The Case 1845C skid steer loader is a robust and reliable machine widely used in construction, landscaping, and agricultural operations. Known for its compact design, strong lifting capacity, and versatility, the 1845C model has been a popular choice for operators requiring maneuverability in tight spaces. However, like all heavy equipment, it is not immune to mechanical issues, one of which involves the curl control system. Understanding and troubleshooting curl control issues in the Case 1845C is vital to maintaining the machine’s performance and ensuring that the loader’s hydraulic functions work properly.
This article explores common problems associated with the curl control system, explains how the system operates, and provides solutions to address issues effectively.
Understanding the Curl Control System
The curl control system in a skid steer loader like the Case 1845C refers to the hydraulic mechanism responsible for controlling the bucket's curling action—either raising the bucket or lowering it. This system works in conjunction with the lift and tilt functions of the loader, which are controlled by hydraulic cylinders.
The curl control is activated by a joystick or lever system that communicates with the hydraulic valves to adjust the position of the bucket or attachment. In most machines like the 1845C, curl control is used for tasks such as scooping, dumping, and leveling materials. The hydraulic system delivers pressurized fluid to the bucket cylinders, enabling precise control of the bucket's curl and dump actions.
Common Curl Control Problems on the Case 1845C
When facing issues with curl control on the Case 1845C, it’s important to troubleshoot the problem methodically. Here are the steps operators can take to identify and resolve common issues:
To minimize the risk of encountering curl control problems on the Case 1845C, regular maintenance is key. Here are some preventive maintenance steps that operators can take to ensure the smooth operation of the curl control system:
The curl control system on the Case 1845C skid steer loader is a critical component for efficient operation, especially in tasks that involve lifting, scooping, or dumping materials. Issues such as slow response, uneven curling, and hydraulic lock-up can disrupt work and cause delays, but these problems can often be traced to issues with fluid levels, leaks, hydraulic components, or the control system itself. Regular maintenance and timely troubleshooting are key to keeping the system running smoothly.
By following the steps outlined above and ensuring the proper maintenance of the hydraulic system, operators can prevent common curl control issues and extend the life of their Case 1845C skid steer loader.

Common Curl Control Problems on the Case 1845C
- Slow or Unresponsive Curl Action
One of the most common issues that operators face with the curl control system is a slow or unresponsive bucket curl. This can make it difficult to scoop, dump, or level materials efficiently, hindering productivity.
Possible Causes:- Low hydraulic fluid levels.
- Air in the hydraulic system.
- Leaking hydraulic lines or cylinders.
- Faulty hydraulic pump or control valve.
- Low hydraulic fluid levels.
- Uneven Curling Action
Another issue that may arise is uneven curling action, where one side of the bucket moves faster or more forcefully than the other. This could result in difficulty controlling the bucket during critical tasks, such as loading or leveling.
Possible Causes:- Worn hydraulic cylinders or seals.
- Blocked or dirty hydraulic filters.
- Malfunctioning control valves that do not provide balanced pressure to both sides of the bucket.
- Worn hydraulic cylinders or seals.
- Curl Control Lock-Up
Some operators may experience complete lock-up of the curl control, meaning the bucket refuses to curl either up or down. This can lead to significant downtime and frustration for operators.
Possible Causes:- Complete hydraulic fluid loss.
- Failure of the control valve mechanism.
- Blockage in the hydraulic lines.
- Complete hydraulic fluid loss.
- Jerky or Erratic Bucket Movement
If the bucket moves erratically, either jerking back and forth or moving suddenly without smooth transitions, this indicates a problem with the flow of hydraulic fluid or the responsiveness of the control system.
Possible Causes:- Dirty or degraded hydraulic fluid.
- Faulty or sticky control valve.
- Damaged hydraulic hoses or fittings causing fluid leakage.
- Dirty or degraded hydraulic fluid.
When facing issues with curl control on the Case 1845C, it’s important to troubleshoot the problem methodically. Here are the steps operators can take to identify and resolve common issues:
- Check Hydraulic Fluid Levels
Low hydraulic fluid is a frequent cause of slow or unresponsive curl control. Always start by checking the hydraulic fluid reservoir. If the fluid level is low, top it off with the recommended type of fluid, and inspect the system for leaks. Ensure that the hydraulic fluid is clean, as contaminated fluid can also lead to performance issues.
- Inspect for Leaks
Leaking hydraulic lines, fittings, or cylinders can lead to a loss of hydraulic pressure, which affects the curl action. Carefully inspect all hydraulic hoses and connections for signs of wear, cracks, or leaks. If any leaks are found, replace the affected components promptly.
- Bleed the Hydraulic System
Air in the hydraulic system can result in poor or slow performance. If you suspect air contamination, "bleeding" the system can help eliminate trapped air and restore normal hydraulic flow. This process involves running the machine with the loader arms and bucket lifted and cycling the hydraulic controls to expel the air from the system.
- Check Control Valves and Hoses
A malfunctioning control valve may be the reason behind uneven curling or erratic movement. If you suspect a valve issue, the control valve may need to be cleaned, repaired, or replaced. Additionally, inspect hydraulic hoses for damage, abrasions, or blockages, as these can interfere with fluid flow.
- Examine the Hydraulic Pump
If the curl action is consistently slow or the bucket refuses to curl, a problem with the hydraulic pump could be the issue. A pump that is not producing enough pressure can prevent the hydraulic system from operating efficiently. Have the pump inspected and replaced if necessary.
- Replace Worn Cylinders or Seals
Worn hydraulic cylinders or damaged seals can lead to an uneven curl or loss of pressure. If the cylinders are leaking or the seals are worn, they will need to be replaced. A professional technician can assist with these repairs, as improper installation could lead to further issues.
To minimize the risk of encountering curl control problems on the Case 1845C, regular maintenance is key. Here are some preventive maintenance steps that operators can take to ensure the smooth operation of the curl control system:
- Frequent Hydraulic Fluid Checks
Regularly monitor the hydraulic fluid levels and condition. Ensure that the fluid is clean and within the proper range. Flushing the system periodically can help remove contaminants and improve the overall performance of the hydraulic system.
- Inspect Hydraulic Hoses and Fittings
Inspect hydraulic hoses, fittings, and connections regularly for signs of wear, cracks, or leaks. Replace any damaged hoses immediately to prevent fluid loss and maintain the system’s integrity.
- Clean Hydraulic Filters
Clogged hydraulic filters can restrict fluid flow, causing poor performance of the curl control. Clean or replace filters according to the manufacturer’s recommendations to ensure proper flow and prevent contamination.
- Regularly Cycle the Bucket
Periodically cycling the bucket and loader arms through their full range of motion helps keep the hydraulic system in good working order. This practice ensures that the hydraulic valves and cylinders are functioning smoothly and that no issues with movement arise.
- Lubrication of Moving Parts
Keep all moving parts, including the bucket pins and cylinders, properly lubricated to reduce wear and prevent stiffness in the hydraulic system.
