How does this come apart? (snowblower)

Off topic, just got out of the pool and you stars are into snow, it's JULY.

Those are made to throw snow not crushed stone.

Gotta go the ice in my scotch is melting, not good it waters the good stuff down.

To tell you the truth, I've been wanting to see what it would do with a pile of grass!! Think it would move it far..... like into a wagon?

I read a post a while back where a member here had tuned up his thrower in Fall and couldnt wait to try it out, so ran it through a pile of leaves. The report was it can blow leaves...

As usual, the deeper into it we go the more we find problems.

First, the housing is cracked. A little tricky to see in the first picture but its the black line where the bushing hub meets the main body (thats a hole, not paint flake). Im not sure the material (maybe aluminum), so not sure welding is such a good idea (a good corner for stress concentration, and if aluminum then it will soften when welding).

It looks like it was worn through from the inside out. (ALL the bushings are completely shot)

Maybe some epoxy would work though.... mickey mouse, but maybe.

Then some more shots. Im not sure how far the housing is - maybe new bushings will go in ok. The good news is that there was some grease in it! (cant take that for granted....)

The gear looks 'ok', in the sense that there are some teeth. But they are fairly sharp on the tops (I might expect a small flat on the tooth tip). Research to do on that.

How hard is a decent replacement gearbox to find? And even if I did find one, I likely have to rebuilt it.

Is this fixable?

(on another front my new spline insert came so can weld that in). Some other issues but this gear box is the most serious at this point (although now Im inclined to take the other gear box apart as well).

Im on a deadline before snow comes!!

[J-Mech]

Can you circle the hole and the crack? I don't see it.....

That gear is shot. Replace it.....

[yeeter]

try this one... (my editing is limited). My thinking is that this wore through from the inside, so even where not all the way through is likely thin.

running out, back later.....

Don't ask how I know, but the single stage QA's work just fine on huge piles of leaves laying in your yard in the fall

Limited time for much research on this, but what I have found so far suggests the housing failure is due to the thrust bearing wearing out and the thing just eating up through the housing.

So a new housing assembly is needed. Plus all the bearings. And the gear. Feeling pretty pricey $$$$$

I better inspect the back gear box before going much further. If its in as bad of condition... well, there isnt much left after that.

It might be that these front gear boxes were used on a lot of models so I might get lucky in finding one used.
