akai 4000db reel to reel

shipped in storage unit from oregon to florida.Unit fell 3 to 4 ft in transit inside storage container.took it apart and the only thing that seems out of sorts is the pause/start button mechanism.the start button is riveted to a curved shaped plate and just seems to be kind of dangling.when i put it the face plate back on it seems that the pause/start mechanism is grinding against faceplate.i downloaded service manual but couldn't tell if anything was missing.I can try and get by with it but it just doesn't seem right.any help would be appreciated
