So the question remains... Which two wires do I short together to get the motor to run at low speed? I don't have a coil/switch diagram handy, so I'm unsure at this point... Bill

Devin, Did you happen to notice the power usage difference? Yours was 1013 Watts and mine (Thomas') tested at 1398 Watts both without the PN running. That's around a 38% difference, which is significant. Bill

Once Again You're Completely Wrong Alex, One day you might understand the Physics and Mathematics behind how vacuum cleaners actually work, but today isn't that day. Your suction contraption is best used to test for leaks in any vacuum system not cleaning power. And since you are completely...

Vacuumdevil, I was going to leave your comment alone but Since you insist in perpetuating a flat out lie about water lift and airwatts, I'm just not going to stand for your shenanigans any longer. For a proper technical explanation that is 100% mathematically correct, watch this video...

A bit late, but I just wanted to basically confirm Blackheart's measurements. Obviously, this E2 runs quite a bit better (and uses more power) than his sample.

Replies to suggestions To LesinUtah: 1. Bad safety switch <- probably 2. Bad power switch <- maybe 3. The motor is not grounding out or power is grounding out. <- possible Thanks for your kind words, Les! =================================== To TexasKirbyGuy: If it ran before you worked on...

Got My Bearing Puller And now I can re-build the rear bearing (it has a rubber seal).

Foot Switch Wiring The #1 blue-ish wire was so loose that it practically fell off, so I tinned it and shoved it back in. It's a tight connection now.

Two Speed Switch Wiring Here's my best guess with the two speed switch. The yellow was loose, so I tinned it and shoved it back in. It's a tight fit now.

My wonderfully polished D80 will not run after re-assembly. The headlight comes on and I've checked for power at the brushes (brushes removed of course) and I see 121 volts, sooo I need help making my shiny beauty run once again. I know these machines had issues with switches and wiring, but so...

Kelton, I've performed extensive bag testing And here's some of the results: How much do you pay for your paper bags? I normally get a six pack of Kirby HEPA bags (various versions) for around $12 on eBay. Then I had an idea: turn them inside out and blow them out with a Kirby. And guess...

Les, all your numbers appear in range, except That RSL4 obviously. Can you re-test? I think Devin tested a similar model awhile back and got around 91 nozzle CFM on high speed. So if 91 CFM on high is correct, instead of: "I got 7007 reading on high speed so 7007 x .034880 is 244.40 cfm."...

That's probably pretty close Zan What I usually do is look at the inner diameter of the detector, since all the airflow will be directed through that opening. The inner "hole" might be ever so slightly bigger than just the vanes themselves. But the rest of your calculations appear to be spot...

First you have understand what suction and Airflow actually are before you attempt to design a test.

One to five microns? The only way to properly test particulate removal is to perform the tests as I have done or purchase a particle generator that can emit fine particulate at the 0.3 micron level. One to five microns is huge. Bill

Full tests are on my YouTube channel I measured 96" at the canister and 92" at the hose end, bag installed. Bill

Well, I was going to say "someone beat this", but I see that Mikko (Vacuumtests on YouTube) has a Philips that uses around 1900 Watts and gets 92 nozzle CFM. Go Mikko! Bill

Les, Where Are You Getting Your Figures? My Sentria II weights 23 lbs. and older G-series machines weigh 24 lbs. So if you have a newer Kirby, it's only 3 lbs. heavier than a 10 Amp Royal. I have two Heritage II Legends and they both weigh 19 lbs. Bill

Forgot to mention that Your Heritage II is stuck running on high speed, which is really just meant for a hose attachment. In low speed, it'll measure right around 120 nozzle CFM. Bill

Hey Devin, I Think You Meant To say that the Sentria 1 gets 127 CFM and the Sentria 2/Avalir gets 137 CFM. :) And that's with only a 7 Amp motor instead of a Royal's 10 Amp motor. Bill
