Replacing Bucket Teeth on my Cat 941 Traxcavator

In this video, I am replacing the teeth on the bucket of my Caterpillar 941 Traxcavator. The old teeth were worn and one of the teeth was substantially shorter than the others. There's not enough room for a full swing of the hammer between the teeth. So, it seems like I was just tapping a few. I had to cut off the last tooth before I could get it's pin to budge.
