Hi Richard. I got the idea to take the side cover off from a guy that had a Gravely shop. I was previously told by another shop that the engine had to come off & the transmission removed. I opted for this method & so far it seems like the way to go. There were only 4 washers that I noticed. Two of them, that you notice in the picture were right near the place they came from. One other never came off of the shaft it was on & the other one toward the bottom of the case is a smaller diameter & can only fit over one shaft. I have all four placed on the shafts now. My parts breakdown doesn't even show the washers. Are there any more that you know of? As for the woodruff key, The only one that I see is on the gear that fits inside the clutch hub and that has be together before the before the cover goes on. I planned on getting the service manual but didn't order the parts from the place that had it so I am winging it with the help of the internet. I may have to use a wire with a hook on it to get some of the shafts to fit in their respective places as I slide the cover back on. Feel free to offer any suggestions. Clutch hub should be delivered this evening----Ron
