Please advise of how to remove and install this part.
Answer Hello Barry. There are screws securing this part to number 5 in the diagram. You will remove those screws and then you can remove and replace the spacer on the unit.
does this part come with roller
Answer Kropter, Sorry, but no it does not. You will need to transfer the roller, spacers, and screws from the original spacer or purchase the additional parts as needed. Good Luck and Thanks
