Another common complaint is the engine losing power or difficulties starting the machine. This issue could be due to several factors, including problems with the fuel system, electrical components, or the engine itself.
Possible Causes:
Regularly replacing fuel filters and inspecting the fuel injectors can help prevent fuel system issues. If the engine is hard to start, check the battery and alternator for any electrical issues. A diagnostic test can help pinpoint the cause of power loss, and in many cases, replacing damaged parts can restore engine performance.
3. Steering Problems:
Some users have reported issues with the steering mechanism, such as unresponsive or stiff controls. The Bobcat 843 uses a hydraulic steering system, and problems here may indicate low fluid levels, worn-out steering components, or issues with the steering linkage.
Symptoms of Steering Problems:
Check the hydraulic fluid levels and refill if necessary. If the problem persists, inspect the steering components for wear. The steering linkage should be checked for any looseness or damage, and replacing faulty parts should restore proper steering function.
4. Cooling System Failures:
Like many heavy equipment models, the Bobcat 843 is susceptible to cooling system failures. Overheating can occur if the radiator is clogged or the coolant is not at optimal levels.
Signs of Cooling Issues:
Make sure to check the radiator for any blockages or debris that could impede airflow. Regularly monitor the coolant level and top it off as needed. If the radiator or cooling system components are damaged, they may need to be replaced to avoid engine damage.
Preventative Maintenance for the Bobcat 843
To minimize the risk of issues and ensure the longevity of the Bobcat 843, regular maintenance is essential. Below are some preventative steps that can help keep your skid steer in top shape:
The Bobcat 843 skid steer loader is a powerful and reliable piece of machinery for a variety of construction and landscaping tasks. However, like all used equipment, it requires regular maintenance and careful attention to ensure it continues to operate at peak performance. By understanding the common issues and taking preventative steps, you can extend the life of the machine and keep it running efficiently, ensuring you get the most out of your investment.
Whether you’re considering purchasing a used Bobcat 843 or already own one, being proactive about its care will help avoid costly repairs and downtime in the future. Regular inspections, proper maintenance, and prompt repairs when needed are key to keeping this versatile loader in excellent working condition.
