Echo Engine Engines

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 is a genuine OEM sourced replacement part that has been sourced from the original manufacturer to be used with trimmers, hedge clippers, pruners, edgers, and blowers. The piston fits inside the cylinder and links with the connecting rod. The piston is used to separate the combustion chamber and the crankcase. The piston moves up and down inside the cylinder during the ignition sequence and this action drives the crankshaft. This kit includes the piston, ring, clips, and pin.

This piston kit is designed for 2-stroke outdoor power equipment to restore proper engine compression and original performance during a top-end repair. Supplied as a complete OEM set with the piston and related components, it helps resolve issues such as hard starting, loss of power, or reduced efficiency caused by internal wear. Built for precise fit and durability, it’s a practical replacement for maintaining reliable operation and extending engine service life.

This piston kit is used to repair or rebuild small 2-stroke engines, helping restore proper compression and engine performance. Typically including the piston, rings, and retaining components, it’s a direct replacement for worn or damaged internal parts and is commonly installed during top-end engine service to correct power loss, hard starting, or low compression.

This is a genuine replacement part sourced directly from the manufacturer. The piston kit is commonly found in yard equipment from Echo, such as backpack blowers, trimmer/brushcutters, and edgers. This kit includes the piston, piston pin, two piston rings, a needle bearing, two washers, and two piston pin retainers. You may require pliers and an Allen wrench or screwdriver when replacing this item.
