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 genuine replacement crankcase gasket creates an airtight seal on the crankcase so that oil and air do not leak out of the engine when it is running. Over time, this gasket is exposed to extreme pressure and high heat and will naturally deteriorate. It could become faulty and create leaks or it could break entirely. In either case, a full replacement of the gasket is the only solution. This OEM part can provide an exact fit for compatible lawn and garden equipment engines. This genuine crankcase gasket is manufactured to strict standards by Briggs & Stratton and is compatible with select engines on lawn mowers and generators from Briggs & Stratton, Lawn Boy, and Toro. This gasket is made of durable composite material and it is sold as an individual unit. Other gaskets, hardware, or related parts are all sold separately. The repair can be done with just a wrench, but be sure to allow the engine to cool entirely before beginning any repairs. Always wear gloves and disengage the spark plug for safety when performing engine work.

This authentic replacement oil seal is for use with a range of small engines. The oil seal is the lower seal that is located in the engine's sump. The seal is made to ensure that there are no oil leaks that could cause issues with the performance of the engine. If the seal is not working properly, it could result in leaks, and the machine may not have enough oil to function properly. Lack of oil can also cause serious issues with the engine. The oil seal is prone to wearing out over time. The seal can become worn and it can start to deteriorate the longer it is used. Owners should make it a point to replace the oil seals whenever they are changing their oil, oil filter, and gaskets. The oil seal is a genuine OEM replacement part, and it is sold individually. The oil seal is compatible with more than 150 different models of machine. This includes models of lawnmower, snowblowers, pressure washer, leaf blowers, generator, wood chipper, and other small engines. Compatible brands include Briggs & Stratton, Craftsman, Toro, Lawn-Boy, and Simplicity.

The flywheel key is the component on outdoor equipment that keeps the flywheel connected to the crankshaft. Over time, this key may become damaged or broken, particularly if the engine experiences a forceful stop, like hitting a large stationary object. If the flywheel key breaks, the engine will not start. A slightly damaged flywheel key is noticeable through symptoms like misfiring, backfiring, or having no power. If any of these are occurring, the flywheel key should be replaced to prevent complete engine failure.A flywheel puller tool is required for this repair. Make sure the engine is cool before working on the flywheel. Wear safety gear, including gloves and eye protection. Disconnect the spark plug and remove the blower housing. Remove the flywheel mounting nut and set it aside. Take the recoil starter cup off the mower. Use the flywheel puller to remove the flywheel and access the flywheel key. Remove the broken flywheel and replace it with the new flywheel. Reverse the steps to put the mower back together.This flywheel key is made of an aluminum alloy and is sold as an individual part. It is designed for use in lawnmowers, lawn tractors, and other small engines manufactured by Briggs and Stratton, Toro, Lawn-Boy, Simplicity, MTD, and others.

This screw is a genuine Midwest Engine replacement part for small engine appliances, including lawn tractors, lawn mowers, snowblowers, leaf blowers, vacuums, and tillers. The purpose of a screw is to tightly link materials together through rotation that pierces into the material. A screw might have to be replaced in the event that it is lost or misplaced, a common occurrence due to its size. A screw might also be replaced if it deteriorates over time, through erosion, cracking, or piercing, thereby reducing its efficacy in holding materials together. This kind of damage can be attributed to general overuse, to age, or simply to long-term exposure. If a screw is subject to any of this kind of damage, it is best to replace it immediately, as the materials held together by the screw must continue to be held together. Remember to always wear gloves when handling, repairing, and operating outdoor equipment. This screw is compatible with the following brands: Briggs & Stratton, Toro, Cub Cadet, and Lawn Boy.

This grip-starter rope is a genuine Midwest Engine replacement part for outdoor appliances with small pull start engines, such as lawn mowers, snowblowers, wood-chippers, leaf blowers, and chainsaws. The grip-starter rope is the piece that allows an appliance user to start the engine by pulling the rope; this mechanism can be referred to as a recoil starter, a starter rewind, or a rope start as well. Any damage to a grip-starter rope will be obvious to the naked eye; while the problems with the actual starting mechanism of a pull start-operated engine might be more difficult to assess and root out, the damage to the actual grip-starter rope itself will come in the form of tears, rips, and general time-worn erosion of the casing material of the rope. If there is significant tearing on the rope itself, this replacement grip-starter rope can serve as a replacement part. Remember to always wear gloves when handling, repairing, and operating outdoor equipment. This grip-starter rope is compatible with the following brands: Briggs and Stratton, Toro, Cub Cadet, and Simplicity.

This is a fuel line replacement intended to keep a lawnmower's engine running smoothly. It is long enough to make a couple of fuel lines, just cut the fuel line to the desired length and keep the rest as a spare. When a mower doesn't start easily or performs poorly when running, the fuel delivery system may have a problem and will need repair. The fuel line that supplies gas from the tank to the carburetor may be cracked or broken. When this occurs, it is best to replace the fuel line before it becomes a flammable hazard. This is an OEM replacement fuel line sourced from the manufacturer and is sold individually. This replacement part is compatible with different Briggs & Stratton mowers. Remember to use work gloves and drain the gas tank before the installation of this part.
