Bolens String Trimmer Parts

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.

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.

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.

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.

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.

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.

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.

Installing a brand-new air filter keeps the engine in top running condition. When the machine is in operation, the vacuumed air goes through the air filter. Any dirt or dust is left in the filter media. Over time, the filter will become dirty and can no longer provide the same filtering efficiency as before. If left ignored, the tiny particles could clog the engine and the carburetor. You may experience misfires and no engine start-up. An air filter replacement is cheap and easy to do. Simply remove the air cleaner cover and take out the dirty filter. Insert the new filter into the housing. This replacement will take less than 5 minutes. A screwdriver will be needed.

Mowers are manufactured to last for about 500 hours of running, which breaks down to about 19-20 years for the typical non-commercial user. Commercial mowers, which see a great deal more use, are designed to last for 1000 hours of service, which is about 10 years. To extend the life of a lawn mower to its full potential, there are certain simple preventative routines a user can follow, including annual oil and filter changes. One important routine maintenance ritual for mowers that is often overlooked is changing the air filter, something that should be done at least annually. When the mower chugs, cycles, or simply will not start, the first thing to check is the air filter. When replacing the filter, make sure to use a genuine OEM certified replacement part like this one, which is manufactured according to the specification of the original factory filter. This filter is compatible with Bolens, Yard-Man, Troy-Bilt, Yard Machines, and MTD.

This brand-new, original MTD air filter attaches inside the air filter housing of a string trimmer to block debris and dirt.
