Parts for Briggs & Stratton 422447-4159-E1: Crankcase Cover / Sump, Cylinder / Head Parts

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 genuine OEM breather gasket creates a tight seal in the breather, allowing the exhaust gases to flow and escape properly and regulating the pressure in lawn and garden machine engines. It also helps distribute the pressure evenly over the breather and the valves. Over time, this part can become brittle like all gaskets, as it is exposed to constant pressure and high heat. This can cause it to crack, break, or even create a leaky seal. In any case, a full replacement will be necessary and this genuine OEM replacement gasket can provide the solution. One gasket is included and all other parts and hardware are sold separately. Always allow the engine to cool before replacing gaskets or performing other repairs. Use the correct tools for replacement to ensure that the gasket is not damaged in the process. This breather gasket is manufactured to exact standards by Briggs & Stratton. It has applications on more than 100 compatible machines made by this brand, Toro, and Murray, including lawn tractors and generators. This part is a composite piece that is made of premium materials and sold individually.

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.

This is an authentic oil seal that is designed for use with select models of small engines. This specific oil seal is found on the power take-off side, or PTO side, of the engine. It provides a strong seal for the crankcase to prevent leaks and ensure optimal engine pressure. Over time this seal will wear out and may break, crack, or shrink. This will affect its ability to provide a proper seal. That can impact engine performance, cause fluid leaks, and more. Seals and gaskets are always considered a part of routine maintenance and they should be inspected during other repairs to ensure that everything is functioning properly. If not, this part can provide a replacement. This genuine OEM oil seal is manufactured by Briggs & Stratton and designed for use in more than 150 engines that are made by the brand. The seal can be used in equipment manufactured by Toro and Murray, as well, including generators, mowers, lawn tractors, snowblowers, and other small equipment. This oil seal is made of durable rubber material and sold as an individual unit. A screwdriver, pliers, and wrench set will be required to perform this replacement. Be sure to drain the oil and only work once the engine is cool.

The spark plug boot is a rubber piece that is responsible for connecting the spark plug to the spark plug wires and completing the connection. Spark plugs are necessary to create the engine spark that will start the motor in lawn equipment and other small engines. The boot holds the terminal and keeps everything protected from the elements and insulated so that it continues to work correctly. If the spark plug connection seems weak or if the existing boot is damaged, this replacement could provide the solution. This durable rubber boot will insulate the spark plugs and help any small engine run better. This spark plug boot replacement can be used with a number of Briggs & Stratton engines and is compatible with hundreds of different machines from Toro, Lawn-Boy, and Briggs & Stratton. This boot replacement is sold individually as a single piece and does not include the terminal or any other housing or materials.
