Parts for Briggs & Stratton 9S502-1042-B1: Cylinder / Gasket Sets Parts

This is a genuine OEM bushing/seal kit that is manufactured for use on a selection of Briggs and Stratton engines found on outdoor power equipment. The seal and bushing are responsible for providing a sealed connection within the engine. They are exposed to constant vibrations, pressure, and high temperatures, which can cause them to wear down over time. Seals can also become brittle and damaged with age, resulting in the need for replacement. It's best to purchase the kit and replace both parts at once with this OEM set from Briggs and Stratton. This OEM seal and bushing kit is manufactured for use in Briggs and Stratton engines found in snow throwers, lawn mowers, and leaf blower/vacuum models produced by the brand. It is also compatible with select models from Toro. The bushing and seal are sold as a kit, which includes one seal and one metal bushing. No other hardware or accessories are included. Any other needed hardware will require an additional purchase. It is important to wear gloves when performing repairs on outdoor equipment and make sure that the right tools are used for the job.

This oil seal is a common part engineered to work in engines that power generators, vacuum cleaners, snowblowers, leaf blowers, mowers, and other small engine applications. The seal sits between the crankcase and the crankshaft. It is designed as a barrier to prevent oil leakage and to stop contaminants from leaving the crankcase. When the gasoline engine exhibits diminished power, and especially if it begins to emit oily gray or bluish smoke, there is a good chance the oil seal needs to be replaced. In order to replace the faulty seal, begin by removing the starter housing and taking off the nut that holds the starter wheel to the main shaft. The user will find the old seal on this shaft. Remove it and install the new seal, pushing it into place with the edges of a socket, then tapping it securely into place with a hammer. When choosing a replacement seal, remember to use an OEM genuine replacement part that is guaranteed to match the specs for the original part. This will ensure a quality match and long replacement life. This seal is compatible with Toro, Lawn-Boy, and Briggs & Stratton engines.

This is a cylinder head gasket used on Briggs & Stratton small gasoline engines to replace the original gasket that sits between the cylinder, where the engine's combustion takes place, and the head, the top of the engine manifold. Typically the head gasket lasts for many years. With continued use, particularly if the mower or other small engine is used commercially, the user may notice leaking oil or heavy, white smoke coming from the mower when it runs. This is often a sign that the head gasket has been compromised and needs to be replaced. This gasket fits most Briggs & Stratton engines and is a genuine OEM replacement part guaranteed to be identical to the worn gasket that is being replaced. In order to replace the gasket, begin by removing the head bolts and the smaller screws that secure the pull cover; remove the head; scrape the remaining parts of the old gasket from the top of the cylinder head; sand down both the head and the cylinder surfaces and finish with paint thinner; make certain the new gasket seats precisely where the original was, then reverse the disassembly process. Make certain not to over tighten the screw when reassembling the mower. This gasket will fit most models of Briggs & Stratton small engines on machines such as lawn mowers, tillers, pressure washers, and edgers.

This replacement crankcase gasket is a genuine OEM part designed for a range of different small gas-powered lawn appliance engines. It is commonly found in tillers and lawn mowers. The crankcase is a housing for the crankshaft, which receives reciprocal motion from the pistons and transforms it into rotation motion. This gasket helps seal the crankcase to create an airtight chamber and prevent oil from leaking so that the crankshaft can operate smoothly. As the engine runs, it produces a lot of heat and gases that eventually wear on gaskets. Over time, all of this stress can cause a gasket to degrade and break its seal. If this happens, oil will leak from the crankcase, the engine will easily overheat, and greyish white smoke will visibly blow out from the exhaust pipe. Replacing a crankcase gasket will require disassembling much of the engine, as it is an internal part, so we recommend following the owner's manual or consulting the manufacturer's website for instructions. This part is a high-quality replacement gasket manufactured to exactly match the specifications of the original part. It is compatible with Toro and Briggs & Stratton engines and ships individually.

This screw, manufactured by Briggs & Stratton, has multiple uses in small and medium sized gasoline powered engines, including generators, leaf blowers, lawn mowers, log splitters, chippers, tillers, pressure washers, and vacuums. Bolts of this design are used to secure engines and accessories to the body of the power tool. Manufactured with a smooth nozzle, these bolts are capable of withstanding four times the resistance of a regular hex bolt. For this reason, they are often used to secure the housing of moving parts, such as the cylinder head. Periodically, the wear and tear experienced by any engine will result in interior pieces needing to be replaced. In such cases it always a good idea to also replace the hardware that secures the various parts of the device together. Flange bolts and nuts should be replaced with genuine OEM parts such as this one, which is manufactured to meet the same specifications as the original. Occasionally, the high heat of the engine, coupled with extensive use, can cause a hex bolt such as this to freeze up. In such a case, a machinist is necessary to drill out the original bolt and retap the hole so the bolt can be used. This screw is compatible with equipment manufactured by Briggs & Stratton, Simplicity, MTD, Craftsman, Lawn Boy, Toro, Cub Cadet, and Murray.

This oil seal is used in a range of small engines, such as those found in lawnmowers. It ensures the oil stays inside of the crankcase and seals the shaft to provide the correct engine pressure. The seal also reduces the risk of leaks.Over time, oil seals will wear out and need to be replaced. They could crack, break, or shrink. This could result in leaks, and engine performance could be affected. Whenever servicing the case, it is recommended to check and replace the oil seals. Both seals and gaskets should be inspected as part of routine maintenance. To perform the replacement, pliers, a wrench set, and a screwdriver will be needed. The engine needs to be cool and the oil needs to be drained before making the replacement.The oil seal is made from durable, high-quality rubber. This is a genuine OEM replacement part that can be used in a wide range of small engines and lawn mowers from Briggs & Stratton and Toro. The oil seal is sold individually.

This air cleaner gasket is a genuine replacement that is designed for select models of 3-5 HP small engines from Briggs & Stratton. The air cleaner gasket is designed to fit between the air cleaner and the carburetor assembly. This helps to create a seal between the two components and ensure that air does not leak out of the engine to provide the appropriate pressure. Gaskets are exposed to a lot of heat and pressure, along with constant vibrations, which can cause them to become frail or brittle over time. Replacing them is usually considered a part of routine maintenance and OEM parts should always be used. This genuine OEM air cleaner gasket is manufactured to exact standards and can be used on select engines from Briggs & Stratton and Toro. The engines are typically found on equipment like blowers, lawn mowers, generators, and other small lawn and garden machines. This gasket is sold as a single unit and does not include additional components or hardware. To replace the gasket, be sure to have the appropriate tools and a cool engine for best results. Never perform work when the engine is hot and always wear gloves to protect the hands.

A spark plug is used to create a spark to ignite the fuel in the engine while the combustion process is occurring. As time goes on, the spark plug may go bad or become worn, which can prevent the engine from firing correctly. A multimeter can be used to test a spark plug for continuity. It’s also important to visually inspect the plug for corrosion, cracks, or damage. If continuity is not present or the spark plug is damaged, it will need to be replaced. This can be done by removing the engine cover and taking off the spark plug boot. At this point, a socket can be used to loosen the spark plug enough to remove it. The new replacement spark plug can be installed before replacing the boot and covering the engine. This is a genuine OEM replacement part by Briggs & Stratton. It is also compatible with lawnmowers, snowblowers, pressure washers, lawn tractors, generators, leaf blowers, and tillers by Husqvarna, Toro, MTD, Simplicity, Murray, Cub Cadet, and Lawn-Boy. It is sold individually.

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.
