The largest factor hampering the engine efficiency of lawn mowers is the air in the air/fuel mix. This Briggs & Stratton pre-cleaner filter is a flat device that sits inside the air filter housing and purifies the air of contaminants and particulates before it even reaches the air filter. This improves the lifespan of the air filter and improves the efficiency of the engine. The pre-cleaner, because it is highly effective at removing dust and other contaminants from the air, will eventually become full of particulate. At that point, the user may notice difficulty in getting the mower to perform. To replace the pre-cleaner, remove the outer air filter cover snd locate the old pre-cleaner just inside. Remove the old filter and replace it with the new one. Attach the top cover. This is an OEM certified replacement part that was built to the exacting standard of the original equipment of the tractor. Although it was manufactured intentionally for the Toro lawn tractor, the filter is also compatible with several other brands, including Simplicity and Briggs & Stratton.

This oil seal is a genuine OEM replacement part designed for use on a wide variety of small gas-powered appliance engines. Although small, an oil seal is an important part of the oil cylinder assembly as it prevents oil from leaking into other parts of the engine. If oil begins to leak into the engine, it can corrode other parts or even pose a fire hazard. Therefore, it's important that the oil cylinder is tightly sealed to prevent any damage to the engine. Seals can wear out over time, especially if exposed to heat. Heat will cause the seal to shrink, effectively unsealing the oil cylinder. Before making this repair, be sure to drain the oil cylinder of any oil and be prepared for an involved replacement process. This part is compatible with Toro, Murray, and Briggs & Stratton appliances and is sourced from the original manufacturer. It ship individually of other hardware.

This is the rocker cover gasket, which seals the cylinder head on small engines so that the engine doesn’t develop leaks. Periodically, a gasket may deteriorate with heavy use. To maintain good engine performance, the rocker cover gasket needs to be replaced with an OEM certified replacement. This type of gasket is most often found on lawn tractors. Replacing the original gasket with the new one is a simple and straightforward process. There are four bolts holding the valve cover in place. Simply remove them and the old gasket, which will likely have to be scraped to get it completely off the cylinder head. Place the new gasket exactly over the metal frame of the cylinder head—it should fit perfectly. Hold it in place with a small amount of RTV, a silicon sealer that is impermeable to oil and gasoline. Replace and tighten the four valve cover bolts. This part is made by Genuine Midwest Engine. This part is used in Briggs & Stratton engines and also used by Toro and Vanguard. This is an OEM part. It's also sold individually.

This cylinder head gasket is a genuine replacement part for select small engines. The cylinder head gasket is installed between the cylinder head and the engine block. It is responsible for creating a seal for the internal combustion engine to work properly and to help keep the oil and coolant separate as they travel between the cylinder head and the engine block. Gaskets are considered a maintenance part because their exposure to high heat and pressure cause wear, warping, and other damage over time. When a gasket is damaged, the seal is affected. Air could escape or the oil and coolant could mix, which would both produce bad results for the engine. This genuine OEM cylinder head gasket replacement is manufactured to exact standards by Briggs & Stratton. This part is compatible with select engines found in lawn and garden machines manufactured by Briggs & Stratton and Toro. The gasket is sold as an individual part and does not include any hardware or additional components. Be sure to allow the engine to cool and wear gloves when replacing gaskets. It is a good idea to replace gaskets when performing other engine repairs to ensure a proper seal when putting the engine back together.

A pinion gear is a small cylindrical component that is integral with a rack and pinion mechanism. Together with the rack, its primary function is to transform rotational movement into linear motion. Machines like lawnmowers and lawn tractors have a rack and pinion system. When the steering wheel of a tractor is moved, the gear will rotate, which engages the rack. Although this component is exceptionally durable, it is still subject to wear and tear. Some symptoms of a bad rack and gear mechanism include a loose or tight steering wheel and a grinding noise. Performing a do-it-yourself rack and gear replacement is possible and takes only 30 to 45 minutes. If the rack is in good condition, but the gear is not, omly a pinion gear replacement may be needed.

This genuine OEM replacement part is a spark plug terminal for a wide variety of small combustion engines. In a combustion engine, the spark plug generates a small electrical charge that creates enough power to start up the ignition and engage combustion. The plug connects to the ignition through the terminal. Spark plugs generate and then pass a small electrical current through to the ignition. Usually, the main issue with spark plugs is that this current hyper-extends and ends up frying the spark plug. However, if the terminal is damaged, the charge will not pass into the ignitor, and the engine will not turn. If the spark plug can carry a charge but the engine still won't turn, it's likely the terminal that needs replacing. This is an easy repair because the terminal should just snap on and off. If stuck, a pair of needle-nose pliers should make it easier. This high-quality replacement part is compatible with engines from Murray, Toro, Lawn Boy, and Briggs & Stratton. It is sourced from the original manufacturer and ships individually.

This is a rotating screen that protects the lawnmower engine from debris and dirt that could damage the engine. It is an authentic OEM replacement part sourced directly from the manufacturer for use on a variety of lawnmowers. If the screen becomes damaged or broken, dirt and debris could damage the engine or other critical parts. Without the screen, small animals and insects, like little birds and bees, could get inside the engine cavity and make nests. This could be detrimental to the engine and to the animal. During the inspection, if the screen is found to be damaged, it should be removed and replaced. A Torx driver is needed to remove the screen. Wear work gloves and make sure the spark plug has been removed from the lawnmower. Remove the Torx screws and set them aside for use on the new rotating screen. After removing the screws, the blower housing has to be removed in order to remove the screen. After the screen is removed, clean the engine cavity with a blower to remove any dirt or debris. Install the new cover, then reinstall the blower housing and spark plug.This rotating screen is made of durable black plastic and is sold as an individual part. It is designed for use on lawnmowers manufactured by Toro, Briggs & Stratton, MTD, and Craftsman.

This replacement oil drain plug is a genuine OEM part for a lawn tractor or generator engine. The oil drain plug connects to the base of the oil tank and allows the appliance owner to drain used oil and replace it with new, clean oil. The oil drain plug is threaded to screw into the oil tank and prevent it from popping out of place while the appliance is in use. The most likely reason to replace an oil drain plug is if the old plug's threading has become stripped and no longer holds onto the oil tank. Alternatively, the plug is quite small and could easily be misplaced during an oil change. If lost, oil will leak from the engine, causing parts to overheat. Fortunately, replacing a lost or damaged oil drain plug is simple and only requires screwing a new plug into place. This replacement plug is a high-quality part that fits Craftsman and Murray products. It comes sourced from its original manufacturer and ships individually, without any additional hardware.
