Well, after a day of whacking at it the central shaft is out.
The main snowblower shaft is attached to the auger by two bearings,
and a collar with an allen key lock that goes over the end of each
side. Fair enough. I don't see evidence of a circlip at the outside
end of the bearing but there is an inner collar that seems to be part
of the bearing race.
Tried using a puller on that; no dice. Tried a torch for 5 mins on the
inner race no dice. Finally resorted to using the dremel and cutting
into the top half of the bearing; enough that I was able to remove
enough balls (several were gone) so the bearing fell apart and I was
able to take the shaft out the other side.
Shaft is really dirty and the bearings are probably rusted on. Took it
to the shed and just dunked the good (ish) bearing side in a bucket of
carburator dip and will leave it for a week, then try pulling it off
from the back of the bearing (the "right way to do it).
Then I'll flip it over and repeat

Hi all!
Well it was 50 degrees today so I figured I'd start tearing down my
E20's snowblower. The model I have is the AD42BA model with the motor
on the left and the big chute. Pretty standard snowblower.
Haven't found any documents on overhauling it, but there is a
Elec-trak document with the parts schematic that gives a good idea of
where everything goes. 1-3-74.pdf on the third page. There might be
some instructions in the larger PDFs, but I'll just get started with
this. If anyone knows a better tear down plan let me know.
First step is to remove the motor. This is simpler than I thought:
Winch it all the way up on the tractor, then get underneath and
remove the 4 bolts holding the motor on, then break the factory wire
lug on the motor, curse, and pull the whole thing out. It's a HEAVY
motor, but oddly enough the bolts were in fine shape. In fact ALL the
bolts are coming out without issue, I guess they used high quality
American bolts or something when they built this in 1973.
Anyway remove the smaller bolts on the side to get the chain and
bearing guards off, then remove the six bolts and two big end bolts
to get the auger out. The left side is held in by a sideways H
bracket, right side just with the normal bolt in the center.
With the auger out you remove the six bolts for the drive gear, then
use a puller to remove the two collars marked 24. These have a single
allen set screw in them, one did take a bit of penetrating oil to
remove. Then I suppose you just tap out the axle, but I haven't
gotten that far yet.
Anyway, it's a start. I'm guessing the bearings are part 23 and need
to be pulled from the inside on the auger then new bearings put in.
So any clue on good replacement bearings and if anyone has an ice
scraper? For the rest I am going to clean up the motor, put in the
new chain, and spend some time reseating the skids so the blower
doesn't drag on the pavement. Then I'll POR15 the inside of the
blower housing and the chute and it should be ready for another 50
years....
