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 flanged lock nut. It’s designed to apply tension, typically on a joint that needs to have a certain amount of flex. As such, it’s mostly used on snowblower chutes and lawnmower handles. They can remain in place, but with a forgiving connection that can take a beating. The nut size is 3/8, with a thread size of 16. A lock nut will generally last for many years. However, the silicone ring inside will wear down if it’s frequently tightened and loosened. It needs to be replaced when it will no longer reliably remain in place. Generally, this begins as a symptom of slight slippage and worsens as time goes on. Thankfully, whether it’s being used on a snowblower or a lawnmower, this nut is generally straightforward to access. Simply unscrew the old nut, then screw the new nut on until it’s nice and tight. Our flanged lock nuts are genuine OEM MTD nuts, and they are sold individually.

• Use the correct nut driver or socket to avoid rounding the head
• Replace one fastener at a time to maintain alignment; do not overtighten
• Match screw type/length to the original location as specified by the 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. 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 lawnmower’s fuel line or a fuel hose brings the fuel from the tank to the carburetor. It is made of durable translucent plastic material. When pushing the primer bulb, the gas from the tank will travel through the fuel line and to the carburetor. Once there is enough fuel, any excess will go to the return line and into the tank. Fuel lines are made from sturdy rubber or plastic. Over time the fuel line can crack and begin to leak. There are few symptoms of a broken fuel hose. One of the easiest ways to tell is if the hose has visible exterior cracks. Other warning signs include fuel smell and fuel leaks. Installing a new fuel line is easy and doesn't require any tools. Detach the old fuel pipe and insert the new replacement. This MTD 791-682039 Fuel Line Assembly OEM Replacement is an original four fuel line assembly compatible with Yard Machines, Yard-man, Ryobi, and Bolens. This replacement fuel line does not include the primer bulb and fuel return line. You need to purchase these parts separately.

This is a genuine replacement bolt that is designed specifically for use on select lawn tractors. This tractor bolt is a specialty piece of hardware designed for use on the steering segment gear. This screw holds the gear in place and is exposed to constant vibrations and repetitive motion as a result. Over time, that can result in damage, wear, or even total breakage of the bolt and require a replacement. If the bolt isn't functional or is missing, the steering segment gear will not be secured and that can lead to further damage if left unattended. Using a genuine replacement part like this will guarantee an exact fit for compatible models. This genuine OEM gear bolt is manufactured by MTD. It is compatible with lawn and garden equipment from RYOBI, HUSKEE, Troy-Bilt, Bolens, Yard Machines, Yard Man, and Cub Cadet, along with select models from MTD. The bolt works for more than 100 compatible models. It is made of durable metal and sold as an individual unit. A wrench or socket will be required to replace this part. Always wear gloves when performing repairs on lawn and garden equipment and allow the engine to cool before doing any work.

This oil seal is found in many different lawn and garden machines on the gearbox, including garden tillers. It is a genuine OEM replacement part sourced directly from the manufacturer. It is designed to prevent water, dirt, and other pollutants from getting inside the gearbox and causing damage or poor performance. The seal also ensures that oil doesn't leak from equipment. Normal wear and tear reduces the functionality of the seals and reduces engine performance as well as causing oil leaks. The oil seal should be inspected and replaced as part of routine maintenance. This repair takes approximately one hour. A socket set and seal pull are needed. Remove the spark plug wire before working on the equipment. Place tiller on a flat surface and jack up the rear tines. Take the rear tines, wheels, and tires off the machine. Clean the shafts to remove dirt and debris buildup. Remove the damaged seals and clean the part before installing new seals. Install the new oil seal and fill the gearbox with gear lube. Reinstall the spark plug. This is a heavy-duty metal and rubber oil seal sold as an individual unit. It is compatible with tillers manufactured by Troy-Bilt, MTD, Yard Machine, and Craftsman.

This screw is used on a variety of lawn and garden equipment from many manufacturers. This hex screw is a large bolt that has a six-sided head that can be used to fasten metal to wood or wood to wood. This type of screw is unique from traditional screws because the bolt head needs to be held with a socket while a second wrench is used to tighten or loosen the part. The bolts have a smooth shank and small threads. These screws can break or become damaged and no longer do their job. When that happens, they will need to be replaced. A hex key wrench can be placed into the slot of the screw and turned counterclockwise to loosen up the bolt. The replacement hex screw can then be placed in the original hole to adhere parts together on lawn equipment. This is a genuine replacement OEM screw that is commonly used on Craftsman, Toro, Murray, MTD, Yard Machines, Troy-Bilt, Bolens, Yard-Man, MasterCut, Cub Cadet, and Huskee lawn mowers, log splitters, snowblowers, chainsaws, tillers, and string trimmers.
