Rainbow D2 Reassembly

Top bearing plate

I have rebuilt just a few, maybe, 6? D2, D3 and have been able to drill out the rivets on the bearing retainer replace with a stock size bearing, 6201, I believe it was, and pop rivet the plate back in place for a fraction of the cost. So far I have not had any issues with any of them. Has anyone else attempted that as well?

Clean Motor, NICE!!

Was wondering how you got the motor so clean. any tips? Also, I ave never seen running two motors in tandem like that and have never done it. Can you enlighten us as to why that is done to run in the brushes? Thanks!

If you don't have a variac, you run them in series to cut the voltage in half, so you are running the motor at a slower speed to seat the brushes.

Such impressive work!

I always like seeing these posts. This takes a great deal of work.

That's a factory original 2 wire power nozzle receptacle. The first models with power nozzles used (at first) a Whirlpool "L" shaped power nozzle, then the Oreck power nozzle, then the Eureka nozzle. They used 2 wire nozzle outlet until the second run of the Eureka power nozzle, when it was changed to 3 wire. The change to 3 wire came in 1975.
