This piston ring is an authentic manufacturer approved replacement part. Is is commonly used on Echo gas trimmers/edgers. The purpose of a piston ring is to create an air tight seal inside the cylinder. A worn or broken piston ring will allow combustion gases to escape the seal and enter the crankcase. This would cause low compression and a loss of power. Replacing an o-ring should resolve this issue. This part is made out of metal and is sold individually. To complete this repair you will need a set of wrenches, pliers and a screwdriver. • Remove the air cleaner • Drain the fuel • Remove the air cleaner case • Remove the carburetor • Remove the intake insulator • Remove the spark plug • Remove the engine cover • Remove the insulator gasket • Remove the starter assembly • Remove the fuel tank • Remove the air duct • Separate the engine • Bind the engine • Remove the clutch • Remove the flywheel • Remove the starter pulley • Unbind the engine • Remove the muffler • Separate the cylinder from the crankcase • Remove the piston ring • Install the piston ring • Reassemble and test the equipment

This is an original Echo replacement part manufactured for use with outdoor power equipment. The piston ring is used to form a seal between the crankcase, and cylinder. Wear can occur on piston rings from dirt in the cylinder or lack of oil. A worn ring can cause damage to the cylinder, piston, and can lead to a lack of compression when the seal is broken. This piston ring is sold individually.
This piston assembly is a genuine OEM replacement designed for select 2-stroke outdoor power equipment. It restores proper engine compression and supports smooth, efficient combustion, helping bring back lost power and reliable performance. Manufactured with durable, high-quality materials for a precise fit, it’s an ideal replacement when worn piston components cause hard starting, reduced power, or poor engine operation.

This is a genuine OEM approved replacement part designed for use with Hitachi nailers. The piston is a central component of an engine. It both provides compression within the engine, as well as transfers the energy from combustion to the crankshaft (which creates rotation). This assembly includes the metal piston, ring, two retainers and the pin. Replacing the piston assembly is not the simplest repair, but it is definitely something you can do yourself. You will need a screwdriver to remove the cover and a set of sockets and wrenches for the rest of the repair.
