Common Symptoms of Power Loss in Bobcat T190
When your Bobcat T190 begins to lose power, run rough, or produce excessive smoke, it’s often an indication that something is amiss under the hood. These symptoms are typically signs of underlying engine or fuel system problems, which could range from minor issues to more significant mechanical failures. Let’s take a closer look at the symptoms and potential causes:
- Loss of Power:
One of the first signs of trouble in the T190 is a noticeable loss of power when the machine is working hard. If the loader struggles to lift loads or operate at full capacity, this could be indicative of issues with the fuel system, air intake, or engine components.
- Rough Running Engine:
If the engine is running roughly, it could be due to irregular fuel delivery, clogged filters, or issues with the engine's internal components like the injectors or the fuel pump.
- Excessive Smoke:
The T190 might emit more smoke than usual, particularly under load. Smoke can vary in color, with black smoke generally indicating an excess of fuel, while white or blue smoke can signal an oil or coolant issue. This is a key diagnostic indicator.
There are several factors that could be contributing to the issues you're experiencing with the T190. Below are the most common causes and their associated symptoms:
- Fuel System Issues:
- Clogged Fuel Filter: A clogged or dirty fuel filter can restrict fuel flow to the engine, leading to poor combustion, rough engine performance, and power loss. This is a common issue when operating in dusty or dirty environments.
- Fuel Pump Problems: If the fuel pump is failing, it can result in inadequate fuel delivery, causing the engine to lose power and run roughly.
- Fuel Contamination: Contaminated fuel can cause significant engine problems, including rough running and power loss. Water or dirt in the fuel can lead to poor combustion and engine misfires.
- Solution: Replace the fuel filter and check the fuel lines for blockages. If fuel contamination is suspected, flush the fuel system and replace the fuel pump if needed.
- Clogged Fuel Filter: A clogged or dirty fuel filter can restrict fuel flow to the engine, leading to poor combustion, rough engine performance, and power loss. This is a common issue when operating in dusty or dirty environments.
- Air Intake Problems:
- Clogged Air Filter: A clogged air filter can prevent proper air intake, which is essential for the engine’s combustion process. Without a steady supply of clean air, the engine will struggle to perform efficiently, leading to power loss and rough running.
- Air Restriction: Other factors, such as a blocked intake hose or exhaust system, can also reduce the airflow to the engine, causing it to work harder and produce excess smoke.
- Solution: Inspect the air filter and replace it if necessary. Ensure there are no blockages in the air intake system or exhaust.
- Clogged Air Filter: A clogged air filter can prevent proper air intake, which is essential for the engine’s combustion process. Without a steady supply of clean air, the engine will struggle to perform efficiently, leading to power loss and rough running.
- Engine Overheating:
- Cooling System Problems: If the engine is overheating, it can cause a decrease in performance and a rough running engine. Common causes of overheating include low coolant levels, a malfunctioning radiator, or a damaged thermostat.
- Solution: Check the coolant levels and ensure the radiator and cooling fan are functioning properly. If overheating persists, consider flushing the radiator or replacing the thermostat.
- Cooling System Problems: If the engine is overheating, it can cause a decrease in performance and a rough running engine. Common causes of overheating include low coolant levels, a malfunctioning radiator, or a damaged thermostat.
- Dirty or Worn-out Injectors:
- Injector Failure: Faulty or dirty fuel injectors can lead to poor fuel atomization and incomplete combustion, which can result in rough engine performance, power loss, and smoke.
- Solution: Clean or replace the fuel injectors as needed. A professional mechanic may need to test the injectors for proper operation.
- Injector Failure: Faulty or dirty fuel injectors can lead to poor fuel atomization and incomplete combustion, which can result in rough engine performance, power loss, and smoke.
- Turbocharger Issues (if equipped):
- Turbocharger Failure: If your Bobcat T190 is equipped with a turbocharger, a failure in the turbo can lead to a drop in power and the engine running rough. This could be caused by issues like worn bearings or a damaged seal.
- Solution: Inspect the turbocharger for damage and listen for unusual noises. If the turbo is failing, it will likely need to be replaced or rebuilt.
- Turbocharger Failure: If your Bobcat T190 is equipped with a turbocharger, a failure in the turbo can lead to a drop in power and the engine running rough. This could be caused by issues like worn bearings or a damaged seal.
If you encounter these symptoms with your T190, follow this step-by-step approach to troubleshoot and fix the issue:
- Check the Fuel System:
- Start by inspecting the fuel filter. A clogged filter is a common cause of power loss. Replace it if it appears dirty or damaged.
- Next, check for any signs of fuel contamination, such as water in the fuel tank. If you suspect contamination, drain the fuel tank, flush the system, and replace the fuel filter.
- If the fuel system appears to be in good condition but the power loss continues, have the fuel pump tested or replaced by a professional.
- Start by inspecting the fuel filter. A clogged filter is a common cause of power loss. Replace it if it appears dirty or damaged.
- Inspect the Air Intake and Filters:
- Check the air filter for dirt, debris, or damage. A dirty or clogged air filter can significantly reduce engine performance. If it’s dirty, replace it with a new one.
- Look over the entire air intake system for any signs of blockage. Ensure that the intake hose is free of cracks and that the exhaust system is not obstructed.
- Check the air filter for dirt, debris, or damage. A dirty or clogged air filter can significantly reduce engine performance. If it’s dirty, replace it with a new one.
- Test the Engine Temperature:
- Overheating is another common cause of rough running. Make sure the engine is not running too hot. Check the radiator, coolant levels, and thermostat. If necessary, flush the radiator and replace any worn components.

To prevent issues like power loss, rough running, and excessive smoking in the future, follow these maintenance tips:
- Regularly Replace Filters: Keep both the air and fuel filters clean and replace them on schedule. Dirty filters are often the cause of engine performance issues.
- Use High-Quality Fuel: Always use clean, high-quality fuel to avoid contamination and damage to the fuel system. In areas with poor fuel quality, consider using fuel additives.
- Monitor Fluid Levels: Regularly check and top off the coolant, engine oil, and hydraulic fluids to ensure optimal engine performance and prevent overheating.
- Inspect the Turbocharger: If your Bobcat T190 is turbocharged, inspect the turbocharger for wear and tear. A properly functioning turbo will ensure the engine operates efficiently under load.
- Keep the Loader Clean: Regularly clean the machine to prevent dirt and debris from entering the engine, fuel system, or air intake.
