Simplicity auger shaft ?

I have a Simplicity I75246E snowblower. I was using it today and the auger drive belt came off. When I went to put the belt back on the pulley, I noticed that there was about 1/2" of play in the pulley. By this, I mean that I can move the whole assembly (pulley, impeller, and shaft to auger gear box) back to front horizontally a good 1/2". The worm shaft actually slides in/out of the auger gear box. All of the bolts seem to be tight. The belt/pulley has worn a small groove in the plastic belt cover, so I'm assuming that something is worn or broken. Any suggestions on what parts or adjustments I should be looking at? Sorry if my terminology and descriptions are confusing. I'm mechanically inclined, but have very limited experience with snowblowers. Thanks

I was going to use the quote feature, but it looked more complicated than I was up for, so I'll answer your statements in order. It looks like only the right side case had the flat for the bushing, which is gone now. Thanks, I would have missed that. Adding a new R side case to my order list. There was a little grease on the gears, but the bulk of it was pooled in the bottom of the case. Temps of -30 to -40F are not uncommon here. It just seemed stiff even in my unheated garage which is warmer than outside temp. I'll see if I can order some L3. Is the Snapper 1704636 worm gear oil similar? Just curious because the place I'm thinking about ordering from (Norwalk PEC) lists the snapper lube but not the ariens. What exactly should the worm gear tooth profile be? Should the top of the tooth be flat or have a slight saddle where the worm drive contacts it? It looks like the pin is fine but the thrust collar definitely has scoring on it from rubbing on the now flangeless bushing. Another collar on the order too. Are the collar pins re-usable? According to the diagram, it is part #936098. I can find part #2936098 that crosses to part #2836098 but I'm not sure if they are all the same part or not. I appreciate the help. My order list keeps growing, but hopefully you are saving me the time & effort of more than one tear down.

>>>There was a little grease on the gears, but the bulk of it was pooled in the bottom of the case. Temps of -30 to -40F are not uncommon here. It just seemed stiff even in my unheated garage which is warmer than outside temp. I'll see if I can order some L3. Is the Snapper 1704636 worm gear oil similar? Synthetic 75W-140 GL5 MT-1 hypoid gear oil is -50 capable. L3 is synthetic 75W-140 GL5. The Snapper lub is “cold weather”, synthetic oil and probably 75W-140 GL5 also. Ariens is ok and the Snapper also. >>>What exactly should the worm gear tooth profile be? Should the top of the tooth be flat or have a slight saddle where the worm drive contacts it? There is a slight concave run on the top of teeth. The wear is indicated by the thickness of the concave flat on the top of the teeth. The tops should be smooth and unscratched.
>>>It looks like the pin is fine but the thrust collar definitely has scoring on it from rubbing on the now flangeless bushing. The collar is pinned to the shaft which with good parts has slight front to back movement. I’m not sure about collar contact with the flange surface. The worm is on the top of the gear and pulling forward as it moves the gear so probably no contact between flange and collar under load. You’ve ordered a collar so no issue.
>>Are the collar pins re-usable? Unless you took a hit I’d re-use it. The pin is 3/16 x 1 ½ so you can pick that up locally.
