The Bobcat 873 skid steer loader is a powerful and versatile machine used in a variety of applications, from construction to landscaping. However, like all heavy equipment, it requires attention to detail in maintenance and troubleshooting. If you're a new owner, here’s a guide to help you deal with common issues and keep your Bobcat 873 running smoothly.
Common Problems with the Bobcat 873
The Bobcat 873 is a reliable and versatile machine that can handle a wide range of tasks. However, like any piece of equipment, it requires regular maintenance and attention to keep running at its best. By addressing common issues such as hydraulic system failures, electrical problems, and engine overheating, and following regular maintenance schedules, you can extend the life of your Bobcat 873 and ensure it serves you well for years to come.
Common Problems with the Bobcat 873
- Hydraulic System Issues:
One of the most common issues new owners face with the Bobcat 873 is problems with the hydraulic system. Hydraulic leaks, slow hydraulic response, or erratic movements of the loader arms can indicate issues with seals, hoses, or the hydraulic pump. Always check for any visible leaks and monitor the hydraulic fluid level. If the fluid is low, top it off and inspect the system for any damage.
- Starting Problems:
Another frequent issue is difficulty starting the machine. This can be caused by a weak battery, faulty solenoid, or worn starter motor. Make sure the battery is in good condition, with clean terminals and a full charge. If the battery is good but the machine still struggles to start, inspect the solenoid and wiring for any signs of wear or corrosion.
- Electrical Failures:
Electrical issues, such as malfunctioning lights or non-functional controls, are common in older Bobcat 873 models. Problems can stem from blown fuses, corroded connections, or faulty relays. To troubleshoot, check all electrical connections and ensure the fuses are in working order. A multimeter can help test the voltage and identify the source of electrical failure.
- Overheating Engine:
If the engine begins to overheat, check the cooling system. Issues like a clogged radiator, low coolant levels, or a malfunctioning thermostat can cause overheating. Clean the radiator regularly to remove dirt and debris, and always ensure that the coolant is at the proper level. If the machine continues to overheat, further inspection of the cooling system may be required.
- Regular Fluid Checks and Changes:
Regular maintenance is key to keeping the Bobcat 873 operating efficiently. Make sure to change the engine oil and filter as recommended by the manufacturer. Additionally, check the hydraulic fluid levels and replace the hydraulic filter regularly to maintain optimal performance.
- Inspect and Maintain the Tires:
Inspect the tires for wear, punctures, or other damage. The Bobcat 873’s tires are essential for providing traction, especially in rough or uneven terrain. If the tires are excessively worn or damaged, replacing them will improve the machine’s stability and performance.
- Grease All Moving Parts:
Greasing the machine regularly will prevent excessive wear on moving parts such as the boom, bucket arms, and hydraulic cylinders. Use the appropriate grease and apply it to all recommended grease points to keep the loader operating smoothly and avoid costly repairs.
- Check the Tracks:
For models equipped with tracks, regularly inspect them for tension and wear. Proper track tension is essential to ensure smooth operation and avoid unnecessary wear on the drive system. If the tracks are loose or damaged, replacing them or adjusting their tension may be necessary.
- Listen to Unusual Noises: Pay close attention to any strange noises, such as grinding or squealing, which could indicate a mechanical issue.
- Test All Controls: Operate the machine in different settings to ensure all controls and movements are functioning properly.
- Keep the Machine Clean: Dirt and debris can build up in various parts of the machine, causing it to overheat or malfunction. Cleaning the Bobcat 873 after each use will help maintain its longevity.
The Bobcat 873 is a reliable and versatile machine that can handle a wide range of tasks. However, like any piece of equipment, it requires regular maintenance and attention to keep running at its best. By addressing common issues such as hydraulic system failures, electrical problems, and engine overheating, and following regular maintenance schedules, you can extend the life of your Bobcat 873 and ensure it serves you well for years to come.
