This authentic replacement part is designed for use with Murray, Simplicity and Snapper snowblowers. Flange bearings are used to provide support for a shaft while reducing friction between rotating parts. The rollers take the load and spin, distributing the weight evenly while the minimal contact area of the roller reduces friction. Bearings experience constant wear from pressure, heat, vibration, and friction. Because of this, many bearings need to be periodically replaced. Make sure to check the diagrams of your model for the exact location and the correct installation of this component. It is sold individually. You will need a screwdriver and a wrench set to take apart the housing in order to gain access to this flange bearing. Keep in mind the screws utilized to secure this component are sold separately.

Eparts found parts for my obsolete show thrower
After years of service, this part wore out rendering my trusty snow thrower DOA. Considered obsolete by local dealers, I was excited to find eparts was willing and able to supply the parts I needed to bring my unit back to life. Communication kept me up to date on delivery as some of the parts were on back order. Thanks for your diligence on my behalf. AJP

you just put it back together the way you took it a part. this was small job and very easy snow blowers and lawn mowers are easy just put it back the way it was taken apart. took long time to get parts so if your not an experanced at fixing things don't take apart till you have parts or you can run into problems when putting it back together. take pictures or video that will help them that are not good at fixing things put it back together.
