The flywheel is a heavy metal wheel that connects to the rotating shaft. Its purpose is to help regulate how power is delivered from the motor to the rest of the tool. Its weight and inertia oppose and moderate small changes in the speed of the engine and holds onto that energy for use when needed. The most common problem with flywheels is for them to crack. As the engine begins to age and other parts begin to break down, excess vibration in the engine can cause the flywheel to wear down, grate, and even shatter. The flywheel needs replacing when the motor begins slipping into the wrong gear. The exact steps for replacing the flywheel will depend on the specific model being repaired. It should only require a screwdriver. This is a genuine OEM replacement flywheel assembly for gardening hand tools like leaf blowers, edgers, weed eaters, and hedge trimmers made by Craftsman, Husqvarna, Weed Eater, Poulan, Poulan Pro, Paramount, Turf King.

Craftsman manufactures this cylinder head bolt that fastens the cylinder of a small gasoline-powered engine to the engine manifold. There are often two head bolts that secure the cylinder. The placement of the bolts is important as it not only fastens the two engine parts together, but holds the cylinder gasket in place, as well. Among the equipment that uses this type of cylinder head bolt are leaf blowers, power vacuums, grass trimmers, edgers, and hedge trimmers. While it is rare for the bolts to fail, the gasket they hold in place can sometimes wear and allow oil to leak outside the engine manifold or into the combustion chamber. This is revealed by white, oily smoke or an abundance of oil on the equipment. When replacing the head gasket, it is a good idea to replace the cylinder head bolts, as well, as they will have received a good deal of wear, potentially weakening them. These bolts are sold separately, so the user should make sure to purchase the correct number of bolts needed. Before beginning, the user should consult diagrams of the internal engine parts and their order. These bolts are OEM genuine replacement parts, built to match the factory originals.
