Blower motor

[igotta40]

Has anyone ever taken the heater motor apart? I’m afraid if I do that I will mess up the brushes and won’t get it back together again, and it’s 51 years old. I need to free up the motor shaft for the front heater fan. On the fan end I put some sewing machine oil and Kroil but no luck. It turns but it’s stiff. Any suggestions? Thanks!

Seems to me I have seen replacement brushes for sale, so I would assume it was designed to be work on.
I'm thinking the fan end has a bearing and the other end of the shaft is a bushing. Have you look in the manuals for directions.
Perhaps @timmyisinthewell will post the phish If you give us the year.

I've taken my stuck rear heaters fan motor apart a couple of years ago. I haven't resourced brushes, because mine were fine. I cleaned up the armature and greased the motor. The brushes looked similar to ones I've seen at my local ace h/w, but Idk if they'll fit.

I’ve had mine apart but the motor was fine. But, this did peek my curiosity. Cursory search of the Interwebs.

78-83. Maybe the motor could be adapted etc etc.

At 51 years old, maybe a '74? I can find no indication of replaceable parts (bearings, brushes, etc) for the blower motor internals. Sorry not much help. Good luck with your project.

Thanks, I guess the real question I have was how hard was it to reassemble?

Thanks, I may have stated my question inaccurately, I’m not looking for parts. Did you have trouble putting the motor back together?

Depends of the arrangement, some times to get the armature in, the brushes need pinned/taped back, after the armature is in you release the brushes, by pulling the pins or tape.

It shouldn't be all that hard. Get a fair sized deep cardboard box to work in. Good lighting helps. Wrap the open top perimeter with some plastic wrap to form a ledge to help keep flying spring loaded parts in the box - leave the center open to get your tools/hands in. Much easier to find parts in the box that on the shag carpet under a desk.

For $400 I'd be fixing it or adapting something else. Go to a wrecking yard and look for similar fan motors - take one of those apart to see how they work inside.

Not that I recall.

I keep feeders out most of the year. They freeze up on a regular basis. Usually, more often than not, Kroil, 3 in 1, even WD will free them up. The fact Kroil had no affect on it says something may have broken off and jammed the shaft.

Who said anything about $400?

Usually once you take one end off the motor the armature slides/pulls out. The hardest part of assembly is holding back the bushes to reinstall the armatur. like Charlie said. Get some 500 grit or finer sandpaper and polish where the bushes ride on the armature. I always figure if something is broken or doesn't work, that I can't break it anymore than it is, and at some point some human put it together originally. You'll figure it out. You can probably find a video.

A little late but here’s some pics of what I did with the brushes for reassembly.
First, have the wire loop ready to place over the brush and the holder.
Next install the spring and use a pick to hold spring in, insert brush and place wire loop over it. Twist wire to snug. You don’t need to make it super tight.
Do the other side and place over the armature. Clip and remove the wires. The big magnets will pull the armature to one side but it will center up once the cap is placed on.
