This grease plug is a genuine OEM replacement part sourced directly from the manufacturer. It is found on snowblowers and other outdoor yard machines on the gearcase assembly, which houses the auger gear. The grease plug seals the oil port on the gearbox. This keeps lubrication inside the gearbox and is the access point for adding more when needed. If this plug is lost, the gearbox's oil could leak out, and contaminants could get into the gearbox.Lubricate the contents of the gearbox before installing the new grease plug. Locate and remove the two screws on the side to drain the gearbox. Install the grease plug in the bottom. Refill the oil using the vent hole. Continue filling until oil is coming out the top side screw. Close everything back up, and the machine is ready for use. To prepare the equipment for long storage, remove the grease plug and check the oil level. If it is not to the top, add more lubricant before sealing the grease plug.This grease plug is made of durable black molded plastic and is sold as an individual unit.
