A flange nut's unique wide flange design distributes the nut's pressure over the part it is securing. In return, it creates an even fastening surface, which reduces part damage and nut loosening. This one-piece all-metal fastener has a lock nut version that features a protruding circular flange. This drastically increases bearing surface, compatibility either for irregular or oversized holes, and surface tension reduction. Flange lock nuts are the preferred type of fastener for many lawnmower models because it can provide better fastening than regular screws, which are known to loosen under extreme vibration. However, it’s important to know that flange lock nuts are susceptible to wear and tear due to constant vibration exposure. It is essential to replace the broken flange lock nut immediately to prevent serious damage to the lawnmower. The MTD 712-04063 Flange Lock Nut OEM replacement can be used with Craftsman, White Outdoor, Yard Machines, MTD, or Columbia lawnmowers. It is a genuine or OEM MTD replacement part that measures 5/16-18. It is threaded and requires the use of a wrench. This replacement flange lock nut is sold individually. An MTD bolt carriage may also be needed and is sold separately.

This is a fuel tank for MTD string trimmers. It’s constructed from white resin, which combines the tank and mounting flanges in a one-piece, molded design. The gas cap is glossy black plastic, and the tank and primer leads are both already installed. There are two mounting screws included in the kit, making installation more convenient. This is a 2-cycle fuel tank designed for engines that run on a mixture of oil and gas. Ordinary gasoline can cause damage to the fuel lines. Tanks should ideally last for several years but can get damaged, causing a leak. Gas tank leakage is a significant safety issue and must be fixed immediately. Tanks may also need to be replaced if they become extremely soiled. To replace the tank, you will simply need to disconnect the old tank’s fuel lines and remove the two mounting screws. In addition to MTD trimmers, this tank is also used on some Troy-Bilt and Cub Cadet models. This is an OEM part sourced directly from the manufacturer, and it is sold individually.

This fuel tank assembly stores fuel. It is made from a thick plastic material. The assembly includes the fuel tank, fuel cap, and fuel lines. Although it is generally durable, exposure to fuel chemicals and the environment can eventually cause fuel tank leaks. When this happens, the fuel leak may damage other components. To install a new tank assembly, make sure to drain the old tank first. Detach the fuel lines and then use a screwdriver to remove its mounting screws. This replacement will take less than 10 minutes to complete. MTD makes this brand-new fuel tank assembly. This replacement includes the tank itself, the fuel lines, fuel cap, and mounting screws. All of which are sourced directly from MTD. It is compatible with string trimmer models from Bolens, Yard-Man, Murray, Craftsman, Yard Machines, MTD, Cub Cadet, and Troy-Bilt.

This replacement part is a hex bolt. It is a genuine replacement part made by MTD. Hex bolts are named because they are shaped like a hexagon and are different from the regular circle-shaped bolts. These parts are able to hold other parts secure and in place so that everything can operate as needed. A new hex bolt might be needed if the current ones are damaged in any way. It is possible that these bolts become stripped or lodged in place over time due to normal wear and tear and should be replaced. The repair should be fairly easy, only requiring a screwdriver or pliers if the previous part is stuck. Be sure the engine is completely powered down before beginning this repair. This bolt is sold individually. Be sure to purchase the correct amount as many appliances require more than one. This is a genuine OEM replacement part sourced directly from the manufacturer.

This steering gear is an integral part of the guidance mechanism for riding mowers and lawn tractors. This gear meshes with the turning mechanism of the wheels, connecting the front axle to the steering column. The constant, short diameter turning of riding mowers puts a tremendous amount of pressure on the steering pinion gear as well as the steering plate, causing the teeth of each of these parts to wear out. Over time, the steering will become less responsive until eventually the drive wheels will not respond at all when the steering wheel is turned. This is usually an indication that the steering pinion gear is stripped and must be replaced. Replacing this gear involves removing the nut and bolt that fix the gear to the mowing housing. Often, the bushing that sits beneath the pinion gear also needs to be replaced because of wear, and this is the best time to do that, as well. It's also a good idea to see if the steering plate teeth are also worn, as this is the ideal time to replace it as well. All parts should be replaced with genuine OEM parts, manufactured, as this replacement part is, according the specs of the original part. This pinion gear is compatible with Huskee, Murray, Bolens, Yard Man, Troy-Bilt, MTD, Yard Machine, and Cub Cadet riding mowers. This part sold individually.

A carburetor is responsible for combining fuel and air into the right combustible mixture. When it is malfunctioning, there are several warning signs to look out for. These include poor fuel economy, rough idle, flooding, and engine misfire. Installing a brand-new carburetor can help. A carburetor replacement is easy and starts with turning off the lawnmower. Open its air filter cover and use a screwdriver to remove the air filter base. Once detached, disconnect the throttle cable and fuel line. Place the new carburetor and connect the fuel line and the throttle cable. Put back the air filter base. This is a brand-new and original MTD carburetor.

