This replacement governor gear is a certified genuine OEM part for a lawn tractor or mower engine. The governor is responsible for regulating the throttle. The interaction of the governor spring and governor gear works to position the throttle in such a way that it only allows a set amount of fuel into the carburetor. With less fuel in the carburetor, the engine will run slower. In this case, a slower engine means slower blade rotations. Like any gear, the governor gear has teeth the spin against another gear. Over time, the constant gnashing of gear teeth will cause the gears to wear down and possibly slip out of alignment. Once a gear is out of alignment, it will either stop working completely or degrade more quickly and should be replaced as soon as possible. Replacing the governor gear will require disassembling the engine cover and should be done in accordance with the owner's manual and manufacturer's instructions. This replacement governor gear is a high-quality part sourced from its original manufacturer. It is compatible with engines made by Briggs & Stratton and Toro. This shipment includes a governor gear and the brackets required for assembly.

This replacement valve seal is a genuine OEM part for a lawn tractor or mower. The valve stem is a type of valve that transfers oil into the cylinder and then immediately reseals due to the pressure in the chamber. However, if the seal is damaged, it will not close and oil will leak into the cylinder. If this happens, the cylinder head may become overly lubricated and not run well. This seal helps prevent that from happening. It fastens to the intake valve and valve stem keeper. Seals will naturally wear out over time due to stress and exposure to corrosive oxidizing agents in an engine. When this happens, the valve will leak oil. To test if the valve seal is compromised, look for whitish-grey smoke that indicates burning oil and also measure to see how much oil the engine is consuming. If the seal is breached, use a screwdriver and socket wrench set to change out the part. This top of the line replacement valve seal is compatible with Briggs & Stratton, Toro, and Lawn Boy lawn tractors. It is sourced from the original manufacturer and ships individually.

This replacement exhaust gasket is a certified genuine OEM part for a lawn tractor engine. This gasket helps to seal off the exhaust from the carburetor. For an engine to run, it must first mix fuel with air to prepare the fuel for combustion. By sealing off the exhaust, this gasket allows for fresh air to enter into the carburetor from outside the engine rather than from the exhaust. Gaskets often degrade over time due to the stress of pressure and heat. If the exhaust gasket breaks its seal, it can affect the engine's overall performance. Be on the lookout for an especially noisy engine that doesn't provide as much power and is less fuel efficient. There may also be a noticeable burning smell coming from the engine. To replace the exhaust gasket, use a socket wrench and wrench set to remove the air filter and blower housings, then remove the exhaust manifold and switch out the gasket. This replacement exhaust gasket is compatible with engines made by Toro, Briggs & Stratton, Murray, Snapper, and Simplicity. It comes sourced directly from its original manufacturer and does not include any additional hardware.

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.
