I removed both fan stages and the two screws that run from the brush holder all the way down to the base. The field and brush holder are both free to turn a bit, which you can see in the second image, but neither the base nor the brush holder will come off. Something tells me I will need a press to get the armature out, but I don't know. I've never tried this before. Please if you can advise me of my next step. I want to remove the fields and the armature, blow the motor clean, grease the bearings and dress the commutator for new brushes. Thanks.

Insert two of the same size and lenth screwdrivers between the bottom of the coil and the motor plate, Use them to lever the coil up and off. A press is best but this will work too.

Gsheen, thanks. Your tip got the armature out of the field, and the brush holder popped off in the process. A little mystery is that a flat washer and an irregularly shaped spacer or spring came out of the brush holder and I am not certain which order they are assembled.

It appears I still need some sort of bearing puller to remove the upper bearing and a press to push the shaft out of the bottom bearing? Is that how it is accomplished? I have no idea how some get in there and repack those bearings with grease. The upper bearing feels smooth as a baby's butt, the bottom bearing is a touch gritty so I guess it gets carted off the the vacuum shop in Lancaster. Not sure I can go any further with it with the tools and knowledge I possess.

Thanks again gsheen.

You should be able to buy a bearing  at a local auto or hardware store.

 

Will post pics of the one I have. If you post pics of the washers I should be able to tell you which way they go in. If not me then someone else on this forum should be able to

I'll post a couple of photos tonight. Getting the bearings isn't the concern, it is getting the bearings out that I am probably not equipped to do, both tool and knowledge wise. I routinely remove wheel bearings from motorcycle wheels and have great tools for that job, but those go inside the inner race and I heat the wheel to 110 degrees C before I pull the bearing. This is much smaller and I don't have good tools for this job.

Sorry I meant bearing puller.You don't need heat with these bearings. You can even make your own bearing press using a Hydraulic jack