Additional carburetor gaskets are sold separately.

The nut-hex flange 5/8-18 features a hex nut with a wide flanged portion at one end. This flange will act as an integrated washer that does not spin. Since the flange acts as a washer, it ensures that the nut can fasten to the material's surface evenly. If any of these nuts are removed from a machine to do other work, it is recommended to replace them with a new nut-hex flange. Check the nuts that are currently on the machine at least once a year. Make sure they are properly tightened and that they are in good condition. Replace them as needed. This OEM part will work for many types of equipment, including lawnmowers, edgers, snowblowers, and lawn tractors. The part will work with many brands, including Ryobi, Poulan, Bolens, Yard-Man, MTD, Yard Machines, and Troy-Bilt.

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 needs fuel to produce the required combustible mixture of air and gas. To get fuel, the carburetor draws the liquid directly from the fuel tank. Any excess fuel will be returned to the tank through the fuel return hose or fuel return line. In addition to providing the path, a fuel line is also responsible for preventing over-pressurization, as well as vapor lock. A fuel return line is constructed from a thick rubber material that is also fuel resistant. However, it may still become brittle and crack due to regular wear and tear. Usually, a broken fuel return hose results in symptoms such as engine misfires, loss of power, carburetor flooding, fuel leaks, and hard starting. A brand-new replacement is available here. This fuel line return is an original part from MTD. It measures 3.78 x 3.78 x 0.016 and is compatible with tillers, leaf blowers, and string trimmers made by Craftsman, Ryobi, Yard Machines, MTD, Bolens, and Yard-Man. Installation will require a screwdriver, cutters, and pliers. This fuel line return is sold individually.

A flange lock nut, also known as a flange lock or a lock nut, is created to be used in various types of lawn and garden equipment. This flange lock nut holds other parts in place and, when properly threaded, will resist loosening. Over time, a flange lock nut may begin to weaken and may become loose or break. If it appears to be broken or weak, a replacement is required. Flange locks can be adjusted and uninstalled after use. When replacement is required, you may need a socket set, screwdriver, hacksaw, and butane torch. The socket wrench will loosen the bolt it is connected to, while the torch is used to heat the lock nut. A socket wrench may remove the nut, but sometimes cutting it with a hacksaw is required. This flange lock nut is a genuine OEM component directly from the manufacturer and comes in an individual unit. It is made of metal, a gold color, and can be found in various areas of lawn equipment. It works with lawnmowers, trimmers, snowblowers, cultivators, tillers, and leaf blowers by Poulan, MTD, Toro, Cub Cadet, Murray, Troy-Bilt, Bolens, Yard Machines, Craftsman, and Yard-Man.

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.

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. Many models claim to come pre-gapped, but they can settle during shipping and should always be re-gapped prior to installation. This is sold as an individual unit. Be sure to wear gloves for hand protection when replacing spark plugs and performing other maintenance.

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.

A bump head knob is a part of a string trimmer. When the trimmer is tapped against the ground or any hard surface, it will let out more line. This component, which is primarily made from rubber, is also responsible for securing the spool to the trimmer head. Over time, a bump knob can break. If it is damaged, the trimmer won't release more lines. It is easy to install a brand-new bump head knob replacement. First, get a screwdriver and unscrew the old bump knob. Grab the replacement and screw it to the trimmer head. Tighten it for a secure fit. This replacement only comes with a bump head knob. It doesn't have other string trimmer replacement parts. For an efficient, compatible part replacement, choose this MTD 791-153066B Bump Head Knob. You can use it with string trimmer models made by MTD, Bolens, Yard-Mad, Yard Machines, Craftsman, Troy-Bilt, and Ryobi. It is a genuine OEM part that is sold individually.

This blade adapter is made to attach a lawn mower cutting blade to the drive shaft of a push mower. Though it is made of sturdy metal and is tightly fastened to the mower's drive, the adapter and blade may wear and loosen over time. This can present a dangerous situation as well as poor cutting performance for the blade. Also, each adapter has a small insert tab that fits into the blade attachment. This tab, called a “key,” is actually a shear pin. Should the blade strike a solid object, the key will sheer off, preventing the blade from coming loose or suffering irreparable damage. The solution to either of these problems is to replace the blade adapter. The blade itself should be closely examined to make sure it fits the new adapter with no wobble or slack. To replace the blade adapter, turn the mower on its side with the air filter on top. Use a ratchet to remove the bolt that attaches the blade and adapter to the drive shaft. Make certain to fit the new adapter key into the keyway on the shaft. Always use a replacement part like this one, that is OEM certified to be identical to the original. This blade adapter is compatible with Ryobi, Yard Machines, Yard Man, Huskee, Cub Cadet, Troy-Bilt, MTD, and Bolens mowers.
