I'm replacing the clutch in my John Deere 1050 4wd tractor. I ordered a new clutch from Yesterday's Tractors and now I need to adjust the clutch fingers, or the clutch release lever height. The manual specifies a special tool, a JDG-52 Clutch adjusting tool. In the photo below "A" is the special tool and "B" are the clutch fingers that need adjusting. The two local John Deere places do not have this tool, don't know where to get one, and the wait time on an order might be three months. I've looked around on the internet and can't find one except a sold one on Ebay. The clearance that this gauge is set for is NOT in the manual. So I've hit a brick wall here. Does anyone have any insight on how to set the finger height, or where to obtain the tool? Thanks!
