Bobcat T190 Troubleshooting and Common Issues

[MikePhua]

The Bobcat T190 is a versatile and reliable skid-steer loader commonly used in construction, landscaping, and agricultural applications. However, like any piece of heavy machinery, it can encounter various issues during operation. This article addresses some of the common problems with the Bobcat T190 and provides troubleshooting steps to resolve them.
Common Issues with Bobcat T190:

1. Hydraulic Problems:
   Hydraulic issues are common in skid-steer loaders, including the Bobcat T190. These problems may include low hydraulic pressure, weak lift or tilt functions, or complete failure of the hydraulic system. If the machine is not responding properly, it is essential to inspect the hydraulic fluid levels, filters, and hoses for leaks or blockages.
   Troubleshooting:
   • Check hydraulic fluid levels regularly and top off if necessary.
     
   • Inspect hoses and fittings for leaks.
     
   • Replace or clean the hydraulic filter if clogged.
     
   • Test the hydraulic pump for proper operation.
     
2. Fuel Delivery Issues:
   Problems with fuel delivery can also affect the T190's performance. These may include fuel not reaching the engine, causing starting issues or loss of power. Fuel filters can become clogged, or the fuel lines can develop cracks, leading to fuel delivery problems.
   Troubleshooting:
   • Inspect the fuel system, including the tank, fuel lines, and filters.
     
   • Replace any clogged or damaged fuel filters.
     
   • Ensure there are no blockages in the fuel lines.
     
3. Starting Problems:
   Starting issues are common in older Bobcat T190 models, especially if the battery is weak or the glow plugs are malfunctioning. If the engine cranks but does not start, the problem could be related to the fuel system, glow plugs, or electrical components.
   Troubleshooting:
   • Check the battery voltage and replace it if necessary.
     
   • Inspect the glow plugs and replace any faulty ones.
     
   • Test the starter motor and solenoid for proper function.
     
4. Electrical System Failures:
   The electrical system in the Bobcat T190 is responsible for powering various components, including the lights, controls, and the engine starter. If the electrical system is malfunctioning, the machine may experience intermittent power loss or total failure.
   Troubleshooting:
   • Inspect the wiring for corrosion or loose connections.
     
   • Test the alternator and charging system.
     
   • Check the fuses and relays for damage and replace them if needed.
     
5. Transmission and Drive System:
   The drive system on the Bobcat T190 can develop issues, such as slipping or jerking, if there is low fluid or if the transmission is damaged. It is crucial to ensure that the drive system is properly lubricated and that the transmission fluid levels are correct.
   Troubleshooting:
   • Check the transmission fluid level and add fluid as needed.
     
   • Inspect the drive belts for wear or damage.
     
   • Test the transmission for smooth shifting and operation.
     

General Maintenance Tips:

1. Regular Fluid Checks:
   Consistently check hydraulic fluid, engine oil, and transmission fluid levels. Maintaining the correct fluid levels helps prevent many common issues and keeps the machine running efficiently.
   
2. Proper Filter Maintenance:
   Regularly change the hydraulic and fuel filters to prevent blockages and ensure proper flow throughout the system.
   
3. Inspect for Leaks:
   Frequently inspect hoses, lines, and seals for signs of leaks. This will help identify any small issues before they become major problems.
   
4. Grease Moving Parts:
   Lubricate all moving parts, such as joints and pivots, to reduce wear and tear and prolong the life of the machine.
   

Conclusion:
The Bobcat T190 is a durable machine, but like any piece of heavy equipment, it requires regular maintenance and occasional troubleshooting to keep it in optimal working condition. By addressing common issues like hydraulic problems, fuel delivery issues, and electrical failures, you can ensure that your Bobcat T190 continues to perform reliably and efficiently. If the problems persist after troubleshooting, it is advisable to contact a professional technician for further assistance.
