The Bobcat 610 is a versatile skid-steer loader widely used in construction and agricultural applications. However, some users encounter fuel pump issues, resulting in engine startup failures or unstable operation. This article summarizes common problems and provides solutions.
Overview of the Problem
Many users report that the Bobcat 610's engine cannot get adequate fuel supply during startup or that the fuel pump fails to work properly. This typically manifests as difficulty starting the engine or intermittent stalling during operation. The most common cause is a failure within the fuel pump, which prevents the fuel pressure from reaching the necessary level.
Common Fuel Pump Failures
Fuel pump issues on the Bobcat 610 are often related to electrical problems, fuel filter clogging, fuel line leaks, and poor fuel quality. Regular inspection and maintenance of these components can significantly extend the life of the equipment and reduce unnecessary repairs or downtime. For problems that cannot be solved independently, it’s advisable to contact professional service personnel.

Common Fuel Pump Failures
- Fuel Pump Damage
The most common failure is an issue with the electrical components of the fuel pump, preventing it from operating correctly. This can be due to a malfunctioning motor inside the pump or loose wiring leading to insufficient power supply.
- Clogged Fuel Filter
A clogged fuel filter can also reduce the flow of fuel, causing problems with engine startup and operation. When debris or dirt accumulates in the filter, it restricts fuel flow to the engine.
- Fuel Line Leaks
Cracks or loose connections in the fuel lines can prevent the fuel from flowing into the pump, leading to starting issues.
- Poor Fuel Quality
Using low-quality fuel or fuel containing water can negatively affect the fuel pump's operation. Over time, poor fuel quality can accelerate wear and tear on the fuel system.
- Check the Power Supply
First, inspect the fuel pump’s electrical connections to ensure they are secure and the battery voltage is sufficient. If the power is normal but the fuel pump still doesn’t work, the pump’s motor may be damaged.
- Check the Fuel Filter
Clean or replace the fuel filter to ensure proper fuel flow. A clogged filter can lead to poor fuel supply, which may affect machine performance.
- Inspect the Fuel Lines
Thoroughly inspect the fuel lines for leaks, particularly at the connections. If any leaks are found, repair or replace the damaged sections to ensure a steady fuel supply.
- Test the Fuel Quality
Make sure the fuel being used is clean and meets the required specifications. If you suspect poor fuel quality, use a fuel filter or replace the fuel with a cleaner one for testing.
- Replace the Fuel Pump
If the fuel pump is found to be damaged, the best solution is to replace it with an OEM (Original Equipment Manufacturer) part suitable for the Bobcat 610 model.
- Clean or Replace the Fuel Filter
Regularly clean or replace the fuel filter to maintain the fuel system. In harsh operating environments, it’s crucial to check the filter often to prevent unnecessary issues.
- Repair Fuel Line Leaks
Inspect the fuel lines carefully, and if any loose connections or cracks are found, replace or repair them immediately to ensure proper fuel delivery.
- Use High-Quality Fuel
Choose high-quality fuel to extend the life of the fuel pump and prevent damage caused by water or impurities. Using a fuel filter to clean the fuel can also prevent system contamination.
Fuel pump issues on the Bobcat 610 are often related to electrical problems, fuel filter clogging, fuel line leaks, and poor fuel quality. Regular inspection and maintenance of these components can significantly extend the life of the equipment and reduce unnecessary repairs or downtime.
