Engine

The piston ring provides a seal between the cylinder wall and the piston, attaching inside the groove around the piston directly. It is responsible for keeping the combustion gases in the cylinder and preventing them from entering the crankcase. The piston ring may break down with general use over time or it may break unexpectedly due to some kind of damage or other mechanical failures. This creates poor compression in the cylinder and can result in a loss of power to the equipment. Significant leaks could result in an engine that won’t run at all. The Husqvarna piston ring is a genuine OEM part from American Yard Products, who manufactures equipment and parts for leading industry brands, including Husqvarna, Craftsman, Poulan and Poulan Pro, Weed Eater, Sears/Roper, Rally, Electrolux Home Products, and Yard Pro. This piston ring fits several models of leaf blowers and trimmers from the brands listed. Refer to your user manual parts diagram for exact part compatibility.

Combustion engines operate because of the chambers that seal in the tiny explosions caused by fuel, air and a spark. The pistons are part of the process of taking power from those explosions, and the piston rings seal the combustion chamber so that all of the gases created remain inside of the engine's crankcase. This replacement piston ring will ensure that a chainsaw's engine can do that, as well as maintaining the right amount of oil between the piston and the cylinder wall. An OEM replacement part, this piston ring works with Craftsman and Husqvarna chainsaws, among others. It will require a wrench set, screwdriver and a pair of pliers to make the replacement. Sold individually.

Carburetors mix fuel with air to ensure the engine gets just the right amount of combustion. It works when idling and when in operation, and a chainsaw carburetor requires an adapter. This reduces vibration to the carb and isolates heat to help keep the carburetor cool. This carb adapter kit will connect the carburetor to the cylinder and uses a gasket on either side that can fail and require replacement. Because plastic can be used for a carb adapter, it can crack and lead to failure. This OEM carb adapter kit is meant for Craftsman, Poulan and Husqvarna chainsaws, and will work in many different models. Replacing it will require the use of a wrench set, socket set, pliers, and screwdriver. As noted, gaskets may also be needed, but this part is sold individually and includes only the chainsaw carb adapter.

This part is a replacement connecting rod. This is a genuine OEM part made by Midwest Engine and has been sourced directly from the manufacturer. This part can be used to replace a defective or broken connecting rod in outdoor power equipment. This part connects the crankshaft in the equipment's engine to the piston. It is essential for proper functionality and will need to be replaced if broken, faulty, corroded, or ineffective in any way. When working on or near an engine, it's important to ensure that the equipment is powered off and completely cool before beginning any repairs. For more accurate information on how and where to place this connecting rod, the appropriate owner's manual and equipment diagrams should be referred to. As an authentic replacement part, this connecting rod is suitable for use on outdoor power equipment manufactured by Midwest Engine, Briggs and Stratton, and other brands. Please note that this is a genuine part made of high-quality, durable metal and is sold individually.

This replacement part is a flywheel. This is a genuine replacement part made by MTD. This part is a large rotating piece, similar to a wheel, that provides the engine with rotational energy that is later converted to other types of energy so that the engine can operate smoothly. A new flywheel might be needed if the current one is missing or damaged. If the user hears unusual noises coming from inside the engine area, the flywheel might be out of place and not working properly. If this is the case, it might be best to replace this part. Be sure the engine is completely powered down and cooled off before repairing this part. This part is sold individually and is sourced directly from the manufacturer. This part is a genuine OEM replacement part to ensure proper fit and long-lasting use.

This replacement part is a piston pin. This is a genuine replacement part made by MTD. This part is small but important to ensure that the piston is working properly during use. A new piston pin might be needed if the current one is missing or damaged. It is not uncommon for the pin to be stripped down over time due to normal wear and tear. The pin may also become lodged in place and should be replaced if this happens. Wear work gloves when completing this repair to prevent injury during the job. The engine should be completely turned off and cooled down before beginning repairs.This part is sold individually and is sourced directly from the manufacturer. This is a genuine OEM replacement part.

This is an MTD rocker arm. The rocker arm works in conjunction with the engine and head. The job of the rocker arm is to push the intake valve open, allowing fuel and air to enter the cylinder. Since the rocker arm is a part of the head gasket system, any damage can cause the engine to run extremely weak. There could also be a noticeable clicking or ticking noise originating from the engine area of the mower. A visual inspection of the rocker arm will confirm any damage. Begin the repair by removing the muffler guard. After removal, move to the valve cover and remove that guard as well. Disconnect the fuel and air lines running to the head. Remove the spark plugs in the valve section. Finally, the rocker arm can be removed using a socket wrench. Repeat these steps in reverse to install the new rocker arm.This product is sourced directly from the manufacturer as a genuine OEM part. The component is available individually, separate from the original machine. This part is compatible with MTD and Cub Cadet brand equipment.

This replacement part is a piston, and it is intended for use in different types of lawn equipment. This is a genuine replacement part made by MTD. This piston is commonly found in lawn mowers and is an important part in the user process. Pistons help transfer the combustion power of the engine to other working parts of the machine. A new piston might be needed if the overall performance of the engine is lacking compared to previous uses. If the lawn mower is not able to build enough power to accelerate, the piston might be faulty. It is also common for the engine to use an excessive amount of oil or put out white or gray exhaust smoke. All of these indicators might mean that the piston should be replaced. This part is a genuine OEM replacement part. This piston is sold individually and can be used in lawn mowers manufactured by MTD.

This is a piston ring set for use in various types of small engines. Piston rings help to maintain the gas compression between the cylinder wall and the piston. They ensure that the gas generated during ignition does not leak. When the piston rings go bad, it could result in gray or white smoke from the exhaust, poor performance, and excessive oil consumption.Dirt and normal wear and tear can take a toll on the piston rings. Fuel flooding could also cause damage to the rings. Poor lubrication could cause problems with the piston rings, as well. If there are problems with the rings, owners will want to replace them soon. These piston rings are compatible with certain machines from Cub Cadet, MTD, Yard Machines, Troy-Bilt, Columbia, and Craftsman. This piston ring set is sold individually and comes with four of the piston rings. They are genuine OEM parts that have been sourced from the manufacturer and are made from high-quality material.

This replacement part is a flywheel. This is a genuine replacement part made by MTD. This part is found inside many different engines and is responsible for rotating to help the engine run smoothly and effectively during use. A new flywheel might be needed if the current one is missing or damaged in any way. This part can become stripped or worn down over time and it is recommended that it be replaced if this is the case. If the wheel has moved off its track, a repair might be possible. Be sure that the engine is completely shut down before replacing this part.
