Lowering the Loader on a Case 1845C Skid Steer: Troubleshooting and Tips

[MikePhua]

The Case 1845C is a popular skid steer loader known for its durability and versatility on construction sites, farms, and other heavy-duty work environments. However, like any machine, it can encounter operational issues. One common problem is the inability to lower the loader arms, which can cause disruptions and slow down operations. Understanding how to troubleshoot and solve this issue is vital for keeping your machine running smoothly. This article will break down the potential causes of this problem and offer solutions to help you efficiently lower the loader arms on your Case 1845C skid steer.
Common Reasons for Loader Arms Not Lowering
Several factors can prevent the loader arms from lowering properly, and each requires a unique approach for diagnosis and repair. Here are some of the most common causes:

1. Hydraulic System Issues
   The most likely reason for the loader arms not lowering is a malfunction within the hydraulic system. The Case 1845C relies heavily on hydraulics to lift and lower the arms, so any disruption in this system can result in the loader not functioning as expected. Key hydraulic components to check include:
   • Hydraulic Fluid Level: Low fluid levels can affect the performance of the hydraulic system. If the fluid level is too low, the arms may not lower correctly. Regularly check the hydraulic fluid to ensure it's within the proper range.
     
   • Hydraulic Hoses: Leaking or damaged hoses can cause pressure loss, which will prevent the loader arms from operating properly. Inspect hoses for visible damage, leaks, or wear.
     
   • Hydraulic Pump: The hydraulic pump is responsible for creating the pressure needed to operate the loader arms. If the pump is malfunctioning, the arms will struggle to move. Symptoms of a faulty pump include sluggish or erratic movement of the arms.
     
2. Control Valve Malfunction
   The control valve is responsible for directing hydraulic fluid to the proper cylinder to raise or lower the loader arms. A stuck or malfunctioning valve may prevent the fluid from flowing correctly. If the valve becomes clogged with debris or worn over time, it can block the flow of hydraulic fluid to the lift cylinders, preventing the arms from lowering.
   
3. Lift Cylinder Problems
   If the lift cylinders are damaged, worn, or leaking, they may fail to respond properly. The Case 1845C has two lift cylinders that need to function in unison to raise and lower the loader arms. If either cylinder is compromised, the machine may not operate correctly.
   
4. Electrical Issues
   Though the 1845C primarily relies on hydraulics, there may be electrical components that affect the movement of the loader arms. A malfunction in the electrical system, such as a blown fuse or a faulty solenoid, can impact the operation of the hydraulic system. Electrical components that could cause problems include:
   • Solenoids: These control the flow of hydraulic fluid. If one is malfunctioning, it can prevent the loader arms from lowering.
     
   • Wiring or Fuses: Damaged wiring or blown fuses can also cause issues with the hydraulic system, especially if the electrical connections aren't properly engaging the hydraulic components.
     
5. Valve Bank or Joystick Problems
   The valve bank and joystick controls play a key role in directing hydraulic fluid. If the valve bank is malfunctioning or if the joystick is unresponsive, it may fail to signal the hydraulic system to lower the loader arms. Common issues include worn-out components, loose connections, or dirt and debris clogging the system.
   

Troubleshooting Steps to Lower the Loader
If you're encountering issues with lowering the loader arms on your Case 1845C, here’s a step-by-step approach to help you diagnose and fix the problem:

1. Check the Hydraulic Fluid Level
   • First, ensure the hydraulic fluid is at the correct level. If it's low, add the appropriate fluid for your skid steer model. If the fluid is dark or has an unusual smell, consider changing the fluid, as it could be contaminated or burned.
     
2. Inspect the Hydraulic System
   • Check all hydraulic hoses for visible signs of wear or damage. Look for leaks, kinks, or any abrasions that might be causing a loss of pressure.
     
   • Examine the hydraulic pump and ensure it is functioning properly. If the pump is failing, it may need to be replaced.
     
3. Test the Control Valve
   • Test the control valve by trying to operate the loader arms from the joystick. If the valve is not responding or feels sluggish, it could be clogged or worn. Cleaning or replacing the valve may be necessary.
     
4. Examine the Lift Cylinders
   • Inspect the lift cylinders for any visible signs of damage or leakage. If you find any damage, the cylinders may need to be resealed or replaced. Worn-out seals can lead to hydraulic fluid leakage, reducing the efficiency of the lift mechanism.
     
5. Check for Electrical Issues
   • Inspect the solenoids, wiring, and fuses related to the hydraulic system. Test the solenoids to ensure they are working correctly. Replace any blown fuses or faulty wiring as needed.
     
6. Test the Joystick and Valve Bank
   • If the hydraulic system appears to be functioning properly but the loader arms still won’t lower, the issue might be with the joystick or the valve bank. Test the joystick to see if it’s responding to input. If it’s not, the joystick or valve bank might need to be repaired or replaced.
     

Preventive Maintenance to Avoid Future Issues
Regular maintenance can prevent many common issues that affect the loader arms on your Case 1845C. Here are a few tips to keep your machine in top condition:

1. Regular Fluid Checks: Always check the hydraulic fluid levels before use and ensure the fluid is clean and free from contaminants. Regular fluid changes are essential for maintaining the performance of the hydraulic system.
   
2. Routine Inspections: Inspect the hydraulic hoses, lift cylinders, and control valves for wear or damage. Early detection of issues can prevent costly repairs and downtime.
   
3. Keep the Electrical System in Good Shape: Ensure the electrical components, such as fuses, solenoids, and wiring, are in good working order. Regularly check these components to avoid electrical failures that could impact the hydraulic system.
   
4. Lubrication: Keep all moving parts properly lubricated to reduce friction and wear. This will extend the lifespan of components like the joystick, control valve, and lift cylinders.
   

Conclusion
The Case 1845C is a highly reliable skid steer loader, but like any complex machinery, it can experience issues that prevent the loader arms from lowering properly. Hydraulic problems, control valve malfunctions, lift cylinder issues, electrical failures, and joystick problems are some of the common causes of this issue. By following a step-by-step troubleshooting approach, operators can quickly identify the source of the problem and take corrective action.
Regular maintenance, fluid checks, and timely repairs are essential for keeping the Case 1845C operating smoothly. By staying on top of these tasks, operators can avoid downtime and ensure that their machine performs optimally for years to come.
