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 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 a replacement rocker arm adjuster that is specifically designed for use in select lawn mower engines. The rocker arm adjuster attaches to the rocker arm, which is responsible for opening and closing the valves on the engine responsible for injecting fuel and air. By doing this, it impacts the horsepower and performance of the engine. Over time, rocker arm adjusters can become lost or damaged. If they are not functional or are missing, the rocker arm will not be able to open and close the valves appropriately and the engine may not function at all.

This genuine Midwest Engine valve cap protects the internal workings of the small engine by keeping dirt, debris, pebbles, and any other small material picked up by the appliance out of the engine. The valve cap of a small engine outdoor appliance might have to be replaced if it suffers damage or if it is simply lost or misplaced, which could allow dirt and debris swept up into the air by the appliance to enter the infrastructure of the machinery and cause internal damage. Before more severe damage occurs, it is best to remove and replace the damaged valve cap. This replacement should be done before using the outdoor appliance again, as to not run the risk of further damage. Remember to always wear gloves when handling, repairing, and operating outdoor equipment. This valve cap is compatible with the following brands: Midwest Engine, Briggs & Stratton, Toro, Simplicity, Lawn-Boy, MTD, Craftsman, and Cub Cadet.

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.

Fix oil leaks around your dipstick with this engine O-ring seal. Prevents debris from entering oil system. Simple install stops leaks and protects motor.

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.

This rocker arm is a genuine Midwest Engine part. A rocker arm is a vital part of an internal combustion engine that controls the intake and exhaust valves in order to direct power from the engine to the wheels, setting the appliance, such as a lawn tractor, wood-chipper, snowblower, or lawn mower in motion. Natural wear and tear from extended use over a long period of time can cause an internal combustion engine to malfunction or fall into disrepair. The longer a rocker arm is in use without replacement, the more likely it is to be subject to damage. This will require a replacement rocker arm. Signs of weakening infrastructure for which the rocker arm might be responsible can include unexplained clicking noises, stalling engines, lit-up check engine lights, and clear visual signs of deterioration on or around the rocker arm itself. Always wear gloves when handling, repairing, and operating outdoor equipment.This rocker arm replacement part works with engines, lawn tractors, wood chippers, snowblowers, and lawn mowers from brands Briggs and Stratton, Toro, Cub Cadet, Lawn Boy, Craftsman, MTD, and Simplicity.
