Replacing the contaminated fuel with high-quality fuel should resolve the issue.įuel pump failure is a more serious fuel system problem. Contamination occurs from debris, old fuel, or poor fuel storage conditions. Replacing the filter should fix the issue.įuel contamination can also cause operational issues in the excavator. A clogged fuel filter limits the amount of fuel reaching the engine, which can strain the excavator. These filters clog due to the accumulation of dirt on the filter. One of the fuel system problems you’ll encounter is clogged fuel filters. These fuel problems can cause issues with the engine, such as problems starting the engine or fuel starvation. Fuel System Problemsīobcat 331 fuel problems can affect one or more fuel system components, including filters, fuel pumps, and fuel lines. Debris accumulation is a common source of issues in the system as it creates obstructions. Keeping your excavator clean can prevent most bobcat 331 problems in the hydraulic system.

Replace the damaged cylinder to restore its function. When the cylinder fails, the excavator will likely not work. Hydraulic problems in the Bobcat 331 can also appear as cylinder failure due to wear or damage. Identifying and fixing leaks should be a priority to prevent worse issues from developing. Leaks in the hydraulic system occur due to corrosion or physical damage to the hoses. The more the hydraulic fluid leaks, the higher the chances of dealing with additional problems like overheating the hydraulic system. Hydraulic leaks, for example, can cause contamination of the engine and other surrounding components, reducing the excavator’s efficiency. 7 Problems With Bobcat 331 Excavators are Inevitable Hydraulic Problemsīobcat 331 hydraulic problems can cause poor operation of the excavator.
