Spark Arrestor Kit
Genuine Husqvarna part
By: Husqvarna
Part Number: 545006056

This is a genuine replacement spark arrestor kit that is used with certain styles and models of chainsaws. The spark arrestor kit will attach to the cylinder gasket and is designed to catch any particles that are coming from the engine that are hot or likely to create a fire risk. This ensures that the internal combustion engine can operate effectively. When the spark arrestor is damaged or worn, or if pieces go missing, it will not be able to give the engine the protection from flammable debris that it needs. A replacement is necessary for the safe operation of the chainsaw. This OEM authentic spark arrestor kit is manufactured by Poulan and compatible with over 50 of the chainsaws that are made by the brand. This kit includes the screen, the metal arrestor, and the nut that connects the components and helps secure the entire assembly to the engine's cylinder gasket. This part replacement will require a nut driver and a set of pliers. Allow the engine to cool completely and always disconnect the spark plug when performing engine repairs or internal replacements. Owners will want to wear gloves for hand protection, as well.
