Hoover model 102 needs helps! Please!!!

[vinvac1977]

Today I decided to start working on my Hoover model 102 Special. The cord was completely toast but there was enough left to put a plug to see if there was any life left. Nope deader than a door nail. Having never taken a motor apart before I decided to put my big boy pants on and try. After getting the cover off it looks like it sat at the bottom of lake.

I noticed that the ring that the carbon brushes are mounted to(sorry I don't know the technical term for it) is broke in several places. Is that something that can be glued back together?

The spindle for lack of a better term is pretty rusted, can that be sanded clean?

One carbon brush, I do know that parts name(lol), looks good, the other is stuck, I figured best leave well enough alone till I figure out if the whole thing is salvageable.

I do have a 103 that has a decent motor but needs a new cord also will that fit on this 102 to combine them to make one decent machine?

Any advice would be greatly appreciated!!

Thanks,
Charlie

The 103 used a smaller motor than the 102.

The 102 used a Robbins and Meyer motor and the 105 used a R & M motor then switched to a Hoover motor.

The Carbon Brush Fiber Ring was the same between the 102, 105 and 541.

Thanks for the reply.

So swapping motors wont work. Is there a way to resurrect this motor or should I give it a burial in the backyard?

It's certainly resurrect-able, patience and delicate cleaning.

Ah thats easy...

Just out some super glue on the two cracks in the ring, take of the two screws that hold the carbons brass holder, get out the carbons, if there a 1/4 inch or shorter replace them with Kirby ones, Take out the Field Coil (Large magnet with two wires) two screws, and pry that out with a screwdriver. The field wont come out easily due to the rust and the natural tight fit. Note the way you remove it, as you will have to put it back in facing the same way during reassembly, or the armature could scrape the field. Get a pad of very coarse steel wool, and without going over the sleeve bearing, sand that surface rust off of the bottom of the motor. Penetrating oil may help with that. Clean any rust off with steel wool, unless it has to do with carbons/armature. if the carbon or armature need rust removed, use extremely fine sand paper. undercut the mica on the commutator IF it is even with the commutator bars. The commutator bars are the copper bars at the top of the armature. Undercutting can be done with a razor. be careful not to scratch the commutator in the process. Then use 2k grit sandpaper, and sand the carbon dust off of the commutator. Sand the ends of the carbon brushes slightly as well. Use cotton swabs and clean the upper and lower sleeve bearings until the q-tips come out clean. Then use the white and blue 3 in 1 oil, and put a small amount in the bearings. Wipe off all of the parts with alcohol before reassembly. Assemble motor in this order. Field coil(facing right way), armature, Carbon brush assembly, wire motor, secure top housing cap. Add 1 drop of oil due to the fact that you already added oil to the bearings. if you want u can email me and I can send u a pic of my service manual for early hoovers.
