Remove An Old Rusty Muffler From A Push Mower

The muffler on your push lawn mower reduces the noise coming from the engine. Over the course of time soot begins to build up inside the muffler. The muffler also begins to rust and develop holes. This makes the muffler ineffective in reducing the engine noise and also allows the fumes and smoke to pass through. Before purchasing a new muffler remove the old rusty muffler first and take it with you. This way you can endure you buy the correct size muffler for your mower. Does this Spark an idea?

Instructions


1. Shut off the push mower and allow the engine to cool completely. While the engine is cooling, visually inspect the muffler to determine how it attaches to the engine. Some mufflers use bolts that have the corners of the mounting plate bent over them, while some simply screw into the side of the engine.


2. Bend back the tabs on the mounting plate with a pair of needle nose pliers, if your muffler uses mounting bolts.


3. Turn the mounting bolts counterclockwise with a socket wrench. If the mounting bolt becomes difficult to turn, do not force the bolt. Forcing the bolt could cause it to break off inside the crankcase. Turn it back clockwise one full turn and spray some penetrating lubricant around the threads.


4. Allow the penetrating lubricant to work for 20 minutes and attempt to remove the bolt again. Continue doing this as much as necessary to remove the securing bolts.


5. Look for a ring around the neck of the muffler near the engine, if you have the screw-on type. Tap the end of the ring counterclockwise with a flat-head screwdriver and hammer.


6. Apply some spray lubricant to the threads where they meet the side of the engine. Grasp the neck of the muffler with a pipe wrench and turn it counterclockwise to remove the muffler from the engine.
