(ET) Tearing down the snowblower

[Chris Zach <cz alembic crystel com>]

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....
