When the needle comes down

Question

When the needle comes down and enters thestitch plate, the needle strikes the hook or hook race cover and bends to the left. When I was sewing, the locking lever that holds the hook race cover in place vvibrated loose and the hook and race fell out. When I put everyting back and snapped it in place, it is like the timing of the needle position and the roatation of the hook are not in sinc any more. Can this be fixed?
