Your T190 can develop problems over time. Understanding these common issues helps owners diagnose faults early, reduce downtime, and extend the machine’s service life.
Bobcat T190 Problems
1. Hydraulic System Problems
The hydraulic system is one of the most critical parts of the Bobcat T190 and also one of the most common sources of trouble. Operators may notice slow lift arms, weak bucket performance, jerky movement, or complete hydraulic failure.
These problems are often caused by low hydraulic fluid levels, contaminated oil, clogged hydraulic filters, or worn hydraulic pumps. Damaged hoses and loose fittings can also cause pressure loss and inconsistent operation. In high-hour machines, internal pump wear or faulty relief valves may reduce system efficiency.
Regularly checking hydraulic fluid levels, changing filters on schedule, and inspecting hoses for leaks or cracks can prevent most hydraulic issues. If problems persist, a hydraulic pressure test may be necessary to identify failing components.
2. Engine Performance Issues
Engine-related problems are another common concern for Bobcat T190 owners. Typical symptoms include hard starting, rough idling, power loss under load, excessive smoke, or engine knocking.
Dirty air or fuel filters are often the root cause, restricting airflow or fuel delivery. Fuel system issues, such as worn injectors or low fuel pressure, can also reduce engine performance. Older machines may experience turbocharger wear, leading to reduced power and poor throttle response. Low oil pressure or poor lubrication can result in engine noise and long-term damage if not addressed promptly.
Routine maintenance, including filter replacement, oil changes, and fuel system inspections, is essential. Monitoring engine temperature and oil pressure helps detect problems before they become severe.

3. Electrical and Control System Faults
Electrical problems in the Bobcat T190 can be frustrating because they often appear suddenly and intermittently. Common issues include failure to start, control panel shutdowns, warning lights appearing unexpectedly, or loss of joystick control.
These problems are typically caused by corroded wiring, loose connections, failing safety switches, or faulty relays. Moisture intrusion and vibration over time can damage electrical connectors and wiring harnesses, leading to unreliable operation.
Inspecting electrical connections, cleaning terminals, and securing loose wiring can resolve many electrical faults. If problems persist, diagnosing safety interlock circuits and control modules may be required.
4. Drive System and Final Drive Problems
The drive system, including the hydrostatic transmission and final drives, is another area where wear can occur, especially on machines with high operating hours. Operators may experience weak travel power, uneven movement, unusual noises, or complete loss of drive on one side.
These issues often stem from worn drive motors, clogged case drain filters, internal seal failure, or contaminated hydraulic oil. Metal particles in the oil are a warning sign of internal wear and should be addressed immediately.
Regular oil changes, monitoring case drain filters, and inspecting drive components can significantly extend the life of the final drives. Ignoring early symptoms can lead to costly repairs or complete drive replacement.

5. Cooling and Overheating Issues
Overheating can affect both engine and hydraulic performance in the Bobcat T190. Symptoms include rising engine temperature, reduced power, and automatic shutdowns to prevent damage.
Common causes include clogged radiators, dirty cooling fans, low coolant levels, or prolonged operation under heavy load. Debris buildup is especially common when working in dusty or muddy environments.
Keeping the cooling system clean, checking coolant levels, and ensuring proper airflow through the radiator can prevent overheating and improve overall reliability.
6. Track, Undercarriage, and Wear Issues
The undercarriage and tracks of the Bobcat T190 experience constant stress, particularly on rough terrain. Uneven track wear, loss of traction, or excessive vibration can affect machine performance and stability.
Improper track tension, worn rollers, damaged sprockets, or misalignment are common causes. Neglecting undercarriage maintenance can lead to accelerated wear and higher replacement costs.
Regular inspection of tracks, rollers, and tension settings helps maintain smooth operation and reduces downtime.

Preventive Maintenance Tips
Many Bobcat T190 problems can be avoided with proper care and routine inspections. Key preventive measures include:
- Checking hydraulic, engine, and coolant fluid levels daily
- Replacing filters and fluids at recommended service intervals
- Inspecting hoses, belts, and wiring for damage
- Cleaning radiators and cooling components regularly
- Monitoring the drive system performance and oil condition
Proactive maintenance not only reduces repair costs but also improves safety and machine efficiency.

FAQs
How to tell if a Bobcat hydraulic pump is bad?
A bad hydraulic pump on a Bobcat usually shows clear performance symptoms. Common signs include slow or weak lift and tilt functions, jerky or uneven hydraulic movement, excessive whining or grinding noises from the pump area, and overheating hydraulic oil.
You may also notice loss of hydraulic pressure under load, frequent relief valve activation, or metal particles in the hydraulic filter or oil. If fluid levels and filters are correct but performance continues to drop, a pressure test is often the best way to confirm pump failure.
How much can a Bobcat T190 lift?
The Bobcat T190 has a rated operating capacity of approximately 1,900 pounds. This rating represents 50 percent of the machine’s tipping load and is designed to ensure safe and stable operation. Actual lifting performance can vary depending on attachment type, load position, track condition, and operating surface. Lifting beyond the rated capacity can lead to instability and increased wear on hydraulic and structural components.
Where is the traction lock solenoid on a Bobcat T190?
The traction lock solenoid on a Bobcat T190 is typically located within the hydraulic control valve assembly, near the drive control components. It is usually mounted under the operator’s cab or behind access panels close to the hydrostatic system.
Access often requires tilting the cab forward and removing protective covers. The solenoid controls drive engagement and is linked to safety interlock systems that prevent unintended machine movement.
What are common Bobcat T190 problems?
Common Bobcat T190 problems include hydraulic system failures such as weak lift power or leaks, engine performance issues like hard starting and power loss, electrical faults involving wiring or safety switches, and drive system wear affecting the hydrostatic transmission or final drives. Overheating, undercarriage wear, and track issues are also frequently reported, especially on high-hour machines. Most of these problems can be minimized through regular maintenance, proper operation, and early diagnosis.
Final Thoughts
The Bobcat T190 remains a dependable and capable compact track loader when properly maintained. While it is prone to certain hydraulic, engine, electrical, and drive system issues, most problems develop gradually and provide warning signs before major failure occurs.
By understanding common Bobcat T190 problems and addressing them early, owners can keep their machines productive, reliable, and cost-effective for many years.
