Trimmer Engines

Trimmer Breather Assembly This breather, also known as a fuel tank vent, is a genuine OEM replacement part used in trimmers and edgers. It is responsible for managing the pressure and air flow inside the fuel system, by acting as a valve for the fuel tank. It allows clean air to enter the tank, while preventing dirt and debris from entering as well. Over time, the breather can crack or become clogged leading to restricted air flow, inconsistent fuel supply, fuel leakage, hard starting, and engine stalling. Locate the breather on or near the fuel tank and disconnect the hoses and fasteners attached to it. Depending on your model you may need to remove the fuel tank to complete this replacement. Place the new breather in position and reattach the hoses and fasteners. Test the new part by gently blowing into the breather to confirm that the air flow is not restricted.

This OEM Piston Ring is used to provide a seal between the piston and cylinder wall. It attaches around the piston, inside the groove. It will require a screwdriver, allen wrench, torx wrench and socket set and is rated as "Hard" to install. The part is silver, metal, and individually sold. If broken due to general wear/fatigue you will have poor compression within the cylinder, causing a loss of power. If broken, damaged or worn, the part should be replaced. Refer to your make, model, and diagram to ensure this is the correct part.

Trimmer Piston Ring 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

Trimmer Piston Ring This genuine manufacturer sourced replacement part is specially made for use with a variety of handheld lawn and garden equipment. This part is installed on top of the piston/connecting rod. Its purpose is to create a seal in the cylinder so that it can build pressure. A worn or broken piston ring will allow combustion gases to escape the seal and enter the crankcase, causing low compression and a loss of power. If compression is reduced significantly, the engine will not run at all. Includes one (1) metal piston ring. Tools Required: Receptacle for draining fuel, Torx wrenches, spark plug wrench, 10mm wrench (or adjustable), long-nosed pliers, rubber mallet, standard screwdriver, old starter rope (or similar cord), adjustable pliers, 2-cycle engine oil, razor blade, ignition gapping gauge. • 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

This metal ring in your engine, known as the piston ring, seals the gap between the piston and cylinder wall. It makes sure that the gases produced during combustion do not escape and that the engine maintains the pressure it needs to run. If the piston ring is damaged, oil can seep into the combustion chamber, causing your engine to exhibit rough idling and your machine emit blue smoke. To switch out a defective piston ring, detach the old ring from the piston with a screwdriver. When installing the new ring, you may need to compress it to make it fit properly. Please be aware that this genuine OEM replacement part is bought individually. It is recommended that you replace all the piston rings in your machine at once, as they tend to wear down at the same rate. Carefully review your user manual to determine how many rings your machine needs before placing your order.

The Breather allows air to enter the tank, so no vacuum is created as the fuel level drops, which would prevent the flow of fuel to the carburetor.It seals in the gas emissions and fuel at the same time. It is a metal and rubber part, sold individually, rated as "Easy" to install. If damaged, fuel may start leaking from it, and it must be replaced. The part is attached inside of the fuel cap. Refer to your make, model and diagrams to ensure you're choosing the right part.

Trimmer Ring-piston 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.

Trimmer Piston Kit 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.
