Bobcat 773 Low Power Issue Troubleshooting: Fuel-Related Problems - MikePhua - 07-04-2025
The Bobcat 773 skid steer experiencing low power issues is often linked to fuel system failures. These problems can result in insufficient engine power, affecting the machine’s performance. Below is a breakdown of common fuel-related causes for low power in the Bobcat 773 and troubleshooting solutions.
Problem Description
Users have reported that their Bobcat 773 skid steer experiences low power, where the engine starts normally but struggles to provide adequate power, especially under heavy load. Upon inspection, the issue appears to be related to the fuel supply system, possibly involving the fuel pump, filter, or other fuel components.
Common Causes and Solutions
- Check the Fuel Filter
A clogged fuel filter is one of the most common causes of low power. When the filter becomes clogged with dirt or debris, it restricts the flow of fuel to the engine, causing poor performance. Inspect the fuel filter and replace any that are clogged or damaged. This is the first step in restoring normal power output.
- Fuel Pump Failure
If the fuel pump is malfunctioning or damaged, it may fail to properly deliver fuel to the engine, resulting in low power. Check if the fuel pump is operating correctly and ensure it is providing a steady fuel supply to the engine. If the pump is faulty, it will need to be replaced or repaired.
- Inspect Fuel Lines
Fuel line leaks or blockages can also lead to insufficient fuel delivery. Inspect all fuel lines to ensure there are no leaks, cracks, or clogs. If any issues are found, replace or clean the fuel lines to ensure proper fuel flow to the engine.
- Check Fuel Quality
Poor fuel quality, contamination, or the presence of water can lead to engine instability and low power. If you suspect fuel issues, replace the fuel with high-quality, clean fuel. Also, check the fuel tank for water or sediment, and clean it if necessary.
- Inspect Fuel Filter and Supply System
Some Bobcat 773 users have reported issues with the fuel supply system’s filters becoming worn or damaged, leading to restricted fuel flow. Regularly inspect the fuel supply system and filters, and replace them when needed to ensure smooth fuel delivery to the engine.
Low power in the Bobcat 773 skid steer is often fuel-related. By checking the fuel filter, fuel pump, fuel lines, and fuel quality, most issues can be resolved. If the problem persists after addressing these areas, it is recommended to contact Panswork’s professional repair service for further inspection and repairs.
