I adjusted my clutch today and in doing so, I found that I have a crack in each side of the driving disk. Should this be replaced? and where is the best place to locate one of these?

George, I spent the winter working on the clutch of my JD "AO". I utilized a JD "B" Service Manual for general information (since Deere apparently never made an "A" Service Manual). The manual addresses the specific problem you are asking about. The manual states: "Examine driving disk for cracks. If cracks are small and do not extend into the hub, driving disk is serviceable. If cracks extend into the hub, replace driving disk." Your guess is as good as mine as to what "serviceable" means. Maybe it means you can just put back on or maybe you need to weld the cracks(?). I purchased a new drive disk for $230 (give or take)from Dengler's. I bought a 0.030" undersize to fit the worn splines of my crank. Dengler's is the only place that I know of to find an undersize disk. Deere sells it's standard size only and it's $350. Both undersize and standard are $230 from Dengler's and are supposedly made of a higher grade cast iron. Nick at Dengler's was very helpful. His number is (513) 423-0706. Remember to keep that disk tight on the crank to protect your splines. Good luck.

I personally would want to dig in and find out why that happened. Not only would I replace the cracked part, there had to have been a cause. There are several places to find used ones and the website of atis.net has a listing of salvage yards. You could ask a dealer to. Before you get one, might be worth looking at the other parts to make sure you have all you need at once. The way the cracks go would tend to tell some story as to what happened.
