Bobcat 863 Deutz Factory Remanufactured Engine Losing Power and Smoking - MikePhua - 07-04-2025
A user reported an issue with their Bobcat 863, which has a Deutz factory remanufactured engine. The engine began to lose power and emit smoke, leading to confusion since the engine had been professionally remanufactured and should have been in good working order.
Problem Description
After some time of use, the Bobcat 863 engine started showing signs of reduced power, along with white or blue smoke coming from the exhaust. The user checked various components, including the air filter, fuel system, and coolant temperature, but the issue persisted and seemed to worsen over time.
Possible Causes
From the forum discussion, several possible causes for the problem were suggested:
- Fuel System Issues: Some users recommended checking the fuel pump and injectors to ensure they are working properly. A malfunctioning fuel system can lead to either too much or too little fuel being delivered to the engine, causing a loss of power and smoke.
- Air Intake Issues: A clogged air filter or a leak in the intake system may prevent enough air from reaching the engine, leading to incomplete combustion and the generation of white or blue smoke.
- Turbocharger Failure: Some users pointed out that a damaged turbocharger could be responsible for the smoke, especially if the turbo is leaking oil. This can lead to poor combustion and significant smoke production.
- Cooling System Problems: Overheating or malfunctioning cooling systems can cause the engine to run at excessively high temperatures, affecting combustion efficiency and causing smoke along with power loss.
Several users shared their experiences on the forum, including cleaning the air filter and replacing the fuel pump and injectors, but the issue was not fully resolved. Other users advised re-checking basic engine components, especially the turbocharger and cooling system, to identify the potential source of the fault.
Conclusion and Recommendations
To avoid further damage, it is recommended that the owner first checks and maintains the fuel system and air intake system, ensuring proper airflow and fuel delivery. It’s also a good idea to inspect the turbocharger and cooling system for leaks or overheating. If the problem persists and involves internal engine components, seeking help from a professional mechanic is advised.
