Parts for Briggs & Stratton 12E100 (0007-0268): Rewind Starter / Starter Motor Parts

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 OEM replacement part is a crankcase gasket for lawnmowers. The crankcase gasket is used to seal the two halves of the crankcase. If the crankcase gasket is no longer sealing properly, it might need to be replaced. Luckily, this is a relatively simple repair. Before beginning, make sure the engine has cooled. Once cooled, locate the old crankcase gasket. Tilt the mower on its side. Once tilted, remove the blade of the mower. After removed, clean any dirt that might be on the crankshaft. Drill a small hole into the old seal and be careful not to damage the crankshaft. Insert a screw into the drilled hole and use it to pry off the old crank gasket seal. Once removed, install the new crankcase gasket. Reinstall the blade, and tilt the mower back to its upright position.This genuine replacement part is sold individually and is compatible with MTD brand lawnmowers.

The oil drain plug plays an important role in lawn and garden machines, although most only realize how important it is when it is not working properly.

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.

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.

This replacement friction spring is a genuine OEM part meant for any number of small appliance engines run using a starter rope. This spring absorbs large amounts of kinetic energy that could damage the starter rope pulley system. It helps keep the pulley from being overstretched, which would create enough pressure to break the entire system. This spring sits at the center of the pulley system and creates resistance as the user yanks the starter rope. Friction springs can become worn out after repeated use, especially if a user tends to yank the starter rope quite forcefully. The most obvious sign of a worn of friction spring is if the pulley system lacks any resistance. As the user pulls the cord, they should feel a little pull back, but if the friction spring is worn, there will be much less resistance. Replacing this part is straightforward and will only require a screwdriver. Simply open the pulley system, carefully remove the old spring, and install the new one. This part is compatible with a wide number of appliances from Toro, Vanguard, Briggs & Stratton, and Lawnboy. It comes sourced from the original manufacturer and ships individually.

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 replacement part is a switch key. This is a genuine replacement part made by Midwest Engine. This part is commonly found installed within certain lawn mowers and is able to ensure that the user can turn the machine on and off according to the desired settings. A new switch key might be needed if the current one is unable to turn the machine on or off. This can be caused by normal wear and tear over time. If the key is no longer working, it can be due to this part being damaged. This should be a fairly simple repair and should only use common household tools. This is a genuine OEM replacement part. This part is sold individually and is sourced directly from the manufacturer.

This is a fuel cut-off value that is used in over 150 different small gasoline-powered engines. Those devices that have this value include power vacuums, leaf blowers, pressure washers, and generators. The fuel cut-off valve is a safety feature that sits on the bottom of the fuel tank. In situations where the engine must be cleared of gasoline, this valve is very useful. It allows the gasoline in the fuel line to continue to the carburetor and to be combusted in the cylinder. Once the engine block is drained of gasoline, no further ignition of fuel is possible until the cut-off is reactivated. Although it is out of the way of casual contact, the cut-off can be bumped and damaged by contact with other tools, hoses, or debris. Also, since it is a narrow passage through which gasoline passes, it is possible for contaminants to jam the flow and create a blockage. If the tank is full of gasoline and the carburetor is functioning normally, an engine that won't offer to start at all may be the victim of a faulty cut-off fuel valve. This OEM genuine replacement is compatible with Toro and Briggs and Stratton engines.
