Parts for Craftsman 143941007: Replacement Parts

This piston ring set is specifically designed for use in several types of lawn and garden equipment. The piston rings are the components that maintain the proper fuel compression between the cylinder wall and the piston. These parts are used to fully seal the cylinder, so gas that is generated during ignition doesn't leak out into the opening between the cylinder and piston. If the piston rings have gone bad, the equipment could use up gas much more quickly, have poorer performance than expected, expel white or gray exhaust smoke, or be incapable of accelerating. Piston rings can be damaged through lack of oil, dirt in the cylinder, or stale fuel that creates a build-up. If the piston rings are not working properly, they should be replaced. It's also a good idea to inspect the cylinder for any additional damage.This is a piston ring set that is designed to be used with lawnmowers, snowblowers, and generators manufactured by Briggs & Stratton, Craftsman, Cub Cadet, Toro, Tecumseh, and Simplicity. It is sold as an individual set. This is a genuine OEM replacement part set that is sourced directly from the manufacturer.

This is a genuine replacement exhaust valve. The exhaust valve allows the engine to exhaust as needed. This part also includes the retaining ring, which holds the valve in place as it moves in and out to allow the exhaust to escape from the system. Over time and due to repetitive motion, this valve can break down or become damaged. A replacement will be necessary for proper operation of the machine. If the exhaust valve is faulty, the engine may not run correctly. It may not run at all. A replacement will ensure proper operation of outdoor equipment. Be sure to wear gloves and allow the engine to cool completely before doing any type of engine repairs. This OEM exhaust valve is manufactured by Tecumseh. It meets manufacturer standards for an OEM replacement and is compatible with several machines from the brand. The exhaust valve is sold as an individual part and does not include any additional parts or hardware. Those must be purchased separately.

This screw is a genuine Tecumseh replacement part for several different kinds of small engines, including lawn tractors, lawn mowers, snowblowers, woodchippers, and generators. A screw's function is to tightly join parts together through rotation of the screw. This prevents the materials from loosening and unfastening over time. A screw might be misplaced or lost the screw altogether, since it is a small object that can easily fall out of its place and disappear if loosened. Other reasons to replace a screw can include the gradual deterioration, erosion, cracking, or piercing over time; this kind of damage can be attributed to general overuse or exposure to the elements. If a screw is subject to any of this kind of damage, it is best to replace it before using the appliance at hand, as the pieces must continue to be held together by the screw. Remember to always wear gloves when handling, repairing, and operating outdoor equipment. This screw is compatible with the brands Tecumseh, Craftsman, Toro, and Briggs and Stratton. This part sold individually.

This breather gasket is made of durable but flexible plastic, designed to seal the cylinder block and the breather body. A breather is a pipe that enables internal combustion in the engine to properly vent any crankcase pressure out of the engine. It is essentially a venting pipe or system and ensures that the engine's piston rings seal tighter against the cylinder walls (however many there are in that engine). When this gasket dries out, that pressure and seal cannot be created effectively and the engine may malfunction. Replacing the breather gasket means using a wrench to disassemble the breather, clean the surfaces, remove the original gasket, and use this authentic replacement part before reassembling This is an OEM replacement part designed for Toro, Tecumseh, Lawn-Boy, MTD, and Husqvarna equipment, including snowblowers and other small engine systems. This item ships individually.

This is a breather designed to be used on various types of lawn and garden equipment. The breather is an essential part that is responsible for venting out excess air from the engine's crankcase. If the equipment's engine isn't working as well as it used to, it could be related to a broken or damaged breather. In this situation, the breather will need to be replaced.Replacing the breather will require a socket set, a nut driver, a Phillips head screwdriver, and a set of pliers. Inspecting the breather or making a replacement starts with removing the equipment's muffler. This will give access to the original breather for visual inspection. If it has damage, it should be removed. The new part can be replaced before reassembling the tool.This breather is a genuine OEM replacement part that is sourced directly from the manufacturer. It is sold as an individual component. The breather is designed to fit onto lawnmowers, snowblowers, tillers, generators, and wood chippers manufactured by Briggs & Stratton, Craftsman, Toro, Cub Cadet, Tecumseh, Lawn-Boy, MTD, and Simplicity.

This intake manifold allows an engine to get the air it needs in order to run properly. Any engine runs on three things - air mixed fuel, the sparks, and combustion. It is the intake manifold that delivers the air to all of the cylinders and guarantees function. This gasket is used to replace a pre-existing intake manifold gasket that has dried out or has failed to keep the intake manifold properly sealed to the engine. This may allow air leaks or uneven air pressure in the cylinders, affecting how well the engine runs. Any gasket may wear out with time and use, and replacing the a failed intake manifold gasket with this OEM part is one way to ensure that the engine is again running at optimal levels. The repair requires wrenches, socket sets, and the appropriate components for the engine in question. This is a gasket for an intake manifold on an array of lawnmowers, lawn tractors, and snowblowers made by Tecumseh, Toro, MTD, and Lawn-Boy, and others. This high-quality intake gasket ships individually and is made of composite materials.

This air filter is manufactured by Tecumseh and is an OEM replacement part for select compatible engines on lawn and garden equipment. The air filter system in an engine is designed to help ensure maximum airflow and remove dirt and debris from the air as it is entering the carburetor and the engine. This filter is made of durable plastic and composite paper materials and includes metal screening to help catch more debris and ensure the filter holds its shape. The air filter will collect particles of dirt and debris, and over time it can become clogged from regular use. Air filters should be replaced regularly as a part of routine maintenance, and this replacement part will do the job for models that take the filter. Always disconnect the spark plug when performing maintenance. Replace air filters annually or as needed and choose genuine OEM parts like this filter for the best results. This OEM filter can be used with several different engines made by Tecumseh, including 7, 8, and 10 HP models. This part may be used on generators, wood chippers, or other small engines from Briggs & Stratton, Craftsman, Tecumseh, MTD, and Simplicity.

This durable metal screw is used in various types of lawn and garden equipment. A screw can be used on its own to attached two components together. It can also be used with a nut when there is a pre-drilled, threaded hole for it to go in. If a nut is being used, it should have the same finish and use the same threading as the screw does.This screw is typically used to fasten a fuel tank to a tank mounting bracket on the engine. It can be damaged in many ways and will need to be replaced if it has failed. Extreme temperatures, excess stress, and corrosion can all damage or break the screw. Do a visual inspection of the part to see if it has any wear and tear or has broken. If it has, it can be replaced using a screwdriver.This screw is designed to be used with lawnmowers, snowblowers, tillers, pressure washers, edgers, generators, and wood chippers manufactured by Briggs & Stratton, Craftsman, Cub Cadet, Toro, Tecumseh, Lawn-Boy, Snapper, Simplicity, and MTD. It is a genuine OEM replacement part that is sourced directly from the manufacturer. It is sold as an individual screw.
