Darryl,
Now that you have the cam plate out on the bench,take off the large nut in the center of the plate and lift off the cam plate of the shaft, undo the three screws and take off the small cover plate that covers the bearing check that for any loose play, you can buy them at any bearing shop for a few dollars, tap off the cam plate from the shaft and place one or two washers on the shoulder of the shaft then reinstall the cam plate, that should then give you enough clearance to clear the surround that the cam plate is bolted to on the floor,also before you reinstall the plate check the clevis bar for play and if its to sloppy replace the pin or rebore the pin hole and fit an oversize pin to take up the slack,
Good luck Regards Ron
