A giant step forward. Oh, it's not the auger pins that are an issue, I replaced them last year or the year before when one snapped. Fortunately it was on the side that didn't have a nolt in it. I guess the guy before me sheared one off and replaced it with a bolt. I got four, two to replace the snapped one and the bolt and two for reserve. They were easy.
The ones I'm working on are for the impeller. Tight space and no way to see them without a mirror and a flashlight. Right after I posted, I went out with my phone and looked to see if I could set it in there some way with a video as I posted before. As I was looking at it, I saw what looked like a break in the shaft, maybe a 1/16 or 1/32" in front of the impeller. I snapped a picture and took a look and it was definitely not shaft and about half an inch from the impeller hole.
I grabbed the impeller, twisting and pulled on it. It took a bit of elbow crease but it finally pulled toward me. I got it this close-
It was nearing freezing and the light was getting lower so I stopped and will go at it on the weekend since it's supposed to get close to 60. I want to mark the shaft with something like fingernail polish where the hole is, turn the shaft so I can align it so I can but the 3/8" steel bar I bought to insert into the chute hole to drive the old roll pins out and put the new ones in. My expectations are about 95% higher rthan my last post.
