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.

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 is an exhaust gasket designed to fit between the engine exhaust and the exhaust system. It’s designed for use on lawn tractors and is the OEM part for many tractors in the Briggs & Stratton family of brands. When properly installed, it will prevent exhaust leakage. It will also flex enough to allow for parts expanding due to heat. The main symptom of a failed gasket is exhaust leaking from the joint. Gaskets can fail due to a variety of factors. They can dry out, lose flexibility, and crack. They can chafe, losing their heat resistance and drying out prematurely. They can even tear due to excessive engine vibration. In this case, it’s advisable to check your engine mounts to make sure they’re fully secure and tightened. To replace the exhaust gasket, with the engine off, remove the two screws that run through the old gasket. Remove the old gasket and insert the new gasket carefully into place. Screw the exhaust system back together to complete the repair. This is an OEM part sourced directly from the manufacturer and is sold individually.

Flange screws have a flange located near the top of the screw, which helps to distribute the connection force over a larger area to reduce potential damage to the machine. It also allows the screws to be used in oversized or irregular holes, and it helps to ensure they stay in place. This flange screw also has a hex top. Screws can last for a long time. However, they may become corroded or worn over time and need to be replaced. They could also become lost and need a replacement. Without all of the screws in the proper places in a machine, it could vibrate too much, which could render it less effective or unsafe to use. The flange screw is a genuine OEM part that can be used with many types of machines including lawn mowers, snowblowers, tillers, pressure washers, leaf blowers, generators, wood chippers, and other small engines. The screws are compatible with Briggs & Stratton, Craftsman, Toro, Cub Cadet, Murray, Lawn-Boy, Snapper, Simplicity, and MTD.

This oil pump cover is a genuine Midwest Engine part, sold individually. This oil pump cover can be used as a replacement part for lawnmowers, snowblowers, wood chippers, and lawn tractors.

This gasket-rocker cover, also called a valve cover gasket, is used in small engines to create an air-tight seal between the engine and the valve cover. This cover is also made to prevent oil from leaking as it travels throughout the engine. It’s an important component to ensure the cylinder head is protected from the elements and oil doesn’t leave the motor. If this component has failed, replacement is essential to avoid engine failure. Gasket-rocker covers are protected on the bottom and top, but they may experience damage from the sides. Over time, the gasket can crack after becoming brittle, which allows dirt, heat, and debris exposure. This can lead to the cover breaking down and leaking, which may cause reduced engine performance and cosmetic problems. Some signs that replacement is needed include a burning oil smell, a dirty cover, and an engine that runs low on oil. This gasket-rocker cover is a genuine OEM component that is directly from the manufacturer. It’s designed for use with Briggs & Stratton and Toro lawn tractors and small engines. It’s sold individually and can be attached using a torque wrench or a socket set.

This authentic OEM replacement push rod connects to the camshaft on small or medium sized gas-powered lawn tractor engines, and as the camshaft turns, the push rod transfers that motion into the valves. Without a functioning push rod, the valves will not open and the engine will not work. Push rods also act as transferring units that bring oil through the valves and into the camshaft. If these parts start to stick due to poor lubrication, push rods can bend and will no longer work properly. It is also possible, though rare, for a push rod to bend due to general metal fatigue over time. To identify a bent push rod, listen for a ticking sound in the engine and look out for any slipping gears. Accessing the push rods will mean taking apart the camshaft and valves and may require the user's manual. This replacement part is sourced from its original manufacturer and is compatible with Craftsman and Briggs & Stratton lawn tractors. It ships individually.

Combustion engines have a lot of systems and parts that ensure they function properly. They use fuel, air and a spark to get the cylinders going, but they also rely on push rods. These open valves and transfer oil into the cylinder head to ensure proper lubrication. If a push rod is malfunctioning, the engine may not be able to operate or will operate poorly. This replacement push rod will work in many mowers, snowblowers, chippers, and other small engines. It is compatible with Craftsman, Toro, Cub Cadet, Briggs & Stratton, and Lawn Boy machinery. This is an OEM replacement part that may be a bit complex to install, and will require disassembly of various parts of the engine. It ships individually.

Oil filter for most Intek and Vanguard engines and selected L-head twin cylinder engines. It is recommended to replace the oil filter at least once per season.

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.
