The sweet smell of freshly cut grass is a hallmark of summer. But that idyllic image quickly turns sour when your Craftsman lawn mower sputters and coughs, its once-powerful engine struggling to do its job. The culprit? A dirty air filter, choked by dust, debris, and the remnants of last year’s grass clippings.
This article will guide you through the simple process of changing your Craftsman lawn mower’s air filter, ensuring your mower runs smoothly and efficiently, season after season. We’ll cover identifying the air filter, choosing the right replacement, and the step-by-step process for installation. By the time you’re done reading, you’ll be a pro at maintaining your lawn mower’s air intake system, ensuring a healthy engine and a beautifully manicured lawn.
A Clean Air Filter: The Key to a Healthy Engine
A lawn mower’s air filter acts as the engine’s first line of defense against dirt and debris. The air filter traps dust, grass clippings, leaves, and other particles before they can enter the engine’s combustion chamber. This prevents wear and tear on sensitive engine components, ensuring smooth operation and long-term performance. A clogged air filter restricts airflow, causing the engine to run poorly, leading to decreased power, increased fuel consumption, and even engine damage.
Locating the Air Filter
Before you can change the air filter, you need to find it! Craftsman lawn mowers typically have their air filters located in one of two places:
Under the Engine Cover
Many Craftsman mowers house the air filter under the engine cover. To locate it:
- Identify the Engine Cover: The engine cover is a metal or plastic housing that protects the engine from debris.
- Locate the Filter Housing: Look for a small, rectangular or cylindrical housing attached to the engine cover. It might be labelled “Air Filter” or have a simple arrow pointing to it.
- Open the Housing: The filter housing usually has a clip or latch that you can easily open.
On the Side of the Engine
Some Craftsman mowers place the air filter on the side of the engine.
- Look for a Cover: The air filter will be housed within a plastic or metal cover, often with a simple latch or clip.
- Identify the Air Filter: The filter itself will be a rectangular or cylindrical element inside the housing.
Choosing the Right Replacement
Now that you’ve found your air filter, it’s time to pick the right replacement.
- Match the Original: The easiest way is to simply match the dimensions and shape of your existing air filter. Look for the manufacturer’s information on the filter itself, such as the brand, part number, or model number.
- Check your Owner’s Manual: Your Craftsman lawn mower’s owner’s manual should have a list of recommended replacement parts, including air filters.
- Visit a Hardware Store: If you can’t find the specific part number, head to your local hardware store. They can help you find a compatible air filter based on your mower’s model.
Changing the Air Filter: A Step-by-Step Guide
With the new air filter in hand, it’s time to swap it out. Here’s a step-by-step guide:
Step 1: Prepare the Mower
- Safety First: Make sure the mower is turned off, the spark plug wire is disconnected, and the engine has cooled down completely. This prevents accidental starting and potential injury.
- Clean the Work Area: Clear the area around the air filter housing of any debris or loose grass clippings. A clean workspace will make the process smoother.
Step 2: Remove the Old Filter
- Open the Housing: Carefully release the clips or latches holding the air filter housing closed.
- Remove the Filter: The old air filter should slide out easily. Take a moment to inspect it. If it’s heavily clogged, it’s time for a replacement.
Step 3: Install the New Filter
- Position the Filter: Align the new air filter within the housing, ensuring it sits snugly without any gaps or obstructions.
- Secure the Housing: Carefully close the air filter housing, making sure the latches or clips are securely fastened.
Step 4: Test and Enjoy!
- Reconnect the Spark Plug Wire: Carefully reattach the spark plug wire.
- Start the Mower: Start your Craftsman mower and let it run for a few minutes. You should notice a smoother, more powerful engine performance.
Maintenance Tips and Additional Information
- Change the Filter Regularly: To ensure peak performance, change your air filter every 25 hours of use or at the beginning of each mowing season, whichever comes first.
- Clean the Filter: If you see a minimal amount of dirt or debris, you can try cleaning the air filter with compressed air or gently tapping it against a hard surface. However, this is only recommended for filters with minor dust accumulation and is not a substitute for regular replacement.
- Inspect the Housing: While you’re changing the filter, take a moment to inspect the air filter housing for any cracks or damage. If you see any, replace it with a new one.
- Store Filters Properly: Keep your spare air filters in a clean, dry place, away from dust and debris.
