Introduction
The Bobcat 753, a compact skid steer loader, is known for its versatility and power, handling a range of tasks from construction to landscaping. However, like all heavy machinery, it can experience mechanical issues over time. One common complaint from operators is the jerking motion while driving, which can significantly affect the machine’s performance and safety. This issue, if left unresolved, may lead to further damage and more costly repairs. In this article, we will explore the causes behind jerking movements in the Bobcat 753, how to diagnose the issue, and provide some useful tips on troubleshooting.
What Causes Drive Jerking in Bobcat 753?
Drive jerking refers to the sudden, erratic movements of the machine while it’s being driven, especially when trying to move smoothly. For the Bobcat 753, several factors can contribute to this problem. Some of the most common causes include:
To effectively diagnose the jerking issue in your Bobcat 753, follow a step-by-step approach:
Regular maintenance is key to preventing jerking and other performance issues with the Bobcat 753. Here are some tips to keep your machine running smoothly:
In one case, a Bobcat 753 owner experienced significant jerking in the drive system, particularly when operating on uneven ground. After conducting a thorough inspection, the operator found that the hydraulic fluid was low, and the filter was clogged with dirt and debris. Once the hydraulic fluid was replaced and the filter cleaned, the jerking stopped. This case illustrates how simple maintenance, like fluid checks and cleaning, can go a long way in solving issues that seem complicated at first.
Conclusion
Jerking in the Bobcat 753 drive system is a common issue that can stem from various factors, including hydraulic problems, transmission issues, drive motor failures, or damaged wheels. Diagnosing the problem involves inspecting the hydraulic system, transmission, drive motor, wheels, and electrical components. By following regular maintenance practices and addressing issues promptly, operators can prevent jerking and ensure the machine performs optimally for years to come.
If you continue to experience difficulties after performing these checks, it may be time to consult a professional mechanic or technician to ensure a thorough and accurate diagnosis. Keeping your Bobcat 753 in top shape will not only improve its performance but also extend its lifespan, ultimately saving you money on costly repairs and downtime.

What Causes Drive Jerking in Bobcat 753?
Drive jerking refers to the sudden, erratic movements of the machine while it’s being driven, especially when trying to move smoothly. For the Bobcat 753, several factors can contribute to this problem. Some of the most common causes include:
- Hydraulic System Issues
The Bobcat 753 relies heavily on its hydraulic system for movement, including driving the wheels. If the hydraulic system is malfunctioning, it can cause jerking or stuttering movements. Potential issues could include low hydraulic fluid, clogged filters, or problems with the hydraulic pump or motor.
- Transmission Problems
The transmission is crucial for the smooth transfer of power from the engine to the drive wheels. Any issues in the transmission system—such as worn-out gears or low fluid levels—can lead to jerky movements. Transmission problems might also arise from improperly adjusted or damaged drive belts or couplings.
- Drive Motor Failures
The Bobcat 753 uses a hydraulic drive motor that controls the wheels' movement. If the drive motor is malfunctioning, it may cause inconsistent power delivery to the wheels, leading to jerky, uneven movement. This issue could stem from a damaged motor, loose connections, or a failing pump.
- Wheel or Axle Issues
Sometimes, the issue may be related to the wheels themselves. Worn-out or damaged wheels and axles can contribute to jerking during operation. If the wheel bearings are not properly lubricated or if the wheels are unbalanced, they may cause the machine to jerk.
- Electrical Problems
Electrical issues, such as faulty wiring or poor sensor connections, can lead to erratic behavior in the Bobcat 753. Malfunctions in the drive system's control circuit can result in unpredictable movements, especially during acceleration or turning.
To effectively diagnose the jerking issue in your Bobcat 753, follow a step-by-step approach:
- Check Hydraulic Fluid Levels
Begin by inspecting the hydraulic fluid levels. Low fluid or dirty fluid can cause the hydraulic system to perform poorly. If the fluid is low, top it up and check for any leaks in the system. Clean or replace the hydraulic filter if necessary.
- Inspect the Transmission
Next, check the transmission fluid levels. Low or contaminated fluid can cause issues with gear shifting and power transfer. If the fluid looks dark or dirty, it may be time to replace it. Additionally, inspect the drive belts and couplings for wear or damage.
- Examine the Drive Motor
Inspect the hydraulic drive motor for signs of wear or leaks. If you suspect the motor is the issue, test the motor's performance and check for unusual noises or irregular power delivery. A damaged motor will likely need to be repaired or replaced.
- Look for Signs of Wheel or Axle Damage
Inspect the wheels for any signs of damage, such as cracks or excessive wear. Check the wheel bearings for proper lubrication and ensure they rotate smoothly. If the axles are bent or the wheels are misaligned, it could lead to jerky movements.
- Check the Electrical System
Inspect the electrical components, including wiring and sensors, for any loose or damaged connections. If there is an issue with the electrical system, it may require professional diagnostic equipment to pinpoint the exact problem.
Regular maintenance is key to preventing jerking and other performance issues with the Bobcat 753. Here are some tips to keep your machine running smoothly:
- Follow a Regular Maintenance Schedule
Always adhere to the manufacturer’s recommended maintenance schedule. Regular fluid checks, filter replacements, and system inspections can help catch problems early before they become major issues.
- Keep the Hydraulic System Clean
Clean hydraulic filters and ensure the system remains free of contaminants. This will help maintain optimal performance and prevent issues such as jerking caused by poor fluid circulation.
- Monitor Wheel and Axle Health
Regularly check the wheels for any signs of wear and tear. Replace any damaged wheels or bearings as needed. Keeping the wheels properly aligned and balanced is essential for smooth operation.
- Check Electrical Connections
Ensure all electrical components are working correctly and that connections are secure. A loose or damaged wire can lead to erratic behavior, including jerking movements.
- Store the Machine Properly
Proper storage of your Bobcat 753 when it’s not in use can also contribute to its longevity. Avoid leaving it in extreme weather conditions or letting it sit for extended periods without proper care.
