This came in augers not turning. Took it apart and the gearbox is dickered. The worm gear was chewed up, all of the hardware where the impeller shaft enters the gearbox was all chewed up, needle bearing and such. And the gearbox itself was kind of screwed where the impeller shaft enters. It's kind of oblong. Since a lot of the parts are either super expensive or discontinued, I was thinking of search for some used stuff. But I'm having trouble figuring out if the impeller shaft is still any good. There's like a recess on it, like a throat part about where it would sit as it entered the gearbox. Not sure if it's wear or designed that way. I included a link to a photo. Shoes were all worn down on this and the scraper bar was gone. The auger was hitting the ground and the shear pins were way too tight. Guessing that's why the gearbox took such a beating.
