X axis motor mount

The motor mount on the X axis (underneath the table) has slop when pushed back and forth in the Y axis. It's just the motor mount plate, not the table itself. Everything seems to be cutting ok, but I was under there greasing the pinon gear and noticed the movement. There seems to be a pivot bolt on one side of the mounting plate and another bolt on the other side that's attached to the adjustment mechanism on the right side of the table. Should these bolts be tightened after pinion gear to rack adjustment? Are there instructions on how to make this adjustment?
