Nick,
Thank you for making this! Yes, I wish that Eureka could have made such data available for us back in the day!
I know Hoover did once, in the 1960s.

Have you checked whether or not your brush roll's bearings have seized (as kirbylux77 said), or if your motor fan is broken (missing or chipped blades)?

The 3320 had a long run from 1976 up to 1991, while the 3711A came out in 1981. The 3711 was dropped after 1985, being replaced during that year by the 3712.

Paul,
This also makes me wonder if the current Sanitaire logo with the stylized "S" also first appeared that year?
I'd love to hear from somebody who remembers buying an S639, S644, S646 or S648 in '82!

Another way to get the RD series belt to cooperate would be to soak it in warm water for a few minutes, this way you can stretch it out a little more.

Midway through production of the 1951 model 511 (S/N 383346 and earlier had the riveted plate; S/N 383347 and up had the revised plate with screws).

Edgar,
Here is the exact link about David's 505. Originally, he was going to send in his 513/14/15 (the model tag on that one was since gone) to them but he shortly thereafter found the 505 on eBay and then he decided to focus on getting that rebuilt instead, which is why the rebuild agreement...
Yes, they did. The specific front and rear bearings continued to be used even after Kirby changed the motor design with the 1956 model 516, up through to the 1970-73 Classic 1-CR.

Stan,
Glad to hear back from you, and awesome you went ahead and bought it!
Sorry to hear about the slip-up from the vac shop that last tried to repair it.
~Ben
Jeff,
That is correct about the bag being replaced on yours, also. The light blue bag I see here was taken from a model 870 Prince II upright circa 1987.
