Common Issues with the Bobcat 700 Series
While the Bobcat 700 Series skid steers are generally well-regarded for their reliability, like any piece of heavy equipment, they can experience certain problems over time. Below are some of the more common issues that may arise with the Bobcat 700 series, along with their possible causes and solutions.
1. Hydraulic System Problems
The hydraulic system is critical for the operation of the skid steer, and any failure in this system can cause significant issues with the machine's performance.
Symptoms:

• Slow or jerky movement of the loader arms and boom.
  
• Difficulty lifting or moving heavy loads.
  
• Attachments not operating properly.
  

Possible Causes:

• Low hydraulic fluid levels: A common issue caused by leaks, wear, or improper maintenance.
  
• Clogged hydraulic filters: Over time, filters can become blocked by dirt, debris, and contaminants, reducing the flow and pressure of hydraulic fluid.
  
• Damaged hydraulic hoses or seals: Cracked hoses or worn seals can cause leaks, which reduce the effectiveness of the hydraulic system.
  

Solutions:

• Check and top up hydraulic fluid regularly to ensure the correct levels.
  
• Clean or replace hydraulic filters as per the maintenance schedule.
  
• Inspect hoses and seals for wear or damage and replace them as necessary.
  

2. Electrical Failures
Electrical issues in the Bobcat 700 Series can range from minor inconveniences, such as lights not working, to major malfunctions that prevent the machine from starting or operating properly.
Symptoms:

• The machine won't start.
  
• Electrical components, such as lights, gauges, or the horn, don't function.
  
• Battery quickly drains or doesn't hold charge.
  

Possible Causes:

• Dead or weak battery: Over time, the battery can lose its ability to hold a charge, particularly if it is old or the machine isn't used regularly.
  
• Faulty alternator: A malfunctioning alternator may fail to charge the battery properly, leading to electrical problems.
  
• Loose or corroded electrical connections: Poor connections can interrupt the flow of electricity to critical components.
  

Solutions:

• Test the battery, and replace it if it's no longer holding a charge.
  
• Check the alternator for proper functionality, and replace it if necessary.
  
• Inspect all electrical connections for looseness or corrosion, and clean or tighten as needed.
  

3. Engine Performance Issues
If the engine isn't running smoothly, it can severely affect the machine's performance. Engine issues can range from rough idling to total failure.
Symptoms:

• The engine stalls or doesn’t start.
  
• Rough idling or loss of power.
  
• Excessive smoke from the exhaust.
  

Possible Causes:

• Clogged air filter: A dirty air filter restricts airflow to the engine, causing it to perform poorly.
  
• Fuel delivery issues: Problems with the fuel injectors or fuel pump can result in poor engine performance.
  
• Low oil levels: Insufficient lubrication can lead to excessive engine wear and overheating.
  

Solutions:

• Replace the air filter regularly to ensure smooth engine operation.
  
• Inspect and clean fuel injectors, and replace the fuel pump if it’s faulty.
  
• Check the oil levels frequently, and perform oil changes at the recommended intervals to prevent engine damage.
  

4. Track or Wheel Wear
Skid steer loaders with tracks or wheels may experience wear and tear over time, especially if used in rough terrain or for extended periods.
Symptoms:

• Uneven or noisy movement when driving.
  
• Reduced traction or slipping.
  
• Vibration or instability during operation.
  

Possible Causes:

• Improper track tension: Too tight or too loose tracks can lead to premature wear and poor performance.
  
• Overloading the machine: Carrying too much weight can put excessive strain on the tracks or wheels, causing damage.
  
• Harsh operating conditions: Working on rough, rocky, or uneven terrain can cause the tracks or wheels to wear out faster.
  

Solutions:

• Regularly check and adjust track tension as needed according to the manufacturer’s specifications.
  
• Avoid exceeding the recommended load limits to reduce strain on the tracks or wheels.
  
• Inspect tracks or wheels regularly for signs of excessive wear, and replace them as necessary.
  

5. Overheating Problems
Overheating can be a significant issue for any heavy equipment, including the Bobcat 700 Series. If not addressed, it can lead to engine damage or failure.
Symptoms:

• The temperature gauge reading is high.
  
• The engine stalls or shuts down.
  
• The engine compartment or radiator becomes excessively hot.
  

Possible Causes:

• Low coolant levels: Without sufficient coolant, the engine will overheat.
  
• Dirty or clogged radiator: A dirty or clogged radiator cannot dissipate heat properly.
  
• Faulty thermostat: A malfunctioning thermostat may prevent the cooling system from working as intended.
  

Solutions:

• Regularly check coolant levels and top up as needed.
  
• Inspect the radiator for blockages or leaks, and clean it regularly.
  
• Test the thermostat and replace it if it’s faulty.
