Murray 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.

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 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.

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.

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.
