Colby,
Luckily you can still get certain replacement parts for these machines.
1-259319-000 is your replacement top cord hook (it replaced 1-259318-000). Other hardware to go with it would be 1-003884-000 for the spring, 1-597743-000 as your top cord hook mounting screw, and 1-884708-000 as the top cord hook stud.
1-672270-000 is your replacement rug plate (if the brush roll in it has hex ends), otherwise you'll need to look for discontinued part number 1-285270-000 which was used on nozzles whose brush rolls have square ends.
Good luck finding what you need!
The type of oil to use is medium-weight SAE 30. Never use lightweight or sewing machine oil. Royal recommends you oil the rear bearing approximately once a year for general household use; but if used more often, then oil the bearing more frequently. When oiling, apply three or four drops, and take care to ensure that the oil enters the tube and does not overflow down the edge of the tube.
