So I picked up a JD 894 rake yesterday, (yeah, I've read some people don't like JD 894 rakes, I got it cheap) and I've got a couple of questions concerning the bearing and sprocket that drives the reel. The sprocket is really worn, and from what I've gathered, it's doubtful that JD is going to have that part. Same with the bearing. The bearing I imagine I can probably find somewhere else with the same dimensions. The sprocket though would seem to be harder to find since half of the universal joint attaches to it. Would a machine shop be able to build up the sprocket teeth? I can probably flip it to the side with less wear for a while if need be. The shaft that the bearing is on has been worn down a bit as well, could that be built back up also?? The bearing seized so it spun on the shaft a bit. Other than a little slop in the axle on the right side, (which I can fix with some washers) the rake will be ready for the field once I get the sprocket and bearing problems resolved.
