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.

The piston ring is used in internal combustion engines in small outdoor power equipment. This ring creates a strong seal between the cylinder and the piston, separating the crankcase from the combustion chamber. If the piston ring degrades or fails, it can cause dangerous gases to leak from the engine. This leak can also affect the performance of the engine because of the reduced compression. In severe cases, the engine could fail completely until the piston ring is replaced. The cylinder should be inspected for damage when replacing the ring, but generally this replacement will do the job. This genuine OEM piston ring is manufactured by Echo and designed to be used with a number of engines in machines from Shindaiwa, Little Wonder, and Echo. This part can fit over 150 blowers, trimmers, pruners, cultivators, and vacuum machines designed for outdoor use. Allow engines to cool completely before doing any repairs and wear gloves for hand protection. This piston ring is sold as an individual unit and does not include any other parts or hardware.

This is a cylinder head used in several types of lawn and garden equipment. The cylinder head is the component that sits on top of the engine. It is responsible for closing the combustion chamber. The gap in between the head and the engine is filled with a head gasket. The cylinder head also helps ensure that the cylinder stays properly lubricated at all times. If the cylinder head has failed, it can cause dropped engine performance, low oil levels, and smoke may come from the exhaust.If the cylinder head needs to be replaced, the grass screen and shield will need to be removed. Take the bolts out of the engine cover before removing the cover. Remove the engine shroud and the bolts that hold the pump bracket to the head. The valve cover should be removed to find the cylinder head. Take the old one out and insert the new one before reassembling the equipment.This cylinder head is a genuine OEM replacement part that is directly sourced from the manufacturer. It is sold as an individual part. The cylinder head is compatible with hedge trimmers, leaf blowers, and chipper shredders made by Shindaiwa, Mantis, and Echo.

This is a genuine replacement piston kit for select Echo lawn and garden equipment engines. The piston is located inside the cylinder and is responsible for linking with the connecting rod. This helps separate the crankcase from the combustion chamber. The piston will move up and down during ignition, which drives the crankshaft and helps propel the engine. Due to constant heat and repetitive motion, this assembly can wear out or become damaged over time, necessitating a replacement. This genuine OEM piston kit is manufactured to exact specifications and includes the piston, ring, clips, and pin. It is compatible with select blowers and vacuums, hedge trimmers, cultivators, edgers, and trimmers. This part can be used with machines from Echo, Shindaiwa, and Little Wonder. It is sold as an individual kit and only includes the items mentioned. Replacing the piston kit will require allowing the engine to cool so that the cylinder can be disassembled. Then, the old piston and accessories can be removed and the new one can be installed. A screwdriver and pliers will be needed for this repair. Always work in a well-ventilated area and wear gloves when performing engine repairs.

This cylinder gasket replaces a part used by Echo, Little Wonder, and Shindaiwa in some of their small gasoline-powered engines. These engines are typically used in landscaping and lawn tools such as hedge trimmers, power vacuums, chippers, leaf blowers, pole saws, grass trimmers, pruners, and cultivators. This gasket sits between the cylinder and the crankcase of these small engines. It provides a seal that stops air from getting into the combustion chamber, and lubricating oil from leaking out of it. While gaskets such as these are intended to be durable, eventually the heat, expansion, and pressure experienced by the gasket will cause it to lose the ability to seal. Most often the signs of gasket failure are oil leaks around the base of the manifold and white, oily smoke emitted while the engine is running. Replacing the cylinder gasket is one of the more involved repairs a user will experience. To make certain that it is accomplished properly, it is advised that the user consult the owner's manual, an online diagram of the engine parts, and the manufacturer's website for instructions. The cylinder gasket, which is sold as an individual unit, should be replaced with one like this, which is a genuine OEM replacement part.
