How to Remove the Air Filter Housing on a Bobcat L190 Skid Steer
#1
The Bobcat L190 is a highly versatile skid steer loader used in various construction, landscaping, and agricultural applications. One of the essential components for maintaining engine efficiency and performance is the air filter system, which prevents dirt and debris from entering the engine. Over time, maintenance tasks like replacing the air filter become necessary, and to access the filter, you'll need to remove the air filter housing.
In this article, we will guide you through the process of safely and effectively removing the air filter housing on the Bobcat L190, ensuring that you can perform this routine maintenance task without hassle.
Why Remove the Air Filter Housing?
The air filter housing is a critical component of the air intake system on the Bobcat L190. The primary purpose of the air filter is to clean the incoming air that feeds the engine. A clogged or dirty filter can cause reduced engine performance, higher fuel consumption, and even potential engine damage due to the accumulation of debris in the combustion chamber.
Here are some reasons why you might need to remove the air filter housing:
  • Replacing the Air Filter: If the air filter is clogged or dirty, it needs to be replaced. This is one of the most common maintenance tasks to keep the engine running smoothly.
  • Cleaning the Housing: Over time, dust and debris can accumulate within the housing, affecting airflow and the overall engine performance.
  • Troubleshooting Airflow Issues: If you're experiencing poor engine performance, reduced power, or excessive smoke, it may be caused by an air intake issue, such as a blocked filter housing.
Tools and Materials Needed
Before you begin the process of removing the air filter housing, make sure you have the necessary tools and materials:
  • Wrench or socket set
  • Ratchet driver
  • Screwdrivers (flathead and Phillips)
  • Replacement air filter (if you're planning to replace it)
  • Cleaning supplies (rags, brush, or compressed air)
Step-by-Step Guide to Remove the Air Filter Housing
Removing the air filter housing on the Bobcat L190 is a relatively simple procedure, but it requires care to avoid damaging any components. Follow the steps below for a smooth process:
Step 1: Turn Off the Engine and Disconnect the Battery
For safety, always start by turning off the engine and disconnecting the battery. This will prevent any accidental electrical shorts or startups while you're working on the equipment.
  • Important Tip: Make sure the skid steer is on a flat surface, and the engine has cooled down before starting the procedure.
Step 2: Locate the Air Filter Housing
The air filter housing on the Bobcat L190 is typically located near the engine’s air intake, which can be accessed from the engine compartment. It is a rectangular or cylindrical casing designed to house the air filter securely.
  • Helpful Hint: In some cases, the housing may be located behind the front grill or near the side of the engine compartment. If you're unsure of its location, refer to the owner's manual or consult an experienced mechanic.
Step 3: Remove the Housing Fasteners
The air filter housing is held in place by screws or bolts, typically located around the perimeter of the housing. Using the appropriate wrench or screwdriver, begin removing these fasteners.
  • Tip: Keep track of the screws and bolts by placing them in a container or laying them out on a clean surface, as they can be easy to misplace.
Step 4: Disconnect Any Hoses or Ducts
If there are any hoses, ducts, or air intake tubes connected to the air filter housing, carefully disconnect them by loosening the clamps or unscrewing the fasteners. Take care not to damage the hoses, as they are crucial for the air intake system.
  • Common Issue: In some models, there may be an air intake tube that is tightly attached to the housing. If this is the case, gently wiggle it loose, ensuring that no parts are bent or broken in the process.
Step 5: Remove the Air Filter Housing
Once all the fasteners have been removed and the hoses disconnected, carefully pull the air filter housing out of place. It may be a bit tight, so a gentle twist or pull might be required to dislodge it from its mounting.
  • Important Reminder: Make sure to support the housing properly while removing it to prevent any damage to the surrounding components.
Step 6: Inspect and Clean the Housing
With the air filter housing removed, take the opportunity to inspect the interior of the housing for any debris or dirt that may have accumulated. Cleaning the housing is essential to maintain optimal air filtration performance.
  • Cleaning Tip: Use a soft brush to remove loose dirt and debris. For a more thorough cleaning, you can wipe the inside of the housing with a clean rag or use compressed air to blow out any trapped particles.
Step 7: Replace the Air Filter (if Necessary)
If you're removing the housing to replace the air filter, now is the time to remove the old filter. Simply lift it out of the housing and replace it with a new filter that matches the manufacturer’s specifications.
  • Key Consideration: Always ensure that the replacement air filter is the correct size and type for your Bobcat L190 to maintain engine efficiency.
Step 8: Reassemble the Air Filter Housing
Once the air filter is replaced or the housing is cleaned, it's time to reassemble everything. Reverse the steps to reinstall the air filter housing, ensuring that all fasteners are tightened securely, and hoses or ducts are reconnected properly.
  • Tip: Double-check that all components are correctly aligned and that no parts are left loose, which could affect engine performance.
Tips for Proper Maintenance and Troubleshooting
  • Regular Air Filter Replacement: The air filter should be checked regularly, especially if you're working in dusty conditions. A clogged air filter reduces engine performance and fuel efficiency.
  • Visual Inspections: Periodically inspect the air intake system for signs of wear, cracks, or loose fittings.
  • Engine Efficiency: A clean air filter is essential for efficient combustion. Without proper airflow, the engine will consume more fuel and generate more emissions.
  • Consider Professional Help: If you're unsure about removing the housing or dealing with complex issues related to the air intake system, it may be worth consulting a professional mechanic or service provider.
Conclusion
Removing and maintaining the air filter housing on the Bobcat L190 is a manageable task that ensures the longevity and efficiency of your skid steer loader. By following the proper steps and performing routine maintenance, you can avoid engine performance issues and extend the life of your equipment.
Remember, the air filter is one of the most important components for keeping the engine running smoothly, and replacing or cleaning it regularly can save you significant costs in repairs and fuel efficiency down the line. With careful attention and routine care, your Bobcat L190 can continue to deliver reliable performance for many years to come.
