Parts for Craftsman 41DD386C799: Engine Assembly Parts

Also known as a rewind starter, the recoil starter assembly is the part in a string trimmer that drives the engine's combustion process. When the component is engaged, the engine can be started by hand to create sufficient speed to bring all of the operating systems on board. In cases where there is damage to the recoil starter assembly, the trimmer will not turn on.Wear and tear from frequent or extended use can cause the recoil starter assembly to fail. The most common symptom of a broken or damaged recoil starter assembly is a slack pull rope. If this happens, the recoil starter will need to be replaced as the equipment cannot be used without a working recoil starter. Replacing the part will require a set of work gloves and basic tools. The housing cap and rope should be removed before replacement.This recoil starter assembly is an authentic OEM replacement part that is directly sourced from the manufacturer. It is sold as an individual part. The starter assembly is compatible with several string trimmers manufactured by Craftsman, MTD, and Troy-Bilt.

Few parts fulfill as many roles on lawn mowers and other landscaping power tools than the cover screw. This screw serves to attach metal housing parts, assemblies, and shrouds to one another on equipment such as power vacuums, snow blowers, edgers, tillers, hedge trimmers, lawn tractors, leaf blowers, grass trimmers and cultivators. As these are extremely durable metal screws, they seldom fail under ordinary use. It should be noted, however, that they are most often used at connection and pressure points. Stresses at these junctions sometime loosen screws, causing them to be lost or occasionally resulting in stripped threads. It's also occasionally the case that these screws are lost during repair or routine maintenance of yard equipment because of their small size. Users should make sure to consult their owner's manuals for replacement steps and any special instructions. Because of their small size and the ease of losing them during repair work or maintenance, it's recommended to keep a supply of appropriately sized screws on hand. Most importantly, when replacing a part make sure to use a genuine OEM replacement part. They are manufactured according to the specs of the original parts and are perfect replicas.

The design and purpose of the O-ring is relatively self-explanatory. It is an “O” shaped ring used as a gasket in lawn and garden equipment. It is designed to sit within a groove and be compressed during assembly. It creates a perfect seal that blocks the path of liquids or gases from escaping or flowing into regions of the machine where they are not supposed to be.The O-ring may be damaged if an outdoor piece of equipment is struggling to start or run. After checking the air filter cover, removing the carburetor, and cleaning it thoroughly, the next step is to replace the O-rings, carburetor gasket, and air filter, followed by the spark plug. Regular maintenance of the carburetor and routine evaluation of the suitability of the O-ring is essential to proper mechanical maintenance.This O-ring is a genuine OEM part sourced directly from the manufacturer, and it is sold individually. The manufacturer of this product is MTD. Examples of compatible products and machines includes trimmers, tillers, weed wackers, brush cutters, and leaf blowers or leaf vacuums.

These O rings are replacement parts intended for use in a number of gasoline-powered lawn trimmers. The O rings serve as gaskets and are placed at the entry and exit points in the carburetors where gasoline and air are mixed and the expansion powers the trimmer. Though constructed of durable material, periodically the flow of the air/fuel mix or the rush of expanding air will cause damage to occur to the O rings so they become less resilient and the carburetor functions less efficiently. In these cases, users often decide to replace not just the element of the carburetor but the O rings as well. Users may notice problems with the carburetor when they cannot get an adequate adjustment, allowing the trimmer to function smoothly. They may also have trouble getting the trimmers to start at all or run without smoking. To replace the O rings, remove the air filter cover and carburetor. Once the carburetor has been cleaned, and the gasket and filter replaced, add a fresh mix of 40:1 fuel. The trimmer should start immediately. These OEM certified O rings are compatible with Bolens, Troy-Bilt, Yard Machines, and Craftsmen trimmers.

This carburetor is a device for supplying a two-cycle engine with a mixture of air and fuel. This part comes pre-assembled and has a plastic choke lever along with a metal body. The primary purpose of a carburetor is to mix the right amount of fuel with air so that the engine runs properly. If enough fuel is not mixed with the air, the engine runs lean and can either stop running or gets damaged. On the other hand, if too much fuel is mixed with air, the engine runs rich, and it either floods, runs poorly, runs very smoky, or wastes fuel. The carburetor is in charge of getting the right mixture. If the carburetor is clogged, the engine will not get enough fuel. It may not start or may run rough. The procedure to replace the carburetor is quick and easy, taking only around 15 minutes, but it is recommended to work in a ventilated area. This carburetor works with outdoor power tools like the trimmer, leaf blower, and tiller. It is compatible with specific products from popular brands like Craftsman, MTD, Murray, and Troy-Bilt. It is sold individually and is supplied directly from the original equipment manufacturer.

A carburetor gasket is a thin rubber material that provides a seal between two parts. Its primary purpose is to prevent fuel and air leaks. This gasket is installed between the air cleaner and the carburetor. Over time, it can crack and tear due to heat and fuel exposure. When this happens, the carburetor may produce the wrong combustible mixture for the engine. In return, the engine may experience rough idling and flooding. A carburetor gasket replacement is necessary. MTD makes this carburetor gasket replacement. It is manufactured to fit string trimmer, leaf blower and tiller made by MTD, Bolens, Troy-Bilt, and Craftsman. This brand-new carburetor gasket is sold individually. A fully assembled carburetor and O-ring are sold separately.
