How does this come apart? (snowblower)

[Sam Mac]

Sorry I can't be of more help but I've never had to work on one. Keep us posted. I'm sure some of the members can help you on this one.

[J-Mech]

I've had them apart before. So have other members. Just ask if any questions. Matter of fact, I still have one apart...... Maybe it's a good time to fix it, like as in before snow flies.

There is a roll pin throughh the impeller. But that didn't matter. When I unbolted the gearbox it slidright off the splines.

The splines on the shaft seem 'ok' (needs closer inspection).

But the mating splines on the ID of the impeller are shot. Completely. (Pics coming... As soon as my son finishes his video games)

So I need either find a new impeller, or get creative on fixing the splines on the ID (too big for my lathe to swing and this would need to be in balance reasonably well, so just any old hack job won't do)

Also the back side of the impeller was starting to rub the housing (some thrust load wear, or adjustment needed)

It was time this thing got an overhaul.

Q3). How hard is it to find a replacement impeller (and how $$$$)

Q4). Instead of replacing, any ways to repairing a spline ID?

That roll pin holds the drive shaft for the augers. Actually the impeller floats on the splines. If it was into the housing, you may want to disassemble the auger drive box. There are thrust bushings in it.

I had mine out for repair, had a buddy of mine who builds driveshafts balance it on his driveshaft balancer.

Still available from cub, just go look it up. Hang on to your butt, it's pricy!

Yes, I'll go see if I can find the thread. Someone on here rebuilt his last winter. I think I may even have the spot bookmarked for where the splined bushing came from.

THANK YOU!! ($160... yikes!) Some pondering to do on how to pull this off but indeed doable

Here is what it looks like.

Its worth taking the gear box apart. And the worm drive also. And anything else while I have it apart. The worm drive seems to have some play in it (when I turn one direction, then back in the opposite direction, it rotates a bit before engaging).

But one thing at a time. So far - Im for repairing it back to working order.

[J-Mech]

Tear apart the worm drive. If it's original, it has an aluminum gear. If so, there is a replacement brass one. That's why mine's apart. I haven't put it back together yet.

Here's mine:

where did you source that worm gear from J-mech? I found one (>$100), which motivates me to do a close inspection first...! If it were more reasonable I would just replace while I have it apart.
