This is an authentic OEM replacement flange bearing sourced directly from the manufacturer that is a component in many different lawn and garden machines. The flange bearing is used to tightly fit between two connected components. This connection creates an airtight seal. Over time and with normal wear and tear, the flange can become worn and lose the seal. When this happens, the flange will need to be replaced. The flange helps to distribute the weight load in some instances and if it is damaged, the weight would be displaced and could lead to serious energy.Replacement depends on the location of the flange that needs to be replaced. Place the equipment on a flat surface and disconnect the spark plug wire. Take the machine's components off as needed to access the flange and remove it using a pair of pliers. Clean off the components where the bearing was located before installing the new flange bearing. Reassemble the machine using a reverse process.This flange is a heavy-duty part that is sold as an individual item. The flange bearing can be used with lawnmowers and other lawn and garden machines manufactured by Craftsman.
