The CAT 247B skid steer is one of Caterpillar’s renowned machines designed for versatility in various construction and material handling tasks. Known for its compact size, powerful performance, and advanced features, this skid steer continues to be a popular choice for operators working in tight spaces or areas requiring maneuverability. However, like all heavy machinery, the 247B can experience technical issues that may impact its performance.
This article will examine common issues encountered with the CAT 247B, possible solutions, and preventative maintenance tips to ensure the continued smooth operation of the machine.
Overview of the CAT 247B Skid Steer
Caterpillar introduced the 247B skid steer as part of their multi-terrain loader (MTL) lineup. Its combination of excellent maneuverability, strong lifting capacity, and advanced hydraulic system makes it ideal for a variety of applications, including construction, landscaping, and agricultural work. Key specifications of the 247B include:
Common Problems and Troubleshooting Tips
Although the CAT 247B is designed to handle demanding tasks, like any heavy equipment, it can experience technical issues over time. Below are some of the most common problems and possible solutions.
1. Hydraulic System Failures
The hydraulic system is the heart of the 247B’s functionality, powering its loader arm, bucket, and other attachments. A malfunction in this system can lead to slow or unresponsive movements, affecting productivity.
Engine-related problems, such as difficulty starting, are common in machines that have seen heavy use or have not been maintained properly.
Electrical issues are another common problem faced by operators, particularly with components like lights, sensors, or control systems.
Since the 247B is a multi-terrain loader with rubber tracks, undercarriage problems can occur, especially in demanding working environments. Track issues can severely impact the machine’s performance and stability.
To avoid issues and extend the lifespan of your CAT 247B, follow these essential maintenance practices:
1. Regular Fluid Checks and Changes
Ensure that all fluid levels—engine oil, hydraulic fluid, and coolant—are checked and maintained regularly. Regular fluid changes help prevent issues like overheating, engine wear, and poor hydraulic performance. Always use the recommended fluids and replace filters as part of routine maintenance.
2. Track and Undercarriage Inspection
Inspect the tracks and undercarriage frequently, especially if operating in harsh conditions. Clean the tracks after each use and check for any signs of wear. Proper track tension is crucial to avoid excessive wear or slippage.
3. Check the Battery and Electrical System
Perform routine inspections of the battery, alternator, and wiring. Corrosion on terminals can hinder performance, so clean and maintain them regularly. Checking the battery voltage will help you avoid starting issues.
4. Regular Air and Fuel Filter Replacements
Replace air and fuel filters according to the maintenance schedule. Clogged filters can reduce engine performance and fuel efficiency. Regular filter replacements will also help maintain the longevity of the engine.
5. Grease and Lubricate Moving Parts
The 247B has many moving components that require regular lubrication, such as pins, bushings, and joints. Apply grease as recommended by the manufacturer to reduce friction and prevent premature wear.
Conclusion
The CAT 247B skid steer is a durable and reliable piece of machinery, ideal for a wide range of applications. By staying on top of maintenance and troubleshooting common issues, operators can ensure that their 247B runs efficiently and reliably for years. Regular checks on the hydraulic system, engine components, and undercarriage are essential for optimal performance. Following these guidelines and performing preventive maintenance will not only help extend the life of the equipment but also improve its overall productivity on the job site.

Common Problems and Troubleshooting Tips
Although the CAT 247B is designed to handle demanding tasks, like any heavy equipment, it can experience technical issues over time. Below are some of the most common problems and possible solutions.
1. Hydraulic System Failures
The hydraulic system is the heart of the 247B’s functionality, powering its loader arm, bucket, and other attachments. A malfunction in this system can lead to slow or unresponsive movements, affecting productivity.
- Symptoms: Slow bucket movements, unresponsive arm, or uneven lifting capabilities.
- Possible Causes:
- Low hydraulic fluid levels.
- Contaminated hydraulic fluid or dirty filters.
- Leaking hydraulic hoses or fittings.
- Faulty hydraulic pump or valve.
- Low hydraulic fluid levels.
- Solution:
- Check the hydraulic fluid levels and top up if necessary. Ensure that the fluid is clean and at the correct level.
- Replace dirty or clogged hydraulic filters and clean the system if contamination is present.
- Inspect hoses and fittings for leaks or damage. Replace any compromised parts.
- Test the hydraulic pump and valves to ensure they are functioning correctly. Replace any faulty components.
- Check the hydraulic fluid levels and top up if necessary. Ensure that the fluid is clean and at the correct level.
Engine-related problems, such as difficulty starting, are common in machines that have seen heavy use or have not been maintained properly.
- Symptoms: Engine cranks but does not start, or starting is slow.
- Possible Causes:
- Weak or discharged battery.
- Clogged fuel filter or faulty fuel injectors.
- Problems with the starter motor or alternator.
- Dirty or damaged air filter.
- Weak or discharged battery.
- Solution:
- Check the battery voltage and replace it if it’s weak or showing signs of wear.
- Replace the fuel filter and inspect fuel injectors for clogging. Clean or replace them as necessary.
- Test the starter motor and alternator to ensure they are functioning properly.
- Clean or replace the air filter to ensure the engine is getting the necessary airflow.
- Check the battery voltage and replace it if it’s weak or showing signs of wear.
Electrical issues are another common problem faced by operators, particularly with components like lights, sensors, or control systems.
- Symptoms: Electrical components not working, such as lights, sensors, or control panel displays.
- Possible Causes:
- Blown fuses or damaged wiring.
- Faulty relays or switches.
- Corroded electrical connections.
- Blown fuses or damaged wiring.
- Solution:
- Inspect fuses and replace any that are blown.
- Check all wiring for signs of wear or damage, and repair or replace as needed.
- Inspect relays and switches for proper operation. Replace any defective electrical components.
- Inspect fuses and replace any that are blown.
Since the 247B is a multi-terrain loader with rubber tracks, undercarriage problems can occur, especially in demanding working environments. Track issues can severely impact the machine’s performance and stability.
- Symptoms: Tracks slipping off, excessive wear, or irregular movement.
- Possible Causes:
- Incorrect track tension.
- Damaged or worn-out rollers and idlers.
- Foreign objects lodged in the tracks.
- Incorrect track tension.
- Solution:
- Check track tension and adjust if necessary. Over-tightened tracks can cause excessive wear, while under-tightened tracks may slip.
- Inspect rollers, idlers, and sprockets for signs of wear or damage. Replace any worn-out parts.
- Clean debris from the tracks and undercarriage regularly to prevent foreign objects from obstructing movement.
- Check track tension and adjust if necessary. Over-tightened tracks can cause excessive wear, while under-tightened tracks may slip.
