- Inspect the wiring harnesses for damage or wear, and replace any broken or frayed wires.
- Test the fuses and replace any that have blown.
- Inspect the battery terminals for corrosion or loose connections. Clean and tighten them as needed.
- Symptoms: Electrical problems can lead to issues like the machine not starting, erratic behavior of lights, or malfunctions of certain components such as the hydraulic controls or engine management system.
- Tracks and Undercarriage Wear
- Symptoms: A worn-out undercarriage or tracks can cause the machine to operate inefficiently. The machine might experience uneven movement, lack of traction, or excessive vibration.
- Causes:
- Normal wear and tear from prolonged use, especially on rough terrain.
- Improper track tension leading to excessive wear.
- Damage to the undercarriage components, such as rollers, idlers, or sprockets.
- Normal wear and tear from prolonged use, especially on rough terrain.
- Solutions:
- Check the track tension regularly and adjust it to the manufacturer’s specifications. Over-tightening or under-tightening the tracks can lead to rapid wear.
- Inspect the tracks for cracks, cuts, or missing teeth and replace them as needed.
- Inspect the undercarriage components like rollers and sprockets for wear and replace any worn-out parts.
- Regularly clean the undercarriage to prevent debris from causing damage.
- Check the track tension regularly and adjust it to the manufacturer’s specifications. Over-tightening or under-tightening the tracks can lead to rapid wear.
- Symptoms: A worn-out undercarriage or tracks can cause the machine to operate inefficiently. The machine might experience uneven movement, lack of traction, or excessive vibration.
- Overheating
- Symptoms: The engine temperature gauge may show that the Bobcat T190 is running hotter than normal, which could indicate an overheating issue. The machine may also experience power loss, or you may hear unusual engine sounds due to excessive heat.
- Causes:
- Clogged radiator or cooling fins preventing airflow.
- Low coolant levels or a faulty thermostat.
