Instructions
Step 1: Shut off the engine
Ensure that the engine is off and cool before you start working on the mower.
Step 2: Prepare the safety gear
Put on your safety goggles to protect your eyes from debris.
Step 3: Locate the muffler
The muffler is usually attached to the exhaust pipe on the side of the engine.
Step 4: Remove the old muffler
Use the wrench to loosen the bolts or nuts holding the muffler in place. Be careful not to drop the bolts into the engine compartment.
- If the muffler is rusted or corroded, you may need to use a penetrating oil to loosen the bolts or nuts.
Step 5: Remove the old muffler gasket
Use a flathead screwdriver to remove the old muffler gasket if there is any.
- Be careful not to damage the exhaust pipe or the engine.
Step 6: Apply a thin coat of anti-seize compound to the exhaust pipe
This will make the new muffler easier to remove in the future.
Step 7: Install the new muffler gasket
Center the new gasket over the exhaust pipe and press it into place.
Step 8: Install the new muffler
Position the new muffler over the exhaust pipe and secure it with the bolts or nuts you removed earlier.
- Tighten the bolts or nuts until they are snug.
Step 9: Test the muffler
Start the engine and let it run for a few minutes.
- Listen for any leaks or unusual noises.
- Ensure the smoke coming out is free of unusual fumes or colors.
Step 10: Turn off the engine
Turn off the engine and let it cool down completely before storing the mower.
Congratulations, you have successfully replaced the lawnmower muffler!
