Bobcat 773G Fuel Pickup Problem: Diagnosis and Solutions
#1
On Panswork, users discussed issues with the Bobcat 773G, where the machine experiences fuel pickup problems, resulting in poor engine performance or failure to start. This issue is often linked to faults in the fuel system, which could be caused by a malfunctioning fuel pump, clogged fuel filter, or damaged fuel lines. Below is an overview of common problems and their solutions.
Common Problems:
  1. Fuel Pickup Issues
Many Bobcat 773G users have reported problems where the engine doesn't get sufficient fuel, either during operation or upon startup. This is usually related to a failure in some component of the fuel system.
Solution:
  • First, check the fuel pump to ensure it is working properly. Over time, fuel pumps can fail due to wear or contamination.
  • Check the fuel filter for clogs. If the fuel filter is blocked, fuel won't flow to the engine, resulting in poor performance or failure to start. Replacing the fuel filter is often necessary.
  • Inspect the fuel lines for cracks, leaks, or damage. Any compromised fuel line can lead to insufficient fuel pickup, affecting engine operation.
  1. Fuel System Leaks
Any leaks within the fuel system can impact the proper flow of fuel, causing the engine to stall unexpectedly or fail to start altogether.
Solution:
  • Conduct a thorough inspection of the fuel system, especially the fuel lines and fittings, to check for leaks.
  • Make sure that all fuel line connections are secure, and that no leaks are present at the junctions.
  1. Fuel Contamination
Using poor-quality or contaminated fuel can also affect the Bobcat 773G’s fuel supply, leading to engine issues.
Solution:
  • Check the quality of the fuel being used. If the fuel is contaminated, it may need to be replaced, and the fuel system should be cleaned.
  • Clean the fuel system and check for any debris or sediment blocking the lines or filter.
Preventive Measures:
  • Regular Fuel System Checks: Regularly inspect the fuel pump, fuel filter, and fuel lines to ensure there are no leaks, clogs, or contamination.
  • Use High-Quality Fuel: Always use clean, high-quality fuel to prevent contamination that could damage the fuel system.
  • Regular Maintenance and Cleaning: Perform routine cleaning and maintenance of the fuel system to keep all components in good working order.
Conclusion:
Fuel pickup issues in the Bobcat 773G are usually linked to problems with the fuel pump, fuel filter, fuel lines, or contaminated fuel. Regular inspection and maintenance of the fuel system, particularly the fuel pump and filter, can help prevent these issues. If the problem is complex or persists, it’s recommended to consult a professional technician for diagnosis and repair to ensure the equipment operates smoothly over time.
