Kirby model 2C help needed

I never thought of using the inner side of those wheels. They're aftermarket and I can still get them from a vac supplier. They would've replaced the rear wheels of the Classic 1CR, Omega, & Classic III.
 
You

Have to cut the inner lip flush with the width of the tire or the wheels won't fit.
I told Thomas you'd be getting a hold of hi.
 
side note

If anyone can look at the previous post I did, before post 41, I mentioned how I'm not sure on which way the wiring for the carbon brush holders are supposed to go as well as the position of the field. I need to know which way the wiring goes in order for my Kirby 2C motor to run in the proper direction and not in reverse. I had everything reversed and I'm trying to correct the issue, but unsure on which position, orientation the field and wires to the carbon brushes are supposed to go, for my motor to spin in the right direction. I need some help, please. If bikerray or someone can help tell me what I need to do and how to position the field, in the right way, that would be great.

Rotate

The field 180 degrees. Make sure the wires are connected to the carbon brush inserts. It's hard to give directions with no pictures.
 
Ok, the field is in correctly

Looking at it from the front

The lead from the bottom field goes to the right carbon brush holder
The lead from the top field goes to the left carbon brush holder
 
Question

If you did rotate the field 90 degrees as you stated.
How did you cram it back into the housing?
The field coils would have hit the carbon brush holders.
 
note

I was wrong, when I first reassembled my Kirby 2C, a made a mistake and put the field in upside down, which I reversed the wiring connections to the carbon brush holders. That's why the motor ran so slow and in reverse when I tested it, before I took it apart again to fix the issue. As a side note, I wrote down which lead from the field goes to which carbon brush holder. Bottom goes with right and top goes with left. Just one last question, What way should the field itself be inserted into the motor housing? I took it out again to reposition yesterday, but haven't put it back in yet. I now know how to properly connect the wiring to the carbon brush holders.

If

Your 90 degrees is referring to my directions surely you misread. I said 180 degrees. If you rotate 180 degrees changing the location the bottom of the coil connector to the carbon brushes.
Liam the side that has the coil where the wires are on the bottom of the coil.
 
note

I did connect the field wires to the carbon brush holders correctly. The bottom wire of the bottom field coil, goes to the right carbon brush holder and the top wire of the top field coil, goes to the left carbon brush holder. I did take the motor to a expert vacuum repairman at a local vacuum store. He reassembled everything, except for the wiring connections to the foot witch assembly, that has yet to be looked at since I was the one who connected them myself, before I took it in for a look. The foot switch was already assembled by me, before I took the motor to the vacuum store. He then tested the vacuum and the same thing happened, the motor ran very slow, slower than normal. He and I decided that the issue with the running of the motor is now not the field wiring to the carbon brushes, which has been corrected, but rather the electrical connections and wiring hook ups to the foot switch assembly. Does anyone think that maybe the real cause of the issue, is the wiring connections of the foot switch. Are the wiring connections to the foot switch hooked up in the wrong way, in reverse? If so, how should I properly connect the wires to the foot switch. All I know is 2 wires go to the headlight harness and the other 2 go to both field coils, but one of them goes into the safety switch assembly. How should I connect the wires properly, since there are no black and white colors of wiring, all wires are just black.
From Liam, I will post pictures as soon as possible.
 
The

The safety wires have positive and negative. The headlight has positive and negative. The coil has positive and negative. Connect the positives together and connect the negatives together. When you turn the power on if the headlight comes on, brush roll spins and everything that powered up powers off when you flip the switch its wired correctly.

The last picture

The wires on the left with copper probably go on the terminal opposite the power prongs. The right 2 wires in pic for connect to the connection closest to the power prongs.
When you turn it on un hook the belt and the brush roll. This will make the motor spin faster.

Are you saying that the two copper wires for the headlight harness actually go together and connect to the terminal opposite of the power prongs and the other two wires with silver looking copper, the one safety switch wire and the one field wire, also go together and connect at the terminal, closest to the power prongs. If I am correct, than that is the entire reason why my Kirby 2C motor was running so slow, because of the wiring being hooked up the wrong way to the foot switch assembly.

idea

If I were to put the two headlight wires together and connect them to the bottom terminal, opposite to the power prongs and the other wires, the silvery looking copper wires, one goes to the field and the other to the safety switch, connect them to the top terminal closest to the power prongs, will this make my motor run properly and a lot faster than it did? Is this the proper way to connect the wiring to the foot switch, so that the motor will run a lot faster than it was?

Im

Lost at what your saying.
The two headlight wires are one positive one negative. The wires cannot connect together. The safety switch has a positive and a negative and cannot be connected together. The field coil I believe is positive and negative.
You have to connect all the positive wires together on one side of the switch. The other side connect all the negative wires. If you unhook the safety switch wires altogether they are not required for the machine to run. They safety wires are when the power is on you have to engage the safety switch for the vacuum to power on.
You had to have it wired correctly when the coil spun backwards. The only thing different you had to do is rotate the coil and switch what carbon brush the coils connected to that's it. I don't know what the local vac shop vacuum guy said but without doing specific things he couldn't tell for a fact it was going slower.
The vacuum is 90 years old .
Hook it up how it was working and leave it. If it turns on its wired right. With positive and negative wires if it's wired wrong it won't power on period.
If it turns on and spins it's wired right. It's simple don't overthink it.
 
Before you create Armature Flambe

If it's running slow it's either mechanical or electrical resistance

Have you thought about systematically finding the problem?

Does the motor spin free (meaning is something binding)?

Have you tried connecting just the motor (without the safety switch, light etc.)?

If the motor is OK then the problem is elsewhere in the electrical system.

Did you wire the motor in series with the light?

Is the problem in the safety switch?
 
reply

All wiring to the foot switch and carbon brush holders was wired up correctly by me as recent as yesterday, before I took it apart again and the vacuum did turn on with the headlight, however the motor ran very slow and I even noticed a burning electrical smell, when I tested it for 5 seconds. Everything was wired up correctly but still the motor ran very slow. It was not like this and the vacuum ran much faster when I first got it, before I took it apart for polishing. I think the cause the whole time is either the field or armature has gotten shot. If the field has gotten shot and has bad windings in it, it should be replaced immediately, fortunately I do have a spare field for a 2C. Do you think the reason for this could likely be a field with shot windings or is it the armature? If it's the field, I will replace it.
Thanks From Liam
 
note

Everything is in right, the armature and fan does spin freely when the vacuum is off, but when I turn it on, the vacuum runs very slow. I think it could be an electrical issue, either with the safety switch or the field or armature is shot, has bad windings. What do you think the issue is with the running of my Kirby 2C motor?
