- It turns out that I've blown out the gearbox on the auger... it wasn't just an issue with the belts.
In this video I strip the front end down and replace the worm gear in the gearbox, re-grease it, reassemble it, and put my snowblower back together with the proper shear pins.
Enjoy!

The Flintsones wheels on front are nice.
😂
I liked that you mentioned that there is a flat on the rear bushing as well as the front. Very nicely done.
Great video ! Definitely guided me from start to finish , thanks !
Hi, I really got alot out of your video, a guy has a nice 7hp blower that the auger does not turn and wants 50 bucks, and I think I will buy it. You did a nice Job!! Thanks
Thanks! Best of luck with your project!
I think you got pretty lucky that the augers didn’t seize to the shaft. I see many that way, then it doesn’t matter what you use in place of a shear pin. it also adds a couple hours to this project.
I've got one side seized to the shaft like you mentioned. Any recommendations? The pin is stuck too
You’d need to first remove the auger from the blower. I would remove everything out of the free side ( after taking off the free auger make sure you clean the shaft surface) coat the seized side in penetrant from all angles. Let sit For a few hours and apply more then Put the open shaft in a vice. You will need to take the shear pin out first. Probably will need to hammer it out. once the shear pin is out you can try to twist the auger against the shaft. If it’s not budging you will need to add heat.
You should be using low temperature grease more like Stens 00 grease
What is the purpose of the wood wheels?
Ah yes. A very stupid addition. The driveway is now fancy concrete and scraping a metal blade across it all the time would damage it. I added those wheels to ensure that the metal auger and metal blade (at the back of the housing) wouldn’t scrape against the exposed aggregate surface. It makes the thing extraordinarily difficult to use in heavy snow and does a lousy job of clearing the driveway/sidewalk. But at least I’m not scratching up my driveway’s finish.
@@mewooshi have this snowblower and the sliders are metal and catch on everything. I can see why you put wheels. One guy on here used large bearings.
I need to do this on my machine. I thought I was going to need to buy the whole assembly
Technically the worm gear is on the shaft and the worm wheel, that is worn, is in the gearbox
Hm. Curious… I’m getting both “worm gear” and “worm wheel” for the ‘disk’ part, and then “worm screw” and just “worm” for the ‘shaft’ part as well. In truth, I didn’t look it up before I started shooting. But thanks for the tip. Any uncertainty that can be avoided is always a win. Cheers!
great video. Bet you won't be using bolts anymore. haha!
Shouldn't you use gear oil instead of grease??
I don’t believe so. According to my research I used the right grease. It definitely had grease in it originally, and gear oil would just run out the rubber bushings by the looks of it. It’s not a particularly well sealed unit.
@@mewoosh shit maybe that is why my gearbox leaks??? I could swear mine said gear oil....... maybe I am completely wrong
