Parts for Briggs & Stratton 250412-1071-E1: Alternator, Electric Starter, Gear Reducer Parts

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.

Here is a replacement armature-magneto, also known as an ignition coil, for use with small engines. The part is capable of producing a high voltage, which is then used by the spark plugs, to start the engine. When the ignition coil is not working properly, it will be difficult and sometimes impossible to start the engine. If the spark plugs are not the problem with the engine starting, it could be due to a broken part on the armature-magneto due to wear and tear, the elements, or other forces. The armature-magneto may need to be replaced if it has failed. This is a genuine OEM replacement part sold individually. Spark plug boots will be sold separately. This part can be used for many models of snowblowers, tillers, lawn mowers, wood chippers, and other small engines. Brands compatible with the armature magneto include Briggs & Stratton, Toro, Cub Cadet, Lawn-Boy, Simplicity, and MasterCut. Buyers will always want to ensure they are getting the proper ignition coil for their make and model.

This is a screw that is used in many types of lawn and garden equipment, including lawnmowers and wood chippers. It comes with a black finish and is made of durable metal. The screw can be used in many locations on a tool to attach two components together. Screws can also be used in tandem with nuts, but the two components should have the same threading and finish.Screws can become damaged, break, or be stripped and will need to be replaced. Corrosion, extreme temperatures, and unexpected stress can all lead to issues with a screw. A visual inspection can indicate whether the screw should be replaced. If it does need replacement, a screwdriver can be used to remove the original screw. The new component can be placed and tightened.This screw is a genuine OEM replacement part that is sourced directly from the manufacturer. It is sold as a single component. The screw can be used with many types of lawn and garden equipment, including lawnmowers, tillers, pressure washers, leaf blowers, edgers, generators, wood chippers, and snowblowers manufactured by Briggs & Stratton, Cub Cadet, Craftsman, Murray, Wheel Horse, Lawn-Boy, MTD, MasterCut, Simplicity, and Toro.

This replacement part is a nut. This part is small but important in various types of equipment. Nuts are able to work with other small parts such as washers and screws to secure equipment components in place.If a nut has become stripped or worn down over time, it is possible that it can no longer perform the function needed. Be sure to wear work gloves when working with small parts such as nuts to prevent injury during the repair. This is a genuine OEM replacement part manufactured by Midwest Engine. This part is sold 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.

No part of an engine is more elemental than the off/on switch. Briggs & Stratton manufacture this switch as a replacement part for more than 150 of their gasoline-powered motors, in particular on their gasoline-powered generators. As equipment that is intended to produce and maintain a great deal of power over several hours at a time, the internal connections of the generator can experience a lot of resistance, which means creating a lot of heat. The rotary off/on switch is a locus of much of that heat since it is the quick, safe way to stop the generator. As a result, the switch can be damaged by heat. Typically, the switch will reveal that it needs to be replaced by failing to remain in the on position. Replacing the rotary switch is a simple matter. Remove the plug cap and stabilize the generator so it cannot move during the procedure. Remove in order the starter rope, air filter assembly, electrical connection from cover, and four cover bolts. The old switch can be pinched out after disconnecting the ground wire. Reverse the order to install this new, OEM guaranteed replacement rotary off/on switch.

This brush retainer is part of the starter motor on many types of lawn and garden machinery. It comes with both the retainer and a set of four brushes. The main job of the brush retainer is to hold a set of carbon brushes against the commutator bars located on the armature. If the brush retainer is worn, damaged, or improperly seated, it can cause problems with the equipment. The starter motor will not be able to get the proper amount of current from the battery.If the brush retainer might be causing problems, a visual inspection can be performed. A damaged brush retainer can wear down to the wire lead and become burned, pitted, or cracked. When the brush retainer is worn out, it can decrease engine performance, reduce braking, and cause the motor to lose power. This brush retainer is an authentic OEM replacement part sourced directly from the manufacturer. It is sold as an individual part. The retainer is made to be used with lawnmowers, snowblowers, tillers, and wood chippers created by Briggs & Stratton, Craftsman, Toro, Cub Cadet, Lawn-Boy, Snapper, MTD, and Simplicity.
