Without hesitation, I tore into it and broke it down for cleaning. When I popped the metal hood off, I was a little stumped (but relieved that there weren't any black widows or anything like that). The motor looks like a typical 6.5/7 amp unit that you'd find on most Sanitaires from the 80s until about 10-15 years ago. However, according to the serial on the data plate of the vacuum itself, it was made in 1973. The motor amperage is 3.35 according to the data plate.
On the upper bearing plate of the motor, "3373" is stamped on the top. The fan is plastic (much to my slight disappointment, I would have loved a metal fan), which could mean that it was replaced because these came with metal fans, or it could mean the fan is original to the motor (as 6.5/7 amp motors came with plastic fans) and the motor itself was replaced at some point in the vacuum's life.
What does a 3.35 amp Eureka motor look like? I thought that the Eureka/Sanitaire F&G motors below 6.5/7 amps resembled the 5 amp motors (aka blender motors).
If the numbers on the bearing plate mean anything, what motor do I have, based on the picture?
Also, I think I'm going to repaint the hood as it has some scratches. The obviously unobtanium Sanitaire hood decal is something I don't want to ruin. Masking it off is easy but I've noticed a little bit of rust up at the top recess of where this decal goes on the hood. I'm not too comfortable trying to peel it off (it's an aluminum decal). Thoughts?
