Bobcat 751 Issues and Troubleshooting Solutions - MikePhua - 07-04-2025
On Panswork, a user shared their experience with the Bobcat 751 skid steer encountering several issues, particularly with starting and power loss. The machine had difficulty starting, especially in colder weather, and even when it did start, the engine's performance was below expectations, leading to reduced efficiency. This sparked a broad discussion, with many users sharing their own experiences and solutions to help others diagnose and fix similar problems.
Common Issues and Symptoms
The most commonly reported problems with the Bobcat 751 included difficulty starting and power loss. Users noted that the machine struggled to start, particularly in cold weather. Even when it did start, the engine’s performance was far from ideal, with insufficient power output, which affected normal operation. Some users also mentioned that after starting, the machine would run unevenly and sometimes even stall.
Possible Causes of the Issue
Here are some of the potential causes discussed by users that could lead to these problems:
- Battery and Electrical System Failures
Many users believe that the difficulty starting the machine is related to insufficient battery voltage or electrical system faults. The Bobcat 751 may struggle to start if the battery is old or has been used for a long time, leading to inadequate starting voltage. Without sufficient current from the battery, the machine may either fail to start or fail to run properly once it starts.
- Fuel System Problems
Fuel supply issues are another common cause of engine starting problems. Some users found that a clogged fuel filter, faulty fuel pump, or malfunctioning fuel injectors could all affect engine startup and performance. Any issue in the fuel system can lead to unstable fuel delivery, impacting the engine's normal operation.
- Air Filter and Intake System Issues
A clogged air filter or a leaking intake system can cause insufficient airflow to the engine, affecting its combustion efficiency. Some users mentioned that when the air filter is dirty or blocked, the engine can’t get enough air, leading to difficulty starting and reduced power.
- Cold Starting Issues
Some users pointed out that the Bobcat 751 has difficulty starting in low temperatures, especially in colder climates. Cold starting problems are often linked to inadequate engine preheating or oil that is too thick, making it harder for the engine to start or leading to stalling.
Based on the discussion on Panswork, here are some of the effective solutions that users have shared:
- Check the Battery and Electrical System
Ensure that the battery has sufficient voltage and check the electrical connections for any loose or damaged wiring. Users recommended regular inspection of the battery and electrical system, especially before cold weather, to ensure enough starting current is available.
- Clean or Replace the Fuel Filter
Check and replace the fuel filter to ensure smooth fuel delivery. If issues with the fuel pump or injectors are found, they should be repaired or replaced to restore proper fuel system functionality.
- Replace the Air Filter
Regularly inspect the air filter to ensure it isn’t clogged with dust or debris. If the air filter is dirty, it should be replaced to maintain airflow and ensure the engine runs efficiently.
- Use Appropriate Oil for Cold Weather
For cold starting issues, users suggested using oil that is suitable for colder temperatures, as this reduces the oil’s viscosity, making it easier for the engine to start.
Difficulty starting and power loss in the Bobcat 751 is usually linked to issues with the battery, fuel system, air filter, or cold starting in low temperatures. The key to resolving these issues is regular inspection and maintenance of the battery, electrical system, fuel system, and air filter. Keeping these systems in good working order will help prevent these problems and ensure the machine can start and operate efficiently in various working conditions.
If you encounter similar problems, refer to the experiences of other users on Panswork and take the necessary steps, or seek professional technical support, to ensure the machine operates smoothly and lasts longer.
