Wolffman, I will give you a little idea on the installation and removal of cover plates. On the first installation of them it is best to remove the concaves from the machine to place a holding bracket on the right side. The small flat plate that holds the wires in is replaced with this bracket. Second, once you have the bracket on....you remove one of the 3_8" bolts from the left side to hold the cover plate on by the concave extentions. Third, and last you install a 1_4" small "J" bolt that holds the cover plate up in the middle for operation. This J bolt has a wing nut on the bottom and the J part hooks on a wire. Removal is easier than installing. You turn the wing nut loose and have to rotate it a quarter turn to get it off the wire and then you loosen the 3_8" bolt on the left side and remove. There will be thrash in the wires after you remove the cover plates, but it will come out in less than a minute the next time you go harvesting again. Hope this helps. Jack
