Parts for Briggs & Stratton 40N877-0039-G1: Crankcase / Sump Parts

This replacement oil drain plug is a genuine OEM part for a lawn tractor or generator engine. The oil drain plug connects to the base of the oil tank and allows the appliance owner to drain used oil and replace it with new, clean oil. The oil drain plug is threaded to screw into the oil tank and prevent it from popping out of place while the appliance is in use. The most likely reason to replace an oil drain plug is if the old plug's threading has become stripped and no longer holds onto the oil tank. Alternatively, the plug is quite small and could easily be misplaced during an oil change. If lost, oil will leak from the engine, causing parts to overheat. Fortunately, replacing a lost or damaged oil drain plug is simple and only requires screwing a new plug into place. This replacement plug is a high-quality part that fits Craftsman and Murray products. It comes sourced from its original manufacturer and ships individually, without any additional hardware.

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.
