Have rebuilt D2 and D3C motors and notice that the air deflector gets really filled and packed with dirt after awhile. Removing the deflector generally destroys it and now they are getting hard to find. I understand the D3C is a bypass motor design where the air now goes around the motor instead of through it. Has anyone ever just left out the air deflector and tried to run it that way and how it may work? If not, I guess I will be the first.
Thank you for any comments.

If you're talking about the motor housing shell (the plastic shell around the motor) that directs the air from the basin up to the fans. It should just slide off without any damage. The air that flows thru the shell helps to cool the motor by flowing over the fins on the outside of the motor.

If you leave it off the fans are just going to suck the air that is in the motor chamber without pulling the air up from the basin, so basically you Rainbow will stop sucking up dirt. Also because the air isn't flowing around the motor it will most likely overheat.

The air deflector, under the spider wheel, is necessary and the machine cannot successfully be run without it. Worst case, find one on ebay.
