Time for New Vacuum Cleaner ?

I got the fan off, with some wriggling from a flat screwdriver. The
shaft with the electro parts on it came out. There appears to be a
race for the bearings on one end of the shaft, the end with the metal
fan, and the race spins freely on the shaft. The other side of the
shaft, which had the white plastic fan, looks pretty loose, and the
only force holding the shaft in place there seems to be 2 springloaded
opposing metal posts which push in on either side of the shaft as it
spins between them, on grooves in the shaft. Maybe there were ball
bearings in those grooves?

I did find a broken washer on the outside of the shaft, near the
loosened nut.

Maybe a race got sucked up into the bag at some point?

Still scratching the head.

Thanks a meg John. That is the model, and I think the diagram will
help me figure out how to get to the motor.

Looks like they do have the motors in stock, which should help if I
can't find the bearings. Thanks again!

My wife had put it out in the carport for the next Salvation Army trip
but
I just brought it back in the house. Will explain when she comes home.
 :)

I suspect that it will be a sealed motor and only available as a unit.

Sometimes the fan cover is pressed onto the motor cover and you have
to tap around the perimeter of the cover with a screwdriver and hammer
to get it off.

I got the fan cover off, but the nut holding the fan to the shaft[?] won't
release.

Even when I hold the shaft with a pair of vice grips, the nut turns but
seems to be on some kind of press fitted device rather than threaded
directly onto the shaft.

I did manage to cut myself, a bit, on the edge of the fan. :(

Even when I got tired of using the wrench and put my motorized screw
driver/drill onto it, it just keeps spinning but not unscrewing.
I think I may go with a new motor. :)

By now I realize that I was turning the reverse threaded shaft nut the
wrong way, stripped it out and ... I was right, I do need to go with a new
motor. :)

I suspect that the two "2 springloaded opposing metal posts" are the
brush holders that supply power to the comutator.

Photographs would help identify the various bits.

I did find a broken washer on the outside of the shaft, near the

OK. Here is a test of sending up a pic of the removed shaft.

Yes the groove that you see near the commontator assembly is the remains
of a formerly supporting ball bearing unit. Probably the bearings were
ground up by friction because of lubricant retainer failure (the washer
that you found near the nut) and ingested into the dust bag.

Looking at the housing past the brush assemblies you will find that the
outer race is still embeded in the outer housing. It's the brass coluored
ring in the end of the assembly there in the picture is the outer bearing
race what is eft of it.

Since these bearings are usually pressed on the motor shafts it will
probably be a hard thing to fix but you likely can find a sealed bearing
that would do the job at most industrial or automotive bearing supply
houses It should be exactly same dimensions as the other one.
 
Gnack Nol,


Thanks. Do you think I'll have to pay someone to press a new
bearing unit on ? Need special tools? The brass colored race looks
like it is part of something which is riveted onto the housing with 3
rivets. I would guess it would have to be "unriveted" somehow. Geez.

It would likely take a bearing press to remove the old damaged race and
install a new one. You would probably do best to locate a starter and
alternator repair shop and ask them they might even have a source for the
bearing.

It looks like the old race (the brass component) should come out through
the area where the brushes are into the motor windings not the other way.
And is just lightly fitted into the housing. The rivets are likely part
of the end retainer retainer cup and do not have to be removed since it
comes out into the winding core.

Look at it carefully and it should be the same size as the complete
bearing's outside race is.

Just my guess.

Gnack

Nice photos ! The bearing inner race is still attached to the
commutator end of shaft behind the nut. The bearing outer race is
fastened between the riveted plates just visible in the second pic.

You will have to drill out the rivets to remove the outer race. Then you
will have to either replace the rivets with new ones, or use blind
bolts and nuts. Its likely that these will only be available as part
of a repair kit which will also include the bearing and probably a new
pair of brushes.

Note the inner race should pull off the shaft without too much
difficulty. A little heat will help. Sometimes a dab of superglue is
used to prevent disassembly.

Note: The bearing that has failed has to be re-fitted into the housing
first ! The shaft is inserted after the brushes have been lifted out
of the way. It is a push fit into the bearing.

I took it to a repair shop. The repairman said it would be cheaper
and better for me to buy a used motor from him. It was only $15 so I
said OK. I still have the original motor for spare parts.
Thanks for all the info, to all those who assisted me. BTW, I
installed the used motor, and the vacuum is running fine again.
Thanks.
