Parts for Mtd 41AD25SC793: Engine Assembly Parts

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.

In this case, pliers might be needed to remove the faulty screw. Otherwise, this repair should be fairly simple and only require a screwdriver. Be sure the machine is powered down before replacing this part. This specific screw is sold individually and is a genuine OEM replacement part. Be sure to purchase the correct amount as many devices require more than one.

This is a replacement spark plug that is designed specifically to be used with select string trimmers. the spark plug is connected to the ignition module and is responsible for creating the spark that starts the internal combustion engine. Over time, the electrode on the spark plug will wear down. Other issues can also arise that cause the spark plug to foul or stop working. Spark plugs are part of routine maintenance on any engine, but most owners keep a spare or two around just in case of emergencies. In the event that the spark plug is bad, the engine will not start. This genuine OEM spark plug is manufactured by MTD and designed for use in select trimmers. It is compatible with over 50 models of string trimmers from MTD, Bolens, Murray, Troy-Bilt, Yard Man, and Cut Cadet. Owners will need to consult their product diagram or manual to find the exact gap for the spark plug when replacing them.

Be sure to wear gloves for hand protection when replacing spark plugs and performing other maintenance.

This replacement part is an o-ring. It is a genuine replacement part made by MTD. O-rings are small but are a very important part of many appliances. These rubber rings are placed around parts that have spaces in their vicinity. This blockage created by the O-ring allows gas and air to stay within the engine or appliance. Otherwise, it might escape and cause issues during use. A new o-ring might be needed if the current ones are missing or becoming thin. This is common in many appliances. If there is a noticeable amount of air or gas escaping the appliance then it might be caused by a gap where an o-ring should be. This o-ring is sold individually. Be sure to purchase the correct amount as many appliances require more than one. This is a genuine OEM part sourced directly from the manufacturer.

This is an insulator assembly includes the insulator, seals, and hardware. It is designed to create the right spacing between the cylinder and carburetor on many blowers and trimmers made by various manufacturers. The insulator assembly also keeps heat from moving between the other components. Over time, the insulator assembly can become damaged or crack. When this occurs, air can reach the engine and create a condition where the engine can't perform at its best. If this happens, the insulator assembly will need to be replaced. Take off the air filter, drain the fuel, and remove the intake assembly. The insulator can be taken off of the engine before the replacement is added. Use mounting screws to fit the insulator to the other components.

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.

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.

The clutch assembly uses centrifugal force to connect the shafts and create the drive shaft motion that powers the machine. The drive shaft nests inside the other shaft, and over time these parts can wear and become damaged with regular use. Today's parts can even continue to function long past when they should, so it may not be apparent that a clutch assembly needs to be replaced until the entire unit is bad.

This genuine MTD muffler assembly can be used as a replacement part for a string trimmer, a leaf blower, or a leaf vacuum. The muffler assembly contains a replacement muffler and the components that collectively fasten the muffler to the appliance. The purpose of a muffler for one of these outdoor appliances is to silence or soften the engine and to filter the air that exits the engine to direct the exhaust away from the person operating the appliance.A muffler might suffer damage in the lifespan of an appliance that could necessitate its replacement as well as the replacement of its associated components. If the muffler is no longer softening the noise of the appliance or if the exhaust blows unfiltered air directly toward the operator of the appliance, these are symptoms that the muffler should be removed and replaced with this genuine OEM part.

This o-ring is a genuine OEM part sourced from the manufacturer for use in many parts of engines in lawn and garden equipment. The o-ring is a type of gasket but is not flat like a gasket. It is circular and made of rubber. It is seated in a groove on the engine part and is compressed against another part to create a seal. This seal keeps air and fluids from entering or exiting the sealed part. Like gaskets, o-rings must be periodically inspected and replaced to ensure proper engine performance.Visual inspection of o-rings will reveal nicks, indentions, cuts, or tears on the surface of the o-ring. If the rubber has warped due to excessive heat, it will not fit properly and will need to be replaced. The replacement may not require tools, depending on the location of the rubber gasket. Remove the bad o-ring and wipe both sides of the area to remove the old grease. Apply fresh grease to the o-ring before installing it to ensure a tight seal. Press the new o-ring firmly in the groove before attaching the connecting part. If the ring does not seat well or has to be stretched to fit, discard and start with a new o-ring.The o-ring is sold individually. It is designed for trimmers and tillers. It is compatible with Craftsman, MTD, Bolens, Troy-Bilt, and Cub Cadet.
