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.

When the fuel in a small, gasoline-powered engine moves up the fuel line, it must be mixed perfectly with air and together burn in just the right mixture and amount in order for engines to function properly. Because too much gas might be coming into the carburetor or because there might be a need for more gasoline than can readily move up the fuel line, the carburetor has a small device called the float bowl. The float bowl has a ready supply of gasoline for use as needed by the carburetor. To keep the gasoline in check while all this is happening, a device called the float bowl gasket keeps all the elements separate. With use and age, sometimes these gaskets crack or grow brittle and must be replaced. This causes air to leak into the mix and the engine will not operate smoothly. Replace this gasket with a genuine OEM replacement part like this one, manufactured to be exactly like the factory original that is being replaced. This part is compatible with engines sold by Toro, Simplicity, MTD, Briggs & Stratton, and Cub Cadet. Part sold individually.

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.

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. It can be used as a replacement part for the small engines of outdoor appliances such as lawn tractors, lawn tractors, snowblowers, wood chippers, leaf blowers, tillers, and edgers.
