This authentic OEM replacement cylinder head gasket fits a variety of different lawn tractors. The cylinder head, or more commonly just “head”, is an integral part of the combustion chamber. The head sits at the top of the cylinders and closes them off to create a chamber. The head usually has openings that connect to the exhaust and airflow. However, it is important that neither air nor exhaust leak in or out of these connections. The head uses several of these gaskets to prevent that from happening. The cylinder head makes up a part of the combustion chamber and, as such, gets very hot. Over a lifetime of use, a cylinder head gasket can overheat and warp. When this happens, it will no longer seal the cylinder head and must be replaced. Replacing a cylinder head gasket requires disassembling much of the engine, so follow the user's manual closely while making this repair. This part is compatible with Toro and Briggs & Stratton lawn tractors and comes sourced from its original manufacturer. This part does not include any additional hardware.

The crankcase is a metal case over the crankshaft of an engine. It is essential to the operation of the engine as it shields the crankshaft and rods from any debris. It also ensures the pressurization of the chamber and helps to keep pistons and oil moving properly. The crankshaft gasket is part of what keeps the seal and allows the engine to function. It can wear with time or even become dry and cracked. It will cause oil leakage, smoke, and even engine failure. This is a genuine OEM crankcase gasket for lawnmowers, lawn tractors, and small engines produced by Toro, Cub Cadet, MTD, Briggs & Stratton, and Simplicity. It comes as an individual component.

This is a genuine replacement for the camshaft in select Briggs & Stratton engines. The camshaft is found in the crankcase assembly and is designed to help turn the crankshaft to power the engine. This part helps crank the engine and so it is exposed to constant wear and repetitive motion, which can cause it to deteriorate with regular use. It can also break or become damaged due to impact. Without a properly functioning camshaft, the engine will not be able to function, so a failed part must be replaced. This genuine OEM camshaft is manufactured to specific standards and designed to fit select Briggs & Stratton and Toro equipment that has compatible engines. This camshaft includes the part itself along with two metal tappet valves, and is sold as an individual unit. This part is made of durable metal. Other components are sold separately. Allow the engine to cool completely before performing any repairs and always wear gloves to provide hand protection when working on lawn and garden equipment and engines.

This genuine OEM replacement intake manifold gasket for a small gas-powered lawn appliance motor acts as a seal between two engine components, like any other gasket. However, the intake manifold gasket is one of the most necessary gaskets because it is responsible for sealing the engine vacuum and coolant. Intake manifold gaskets can be damaged because of their location in the engine. If the engine has been running hot for a while, the metal can expand and crush the gasket, causing it to fail. If this happens, the engine will begin overheating, as coolant can no longer reach the areas where it is needed. Replacing an intake manifold gasket will mean removing the air filter and its housing, the oil drain tube, blower housing, breather tube, and carburetor. Making this repair requires a set of socket wrenches and screwdrivers. This part is compatible with a wide range of mowers, chippers, and blowers from Briggs & Stratton, Toro, Cub Cadet, MTD, Simplicity, and Lawn Boy. It is sourced from the original manufacturer and ships individually.

This is an O-ring seal that can be used in many types of engines for lawn and garden equipment. It is responsible for sealing the connection between the cylinder head assembly and the intake manifold. The sealing process prevents dirt and debris from moving throughout the equipment and getting into the motor. As time passes, the O-ring seal can shrink, causing oil or air leaks and decreasing engine performance.When the O-ring is damaged, clogged, worn, or broken, it will need to be cleaned or replaced before using the lawn equipment again. The damaged or broken O-ring seal can be removed using a flat head screwdriver. After it has been removed, the replacement component can be installed in the same place. Make sure that the O-ring seal is properly seated to avoid additional leaks. Reassemble the parts before using the tool. This is a genuine OEM replacement part that is sourced directly from the manufacturer. It is sold individually. It is used in lawnmowers, lawn tractors, snowblowers, and wood chippers manufactured by Simplicity, MTD, Lawn-Boy, Cub Cadet, Toro, and Briggs & Stratton.

This O-ring seal is used in all sorts of lawn and garden equipment as a seal for the oil dipstick. It helps seal the system from debris and dirt that could otherwise reach the oil and end up in the motor. Over time, an O-ring will start to shrink, which can result in air and oil leaks and a poorly performing engine. If the O-ring has pits, blisters, or pocks on the surface, it will also need to be replaced.If an O-ring seal is worn, damaged, or clogged, it should be cleaned or replaced before the equipment that houses it is used again. A flat head screwdriver can be used to remove the damaged O-ring. Once the old one has been removed, a new one can be placed into the same position before using the tool.This O-ring seal is designed for lawnmowers, snowblowers, tillers, wood chippers, pressure washers, generators, and leaf blowers. It is compatible with equipment from Simplicity, Briggs & Stratton, MTD, Craftsman, Snapper, Toro, Lawn-Boy, and Cub Cadet. The seal is a genuine OEM replacement part directly sourced from the manufacturer. It comes with a single seal.

This replacement valve seal is a genuine OEM part for a lawn tractor or mower. The valve stem is a type of valve that transfers oil into the cylinder and then immediately reseals due to the pressure in the chamber. However, if the seal is damaged, it will not close and oil will leak into the cylinder. If this happens, the cylinder head may become overly lubricated and not run well. This seal helps prevent that from happening. It fastens to the intake valve and valve stem keeper. Seals will naturally wear out over time due to stress and exposure to corrosive oxidizing agents in an engine. When this happens, the valve will leak oil. To test if the valve seal is compromised, look for whitish-grey smoke that indicates burning oil and also measure to see how much oil the engine is consuming. If the seal is breached, use a screwdriver and socket wrench set to change out the part. This top of the line replacement valve seal is compatible with Briggs & Stratton, Toro, and Lawn Boy lawn tractors. It is sourced from the original manufacturer and ships individually.
