Engine Parts

There are multiple uses for the 5/16-18 Hex Screw. It is often used with small gasoline-powered yard equipment such as lawn and garden machines. While hex screws such as these may be used in edgers and snowblowers, the most frequent use this screw is in yard tractors. This variety of screw is commonly used in attaching the various appendages of gas-powered equipment to a central operating platform. In particular, these hex screws are used to secure the engine block of power tools to the frame or housing of the equipment. Once in place, these fasteners have an almost unbreakable strength to them. This is so much so the case that often, in order to detach the engine manifold and repair the inner workings of an engine, the bolts must be chiseled or cut loose. In such cases, it is necessary for the bolts to be replaced during reassembly. Manufacturers insist that genuine OEM replacement parts be used in the rebuilding process. These replacement parts were manufactured to the same exacting specifications used to make the original screws. These OEM screws are compatible with equipment made and sold by Yard-Man, Cub Cadet, Troy-Bilt, Husky, MTD, Bolens, and Yard Machines.

This is a genuine replacement shoulder screw that is compatible with select models of lawn tractors. The shoulder screw has multiple applications in lawn tractors, where it is typically used as some kind of axle for wheels or other components. Over time, this type of screw can become worn from repetitive motion or the threads can start to strip. If the screw fails or is unable to work effectively, it can affect whatever it is responsible for securing or holding, as well. This could result in the entire machine not working until a replacement is made. This is a genuine manufacturer's replacement manufactured by MTD. It is compatible with their lawn tractors as well as those from Yard Machines, Troy-Bilt, Yard Man, Husky, and Cub Cadet. The screw is made of durable metal and is sold as a single unit.

The recoil starter assembly starts the engine by using the grip to pull the rope, which activates the starter pulley and spring, causing the flywheel to rotate and start the engine. Over time, the starter spring can become stretched, causing the rope to seize up or fail to retract. The housing itself could also become damaged. It’s often easiest to replace the entire recoil starter assembly with this OEM model rather than individual components. The installation can be done quickly with a screwdriver and wrench by removing the three bolts that hold the assembly in place. This genuine OEM part is manufactured by MTD. It fits lawn mowers, tillers, log splitters, and other small engines made by MTD, as well as models from Bolens, Yard-Man, Yard Machines, Cub Cadet, Troy-Bilt, and Husky.

This air cleaner cover is designed to house the air filter on larger lawn equipment and other outdoor power tools. There is no aspect of small engine care more necessary than protecting the air that goes into the carburetor and cylinder from yard dust. Nothing is more incapacitating to a small engine than being clogged with dust, pollen, and other particulates that are invariably stirred up during landscaping work. While the air cleaner cover itself is not a moving part and would not seem to be subject to replacement, it is occasionally the case that, through extensive use or accidental contact, the cover becomes unable to shield the air filter within it. In these cases, it is essential to replace the cover with an OEM certified replacement cover that has been manufactured to the same specification as the original. Though replacing the cover itself is quite simple, it probably a very good idea to replace the air filters at the same time. If the cover is in need of replacement, it is quite likely the filters have been exposed to excessive amounts of particulate. This cover can be used on chippers, shredders, log splitter, mowers, and a variety of other small engine/large job equipment. Compatible brands include Troy-Bilt, MTD, Yard-Man, Yard Machines, and Cub Cadet.

This air cleaner housing is used to contain the air filter of a number of small gasoline powered engines. It attaches to the carburetor, holding the air filter in place to prevent particulates from entering the air/fuel mix of the engine. This housing is used on equipment such as walk-behind lawn mowers, log splitters, and other small engines uses. It's fairly rare for the air filter housing to fail. Rather, it's much more likely that the housing will suffer damage from banging against other equipment and obstacles. Additionally, when regularly replacing the air filter, it's a good idea to examine the filter housing for any damage or fitting problems. If the housing is not snug and airtight, dust, grass pieces, and other particulate can enter the carburetor and cause more significant damage. The air cleaner housing is easily accessible and can be removed and replaced. First remove the cover, the filter and prefilter, if present, exposing the bolts that hold the housing to the carburetor. Simply remove the bolts, remove the old housing, and replace it. Reverse the disassembly process, making sure to install a new filter. This housing, which is an OEM genuine replacement part, is compatible with Troy-Bilt, MTD, Cub Cadet, Yard Machines, Bolens, MTD, and Huskee equipment.

This choke bracket is a genuine OEM part sourced directly from the manufacturer for use on snowblowers. The choke control bracket opens or closes the choke plate in the carburetor to help start the engine. The choke should be closed when getting it ready to work. Closing it shuts the air intake and keeps the gas mixture richer, which helps the engine fire up when it is cold. If the choke bracket is rusted or broken and is working, the choke may not work correctly. The engine may not start or may run roughly when it does start. If this happens, the choke bracket should be replaced.Before replacing the choke bracket, remove the spark plug and empty the gas from the snowblower. Wear safety gloves and safety glasses. Locate the choke and remove the screws holding it in place. Remove and discard it and install the new bracket. Use the screws from the original bracket to secure the bracket. Reinstall the fuel and spark plug. This choke bracket is a silver metal part that is sold individually; it does not come with screws or bolts. It is designed for use in snowblowers manufactured by Craftsman and MTD.

This carburetor insulator is a genuine MTD replacement part for appliances with small engines, such as lawn mowers, lawn tractors, lawn trimmers, snowblowers, chipper shredders, tillers, and leaf blowers. The purpose of a carburetor insulator is to keep the heat of the running engine away from the carburetor, which combines the air and fuel that ignites the engine. This keeps the engine from overheating and suffering damage as a result.While there is a chance that a damaged carburetor insulator could prevent the engine from igniting altogether, it is more likely that a damaged carburetor insulator will allow for unmetered air leaks into the carburetor. Unmetered air leaks will cause the engine to take in more fuel, reducing the fuel economy of a small engine appliance. For this reason, if the symptoms align with a diagnosis of a damaged carburetor insulator, it must be individually replaced as soon as possible before using the small engine lawn appliance again.This carburetor insulator is compatible with the following brands: MTD, Cub Cadet, Yard Machines, and Craftsman.

This is a genuine OEM replacement fuel bowl bolt for a snowblower, tiller, or chipper engine. The fuel bowl is a part of the fuel filtration system designed to prevent sediment from clogging up the carburetor. Fuel moves from the fuel tank and passes through the fuel bowl to catch any debris. It is essentially a particle filter. This bolt mounts the fuel bowl in place. The two most likely reasons why a fuel bowl bolt might need replacing are general wear and tear or loss. This bolt is located fairly close to the outside of the engine, making it more susceptible to the elements. Over time, the bolt may corrode and will need replacing. If lost while making a repair to the fuel bowl itself, the fuel bowl bolt will need to be replaced. Use a wrench to make the repair.
