Question Auger drive repair Storm 5024

The blower has run like a champ until today. The 2nd stage blower is spinning fine but the auger now slips. The auger turns sporadically and not with a strong bite anymore. It doesn't take much snow to stop it completely. I am hoping that this is just a shear pin or dowel pin problem, quick and easy to repair. All the shear pins on the auger shaft are good but the whole shaft is no longer powerful under load. More snow coming tomorrow.

I looked up the schematic diagram and see that there is a dowel pin, (part 43) and I wonder if this could have sheared and if that would account for the symptoms I have described?
https://www.partstree.com/parts/troy...auger-housing/

It says the pin is compatible with this
Troy-Bilt 5024 (31AH63N2711) - Troy-Bilt Storm 24" Snow Thrower (2007)
Those are the same numbers on my machine except that mine is 2005. is that a compatibility problem? Is the same dowel pin used in the 2005 model also used in the 2007 model?

Is there a protocol to inspect and replace this dowel pin to see if that resolves the issue before I dig into it deeper? I haven't ever taken one of these apart before. Can someone please walk me thru it?

First, Make sure the belt is tight. If the Impeller spins Fine, and the Rakes do not, the Bronze Auger gear is Most likely Toast, part #45.

I have split open the housing and can see that you are correct.
The worm gear is shot.

What I don't see is an obvious way to remove the housing and rakes from the impeller shaft. It's obviously held in place and probably that dowel pin #43 is keeping it in place or so I suppose. I don't really know. I have also unscrewed the bolts on the two lateral sides of the rake shaft that hold it into the outer frame. It's all lose and the gear housing is split apart about 1/4" but that's as wide apart as it will go.

What are the steps to remove the housing and rake shaft?

link won't open, neither will the gear housing I wonder if I break one of those little plastic spacers on the auger shaft if that would allow the casing to open wider?

You need to pull the whole assembly out of the auger housing. This is done by first removing the large pulley. Then there are bolts on the side of the auger that hold the shaft in place. Once you take them, off, You can pull the whole assembly out. Then you need to take the shear pins out, and slide the rakes off. Mark the rakes so you know where they go when you reassemble. After the rakes are off, the gear case will split once you take out the bolts.

Man what a process. LOL Getting that pully screw out was interesting, not much working room. I don't look forward to trying to get it back in.

The auger and impeller are out, the case split, the broken gear removed. Everything in the housing cleaned up all shiny. All the parts laid out in order for reassembly. The new gear should be here by Thursday the 6th.

I wouldn't have gotten this far without all the help you have each given me. Thank you! I can see that I'm going to need some grease and some gasket sealer to put it back together. Any recommendations?

I should have Mentioned to separate the auger assembly from the chassis. Makes things much easier.
