Parts for Craftsman 143941002: Engine 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.

Spark plug covers can help to ensure added protection for the sparkplugs and can make sure that there is no debris getting on them. While the spark plug covers are long-lasting, they will eventually need to be replaced. Over time, they will start to dry, crack, and come apart. When this happens, replace the covers right away. Also replace the spark plugs at the same time. The OEM spark plug cover is sold individually, be sure to get enough to cover all the plugs. The cover can work with many different brands, including Craftsman, Briggs & Stratton, Toro, Cub Cadet, Troy-Bilt, Tecumseh, Lawn-Boy, Snapper, MTD, and Simplicity. The covers can work for many types of machines, including lawnmowers, generators, chippers, log splitters, edgers, pressure washers, tillers, and other small engines.

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.
