I have a solution that I'd prefer.
Take out coil and armature of d80(I like d80 better than d50). Get cr1 motor. Then get a 6 amp royal coil. Drill holes for carbon brushes. Install coil make a small hole or use given hole to run wires. Black and White wires from headlight. Black/red and white from coil. Hook to switch. This would give you one speed. I don't like safety switches. It would be easier on motor not changing speeds. I may try your idea though. I have a few extra motors. I don't have a royal fiels. The fields are made by the same company. Les |

The d80 and classic motor housing are different.
D80 is a smaller compact housing. The cr1 runs the first 16 inch brush nozzle and entirely new housing. The field coil is optimized for its engine. The carbon brushes are the same but the coils are optimized for motor housing. It could be done but something will wear out to quick. The part of the commuter getting hit by carbon brushes varies with each motor and each housing. It's not size of carbon brushes is location there placed is optimized by motor housing. Les |

In that case like all cases when I question you and im wrong.
You Al to already figured out possible troubles before you posted. I have a quiçk question. Does a k meter test rpm on motors? I've noticed you have rpms in your vacuum testing. I'm wrong but that's okay. Very cool. I should know better. The only point I was suggesting ds80 armature cr1 motor in same motor housing are not optimized for each other. Les |

"Got a D50 or D80 with a bad motor and want more horsepower and speed?"
My fully refurbished D80 tests at 125 nozzle CFM, which means a CFM density of 5.61 CFM per square inch, which is extremely high. So high that pushing effort is unrealistic on medium pile or higher/thicker carpets. I'm assuming that any "hot-rodded" machines would be primarily used on low pile and/or bare floors? On my fairly worn pile carpet, even opening the relief valve and bumping the height adjustment up one additional notch is still mostly unacceptable for cleaning 1000+ square feet of carpet. How will you be using these machines? Bill |

I thought you mismatched but you didn't.
Having a more powerful dual sanitronic is appealing. I'll have to pin this thread to make sure wiring is done correctly. You still didn't answer the RPM question. I have nicest k meter harbor freight sells very comparable to Kleins'. I have a anamometer ranked just as high as vaclabs mine was $10 more(I bought the one he uses it was defective). I have lots of tools just wondering how you measure RPMs. Les |

I never get the name correct a voltage meter. I guess Klein electrical meter is where I get k meter. Voltage meter is what I'm referring to.
I've seen laser tachometers. I have a heritage 2 13. I'd imagine it would pull similar numbers to hot rodded d50. You shouldput an omega, classic 3 or tradition front end on d50. It levels out the stance of the vacuum. When you use the toe touch it gets all 8 positions. It is better than putting wheel extenders on it. The wheel extennder screws creates slot of tension where the extenders are. The solid axle has no tension. Using wide wheels on the back too keeping balance. Ben is where I found out this. Les |

If you cut out 2 holes in motor housing in the center of coil. You could feed the wires out the sides. The wires that close to carbon brushes I'm weary of. I had a d80 coil that had metal pieces added to the coil to fix coil. One of the pieces caught a wire making it a live wire. The live wire fell towards bottom of motor. I had this happen on 2 d80ys within 2 minutes of each other. The wires caught fire burning extremely hot. I go dark blue, green, light purple yellow. The hightemperatures basically fried both d80s completely.
These were my first restoes of d80s. I put a large amount of time polishing them giving new parts trim, bearings etc. I have an extra 1cr motor from when I got 505 and 508. If I didn't wire the safety switch and just wanted low speed only what wiring mods would I have to do. I'll throw another cool piece of info. The g series hose if you take off the adapter to the housing. You then get a d80- tradition adapter a small cut let's you pull adaptor into the g series hose. Kirby collector may have got this from me as he has one. The classic face plate put on d50-d80 housing let's you fit a classic nozzle? That would mean the my classic shampoo system would work on a dual sanitronic. Les |

The first one was a wreck (never rebuilt), but still pulled around 5.0 Amps, fan only, no brushroll or light bulb.
The second one Kirby rebuilt in 1990 and I refurbed in 2018. Motor Speed = 11,152 RPM (BR Spinning) 4.8 Amps, Low Speed, BR ON, Bulb ON Motor Speed = 11,680 RPM (Low Speed, BR OFF) 4.4 Amps, Low Speed, BR OFF, No Bulb Motor Speed = 13,680 RPM (High Speed, BR OFF) 5.9 Amps, High Speed, BR OFF, No Bulb |

Rob, I don't see anything in the below videos to indicate something unusual, especially with the "lost cause" video. Can you tell if parts were upgraded?
Kirby Dual Sanitronic 80 (Bill's Lost Cause) Kirby Dual Sanitronic 80 Teardown And Bathtime These videos represent two different D80's. They are not the same machine. And I've learned through a massive amount of power testing that U.L. ratings are "suggestions" rather than absolutes. For example, I've seen 10 Amp motors run at 12 Amps under load and 12 Amp motors never pull more than 11 Amps no matter what carpet you run them on. Bill |

Rob,
From 1972-73, the Classic 1CR fan case changed from the old style used on the D50/80 to a new style to support the groove on the back of the rug nozzle casting. But, in recent replacement (since about 1979), the Classic Omega 1CB's fan case (120073) is used, and like the 120065 fan case, does not have the protrusion to support the groove on the back of the nozzle casting for the 1972-73 Classics. ~Ben |
