The 2011 Case SR220 is a highly efficient skid steer loader, known for its excellent performance in construction, landscaping, and agricultural applications. Like all heavy equipment, regular maintenance is key to keeping it running smoothly. One of the most common maintenance tasks for operators and mechanics alike is replacing the drive belts. The SR220, with its hydraulic-driven system, relies on a set of belts that power crucial components, including the engine and hydraulics.
In this article, we will explore how to replace the belts on the 2011 Case SR220, identify common issues that may arise, and provide maintenance tips for prolonging the life of the machine. This guide will help owners and operators keep their skid steer running efficiently, while minimizing downtime.
Understanding the Role of Belts in the SR220
The belts in the Case SR220 serve to transmit power from the engine to various components. These include the alternator, hydraulic pumps, and cooling system. When these belts wear out, they can cause a variety of issues, such as:
As with all components on heavy equipment, belts will wear out over time and require replacement. Here are the common signs that it’s time to replace the belts on your SR220:
Replacing the belts on a 2011 Case SR220 is a task that requires some mechanical knowledge, but it’s not too complex for most owners to handle. Here's a step-by-step guide on how to do it.
1. Prepare the Equipment
Before you begin, ensure that the skid steer is safely parked on a flat surface. Engage the parking brake and turn off the engine. Always wear protective gloves and eye protection to avoid injuries from sharp parts or debris.
2. Disconnect the Battery
It’s always a good practice to disconnect the machine’s battery to avoid any electrical issues or shocks while working around the engine compartment.
3. Remove the Access Panels
On the SR220, you’ll need to remove the engine access panels. Use a wrench or screwdriver to unscrew and remove the bolts holding the panels in place. This will give you clear access to the belts and pulleys.
4. Inspect the Belts and Pulleys
Before replacing the belts, take a moment to inspect the pulleys and other related components. If the pulleys are worn, misaligned, or damaged, replacing the belts will only provide a temporary fix. Ensure that all pulleys are in good condition and rotate freely.
5. Loosen the Tensioner
The SR220’s drive belts are typically tensioned by a spring-loaded tensioner. Use a wrench or ratchet to loosen the tensioner, allowing slack in the belt. Once slack is created, you should be able to remove the old belt.
6. Remove the Old Belt
Carefully slide the worn or damaged belt off the pulleys. Be mindful of the routing of the belt as it passes around various components. If you have trouble removing it, check for any obstructions or tight spots.
7. Install the New Belt
Position the new belt according to the routing diagram. Ensure the belt fits snugly into all the pulleys. Make sure the teeth or grooves on the belt are aligned with the grooves on the pulleys to ensure proper engagement.
8. Tighten the Tensioner
Once the new belt is installed, tighten the tensioner to ensure the belt has the correct amount of tension. The tension should be tight enough to prevent slippage, but not so tight that it causes undue strain on the system.
9. Test the System
After installing the new belt, rotate the engine by hand to check for any abnormal movement. Start the engine and check for proper operation of the hydraulic system, alternator, and cooling system. Listen for any unusual sounds and check for smooth operation.
10. Reassemble and Test Drive
Once everything is in place and functioning correctly, replace the engine access panels and reconnect the battery. Perform a test drive of the machine to ensure everything is working smoothly.
Common Issues and Troubleshooting
While replacing the belts on your Case SR220 is a straightforward job, some issues may arise. Here are a few common troubleshooting tips:
To get the most out of your belts and avoid frequent replacements, consider the following maintenance tips:
Replacing the belts on a 2011 Case SR220 skid steer is a manageable task for most operators. By following the proper steps and ensuring you’re using the correct parts, you can maintain optimal performance from your machine. Regular maintenance and timely belt replacements will help ensure the longevity and reliability of your skid steer. If in doubt, consult the machine’s service manual or a professional mechanic to guide you through the process.

Understanding the Role of Belts in the SR220
The belts in the Case SR220 serve to transmit power from the engine to various components. These include the alternator, hydraulic pumps, and cooling system. When these belts wear out, they can cause a variety of issues, such as:
- Slippage: When a belt becomes loose or worn, it may slip, reducing the efficiency of the system.
- Loss of Power: A broken or worn-out belt can prevent the alternator, hydraulic system, or cooling fan from functioning properly.
- Excessive Wear: Belts that are not replaced on time can lead to increased wear on other engine components, potentially leading to more serious mechanical issues.
As with all components on heavy equipment, belts will wear out over time and require replacement. Here are the common signs that it’s time to replace the belts on your SR220:
- Squealing Noises: A high-pitched squeal from the engine compartment often indicates a worn or loose belt. This sound is typically caused by the belt slipping over the pulleys.
- Reduced Hydraulic Power: If the machine's hydraulics start to lose power or respond slowly, the drive belt connected to the hydraulic pump may be worn or loose.
- Engine Overheating: If the cooling fan is not spinning as efficiently as it should, it can cause the engine to overheat. A worn or broken belt could be the culprit.
- Visible Cracks or Fraying: Inspect the belts for any visible signs of damage such as cracks, fraying, or missing teeth. These are all indicators that the belt needs to be replaced.
- Excessive Belt Wear: If the belt shows signs of excessive wear (like uneven or excessive glazing), it’s time to swap it out for a new one.

Common Issues and Troubleshooting
While replacing the belts on your Case SR220 is a straightforward job, some issues may arise. Here are a few common troubleshooting tips:
- Belts Slipping: If you notice that the new belts are slipping, they may be too loose or improperly tensioned. Recheck the tension and adjust as needed.
- Overheating: If the engine continues to overheat after replacing the belt, check that the cooling fan is operating properly. A faulty fan motor or a clogged radiator could be the issue.
- Hydraulic Problems: If hydraulic performance is still lacking after a belt replacement, inspect the hydraulic pump and fluid levels. A failed pump or low fluid can mimic the symptoms of a belt issue.
To get the most out of your belts and avoid frequent replacements, consider the following maintenance tips:
- Regular Inspections: Inspect belts regularly for signs of wear, cracks, or fraying. Catching small issues early can prevent the need for more frequent replacements.
- Proper Tension: Always maintain the proper tension on your belts. Too loose and they’ll slip; too tight and they’ll wear out faster.
- Avoid Overloading: Overloading the skid steer can put excessive strain on the belts and other components. Stick to the recommended load limits to keep the belts in good condition.
- Clean the Engine: A clean engine compartment reduces the risk of debris getting into the belt system. Use compressed air to clean the area around the belts and pulleys regularly.
