Lawn Mower Engine

Breather assembly for chainsaw and lawn equipment engines. Vents excess air from the crankcase. Replace if cracked, broken, or worn to maintain proper engine ventilation.

Piston rings help to maintain the pressure between the piston and cylinder wall. If the compressed gas between these two parts begins to leak out, the engine will not be able to put out enough energy, and the lawn appliance will stop working. Piston rings can wear out over time due to engine overheating or faulty ignition in the engine. A telltale sign of a burnt-out piston ring is whitish-grey smoke coming from the appliance. Extreme oil inefficiency is another sign. This part is a genuine OEM part designed for Echo or Mantis handheld yard tools such as a chainsaw, hedge trimmer, leaf blower, edger, pole pruner, or tiller engine. It does not ship with other parts. Any additional parts needed to install the piston ring must be ordered independently.
