Setting up a jointer question (pics inside)

On my Craftsman of 1978, the aluminum bar with the two hex head cap screws is loosened. I remove the screws. . The bar needs to drop down to release the tension on the blades. It’s most often jambed in REAL tight and requires a good rap or so with a hardwood block and hammer. Sometime I’ll take a large screwdriver and pry a little from the ends of the bar to get it to loosen. At any rate the screws under the blades only raise and lower the blades to proper height with that bar loose, the bar is wedge shaped and jams the blades tight against the roller when it’s tightened..
