the Case 1845C.
Understanding the Auxiliary Hydraulic System
The auxiliary hydraulics on the Case 1845C are crucial for powering a wide range of attachments. These systems are designed to provide additional hydraulic power, transferring fluid from the loader’s primary hydraulic system to the attachment. The auxiliary hydraulics on the 1845C can be configured for both low-flow and high-flow attachments, depending on the machine's specifications and the tasks at hand.
When operating attachments like a hydraulic hammer, post driver, or tree spade, the auxiliary hydraulics deliver the necessary power to perform these tasks. The 1845C can be equipped with an optional high-flow auxiliary hydraulic system, which allows for the use of more demanding attachments that require higher flow rates.
Common Issues with the Auxiliary Hydraulics on the Case 1845C
Despite the efficiency and power that auxiliary hydraulics offer, the Case 1845C may encounter some common issues that can affect its performance. These issues can often be traced back to hydraulic fluid problems, leaks, or component failure. Here are some of the most frequent problems:
If you encounter issues with the auxiliary hydraulics on the Case 1845C, you can perform a few troubleshooting steps to identify the problem.
To keep the auxiliary hydraulics in good working condition and avoid costly repairs, regular maintenance is key. Here are some important maintenance tips:
The Case 1845C auxiliary hydraulic system is a powerful feature that enhances the versatility of the skid steer loader. However, like any complex system, it is prone to certain issues such as weak flow, leaks, and solenoid valve failure. By understanding these common problems and following a proper maintenance routine, you can keep the auxiliary hydraulics in top shape for years of reliable service. Regular inspections, fluid changes, and addressing issues promptly can extend the life of your Case 1845C’s auxiliary system and ensure that it continues to perform efficiently in demanding applications.

Common Issues with the Auxiliary Hydraulics on the Case 1845C
Despite the efficiency and power that auxiliary hydraulics offer, the Case 1845C may encounter some common issues that can affect its performance. These issues can often be traced back to hydraulic fluid problems, leaks, or component failure. Here are some of the most frequent problems:
- Weak or Intermittent Flow
One of the most common complaints regarding the auxiliary hydraulics is weak or intermittent flow to attachments. This could be caused by several factors, such as a clogged filter, low hydraulic fluid levels, or issues with the hydraulic pump. A slow or fluctuating hydraulic flow can severely impact the performance of attachments, causing them to operate inefficiently or fail to work altogether.
- Hydraulic Fluid Leaks
Leaks are another frequent issue in hydraulic systems, including the auxiliary hydraulics of the 1845C. Leaks can occur at the hose connections, valve block, or fittings, leading to a loss of fluid pressure. This not only affects the machine’s overall performance but also risks running the system without sufficient hydraulic fluid, potentially causing damage to internal components.
- Faulty Solenoid Valves
The solenoid valve is responsible for controlling the flow of hydraulic fluid to the auxiliary circuits. If the solenoid fails, the loader will experience problems with activating the hydraulic functions. A faulty valve may not open or close properly, causing either no flow or excessive pressure, which could damage the attachment or the hydraulic system.
- Improperly Adjusted Pressure Relief Valve
A malfunctioning or improperly set pressure relief valve can prevent the hydraulic system from reaching the required pressure to operate attachments efficiently. If the relief valve is set too low, it could cause attachments to underperform. If it is set too high, it could over-pressurize the system, potentially leading to catastrophic failure.
If you encounter issues with the auxiliary hydraulics on the Case 1845C, you can perform a few troubleshooting steps to identify the problem.
- Check Hydraulic Fluid Levels and Quality
Always start by checking the hydraulic fluid levels. Low hydraulic fluid can cause the auxiliary system to underperform or fail to operate altogether. Additionally, ensure the fluid is clean and free from contaminants. If the fluid appears dirty, it’s essential to drain the system and replace the fluid with the recommended type and quantity.
- Inspect for Leaks
Visually inspect the hydraulic hoses, fittings, and connections for any signs of leaks. A drop in hydraulic pressure often leads to fluid leakage. If you find any leaks, replace the damaged hoses or fittings immediately. Using hydraulic-compatible sealant can help prevent minor leaks from worsening.
- Examine the Solenoid Valve
The solenoid valve controls the flow of fluid to the auxiliary circuits. To check if the valve is functioning correctly, test it for any signs of sticking or failure to open/close properly. If the valve is faulty, it will need to be repaired or replaced.
- Test the Pressure Relief Valve
Use a pressure gauge to check if the pressure relief valve is properly set. If the valve is malfunctioning, it may need to be calibrated or replaced. Make sure the relief valve is set to the recommended pressure settings to ensure the proper flow to attachments.
- Inspect the Hydraulic Pump
A weak or inconsistent flow may indicate an issue with the hydraulic pump. Check the pump’s condition and ensure it is delivering sufficient pressure to operate the auxiliary hydraulics effectively. If the pump is faulty, it will need to be serviced or replaced.
To keep the auxiliary hydraulics in good working condition and avoid costly repairs, regular maintenance is key. Here are some important maintenance tips:
- Regular Fluid Checks
It’s essential to check the hydraulic fluid level regularly. Make sure to top off the fluid if it’s low, and perform a complete fluid change every 1,000 hours or as recommended by the manufacturer.
- Keep the System Clean
Dirt and debris can enter the hydraulic system and cause blockages or damage to components. Clean the system thoroughly during maintenance, and inspect the filters regularly. Replace the filters when they become clogged or dirty.
- Lubricate Moving Parts
Ensure that all moving parts in the hydraulic system, such as cylinders, pumps, and valves, are well-lubricated. Use the appropriate lubricant to minimize friction and wear on these components.
- Check for Leaks
Regularly inspect the hoses, fittings, and seals for signs of leaks. Address any leaks immediately to prevent damage to the hydraulic system and maintain optimal performance.
- Store Attachments Properly
Attachments that use the auxiliary hydraulics should be stored in a clean, dry place when not in use. Ensure that hoses are properly coiled and that no debris is allowed to accumulate on the attachments.
The Case 1845C auxiliary hydraulic system is a powerful feature that enhances the versatility of the skid steer loader. However, like any complex system, it is prone to certain issues such as weak flow, leaks, and solenoid valve failure.
