I'm trying to get the chain sprocket out of the tine shaft on a 30" JD mechanical tiller. The sprocket and its shaft will spin on the tine shaft and slightly move out but will not pull further than 1/4 inch. I don't see a way to get in back of the sprocket to either pull it or push it out. Anyone ever do anything similar? Am I overlooking something obvious?

You don’t happen to have a piece of the cross drive bolt still in there? And or the hole may have a “burr” from the bolt hammering on the shaft, I’d try to align the holes to be sure the hole is clear, then I’d cut some wooden wedges to hammer on each side behind the sprocket to bring it out
The bolts are out. I think it has to be a burr in between the chain sprocket shaft and the tiller shaft and probably came from one of the two bolts securing the chain sprocket to the tiller shaft. I had thought about the idea of making a few wooden wedges but did not try it yet. I also considered constructing something that would enable using a 3 jaw puller on the sprocket. I just stopped on it before I did something stupid to just kind of calm down a little. That sort of things gets on your nerves after awhile. If I make something that works out in pulling it off I'll try to remember to post a photo.
