2001 Bobcat 753 G Skid Steer Float Feature and Bucket Positioning Button Issue

[MikePhua]

In the 2001 Bobcat 753 G skid steer loader, issues with the float feature and bucket positioning button may arise, leading to improper operation. The float feature allows the bucket to float freely when in contact with the ground, providing smoother and more precise operation. The bucket positioning button is used to adjust the bucket’s angle and position for more accurate tasks. Faults in either of these functions can affect the machine's performance, so timely troubleshooting is essential.
Common Causes

1. Float Feature Switch Malfunction
   The float feature switch may be damaged or malfunction, preventing the float feature from engaging. This is often due to mechanical failure of the switch itself or poor electrical connections.
   
2. Hydraulic System Issues
   Both the float feature and bucket positioning button rely on the hydraulic system to function properly. Low hydraulic pressure, contaminated oil, or leaks in the system may lead to malfunction of these functions.
   
3. Electrical Wiring Issues
   Electrical wiring for the float feature and bucket positioning button may be damaged, worn, or have poor connections, leading to signal transmission failures and preventing the system from working as intended.
   
4. Button Failure
   The bucket positioning button itself may fail due to wear, internal circuit issues, or prolonged use, rendering it unresponsive.
   
5. Control Valve Malfunction
   The hydraulic control valves that manage the float feature and bucket positioning may become stuck or malfunction, preventing the proper adjustment of the bucket angle or engaging the float feature.
   

Troubleshooting Steps

1. Check the Float Feature Switch
   Inspect the float feature switch for damage or looseness. Use diagnostic tools to test if the switch is functioning properly, and ensure that all electrical connections are secure. If the switch is faulty, it may need to be replaced.
   
2. Inspect the Hydraulic System
   Check the hydraulic fluid level and quality, and ensure there are no leaks in the pump or hoses. Low pressure or contaminated fluid can affect the float feature and bucket positioning functionality.
   
3. Check the Electrical Wiring
   Inspect the electrical wiring for the float feature and bucket positioning button. Look for loose connections, wear, or damage. Use a multimeter to test the circuit and ensure proper signal transmission.
   
4. Inspect the Button Functionality
   Check if the bucket positioning button is working as expected. If it does not respond, it may have an internal electrical issue or mechanical failure. In this case, the button will need to be replaced.
   
5. Examine the Hydraulic Control Valves
   Check the hydraulic control valves associated with the float feature and bucket positioning. If the valves are stuck or damaged, it could prevent proper hydraulic flow, affecting the function of both features.
   

Preventive Measures

1. Regular Hydraulic System Maintenance
   Regularly check the quality and level of hydraulic fluid. Replace the fluid and filters as necessary to keep the hydraulic system in good condition and prevent contamination.
   
2. Periodic Electrical System Inspection
   Inspect the electrical wiring and switches regularly to ensure connections are secure and there is no damage. Preventative maintenance on electrical systems can avoid malfunctions.
   
3. Maintain Buttons and Control Valves
   Periodically check the bucket positioning button and hydraulic control valves for wear. Replace any damaged components promptly to avoid failure during operation.
   
4. Avoid Overuse of the Float Feature
   Minimize prolonged or excessive use of the float feature to reduce wear on the system and extend its lifespan.
   

Conclusion
The float feature and bucket positioning button issues in the 2001 Bobcat 753 G skid steer loader are commonly caused by hydraulic system issues, electrical wiring problems, button failure, or control valve malfunctions. Regular maintenance of the hydraulic system, electrical wiring, and key components can prevent these issues from occurring. Timely troubleshooting and repairs will ensure the loader operates smoothly and efficiently.
