A voltage regulator is an important piece when it comes to regulating and stabilizing the electrical currents of a piece of machinery. It is designed for use with outdoor lawn and garden power equipment that have small engines, such as a lawn mower, a snow blower, and a wood chipper. It is compatible with products by brands such as Briggs & Stratton, Toro, Cub Cadet, Lawn Boy, and Simplicity.The voltage regulator part is crucial to the machine. Specifically, it is a 5-9 amp regulator for small engines that are commonly installed on a variety of lawn and garden equipment. It is designed to be an exact replacement for missing or damaged components on a new unit. The purpose of the voltage regulator is to regulate electrical voltage within the machine as it operates.The replacement or repair process of the voltage regulator should be straightforward, although a screwdriver and pliers may be needed to complete the replacement process. The user replacing the part should always be sure to wear gloves during any assembly, replacement, or installation processes. The user should also refer to the owner's manual of their equipment and any guiding diagrams that clarify the placement location.

This starter drive is a part of the starter system that helps to engage the engine. When it is energized, the gears are activated and turned, which engages the flywheel and starts the engine. This is a critical step in the firing process and lawn equipment will not run if the starter goes bad. Over time, gears can wear out and other damage can occur, resulting in a need for a replacement of the entire assembly or certain parts. It is generally easier to replace the entire assembly. This OEM replacement electric starter drive kit is designed for use with select Briggs & Stratton engines that can be found on various equipment, including lawn tractors and lawn mowers. The kit features a new style starter along with a retainer, composite drive gear, starter gear, return spring, retention plate, clutch drive, and the washer and clip to ensure a secure attachment of all parts. It is important to disconnect the spark plug before working on engine components. This starter drive kit is sold as a single unit and comes with a total of nine pieces.

Flange screws have a flange located near the top of the screw, which helps to distribute the connection force over a larger area to reduce potential damage to the machine. It also allows the screws to be used in oversized or irregular holes, and it helps to ensure they stay in place. This flange screw also has a hex top. Screws can last for a long time. However, they may become corroded or worn over time and need to be replaced. They could also become lost and need a replacement. Without all of the screws in the proper places in a machine, it could vibrate too much, which could render it less effective or unsafe to use. The flange screw is a genuine OEM part that can be used with many types of machines including lawn mowers, snowblowers, tillers, pressure washers, leaf blowers, generators, wood chippers, and other small engines. The screws are compatible with Briggs & Stratton, Craftsman, Toro, Cub Cadet, Murray, Lawn-Boy, Snapper, Simplicity, and MTD.

A spark plug boot is an important piece of rubber hardware. The purpose of the spark plug boot is to connect the spark plug to the magneto. It is designed for use with pieces of outdoor lawn and garden power equipment that have small engines, such as lawn mowers, snow blowers, tillers, pressure washers, leaf blowers, generators, and wood chippers. It is compatible with products by brands such as Briggs & Stratton, Toro, Cub Cadet, Snapper, and Simplicity.The spark plug boot part is important to outdoor equipment with small engines because it safely connects the ignition coil to the spark plug. Naturally over time, and with the wear and tear from use, the rubber material on the spark plug boot may dry out, crack, and fail, and will require replacement. Luckily, the replacement or repair process of the spark plug boot should be straightforward, but the user replacing the part should always be sure to wear gloves during any assembly, replacement, or installation processes. The user should also refer to the owner's manual of their equipment and any guiding diagrams that clarify the placement location.This spark plug boot is made out of rubber. This spark plug boot is an original OEM part sourced directly from the manufacturer, Midwest Engine. It is sold individually.

A pinion gear is a small cylindrical component that is integral with a rack and pinion mechanism. Together with the rack, its primary function is to transform rotational movement into linear motion. Machines like lawnmowers and lawn tractors have a rack and pinion system. When the steering wheel of a tractor is moved, the gear will rotate, which engages the rack. Although this component is exceptionally durable, it is still subject to wear and tear. Some symptoms of a bad rack and gear mechanism include a loose or tight steering wheel and a grinding noise. Performing a do-it-yourself rack and gear replacement is possible and takes only 30 to 45 minutes. If the rack is in good condition, but the gear is not, omly a pinion gear replacement may be needed. This brand-new, genuine Midwest Engine 695708 pinion ensures quality and compatibility with lawn tractors, generators, mowers, and engines from Midwest Engine, Briggs & Stratton, and Craftsman. The gear is sold individually. An original Midwest Engine Gear Ring is not included.

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 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.
