The bad news with Sanitaire vacuums is there is a dearth of information on specific models, especially older ones made before Electrolux acquired Eureka. The nice part is it's like a Model T Ford or VW Beetle. The design hardly changed over the years so parts are plentiful, cheap and amazingly cross-compatible. You can pick and choose which parts best suit your needs. They're also a cinch to work on with only the most basic of tools and skills.
I picked up an SC686 from the early '80s almost a year and a half ago and have upgraded it with a newer VibraGroomer II brushroll to replace the original that had bad bearings and an F&G bag conversion kit to replace the original dump bag setup. I also had to replace the pulley on the motor and the lower cord hook. The pulley was the real hidden problem as the original had worn impossibly thin, leaving insufficient tension on the belt. |
