To remove the cover, unscrew the four nuts from the cover attaching studs (see Figure No. 1), reverse two of the nuts so the washers face outward and
screw them back onto the inner two studs. Assemble the two remaining nuts to the same two inner studs with washers facing inward. Using a small
wrench on the inner nut, on each stud, jam the two nuts tightly together. Again using the small wrench, on the inner nut, unscrew the studs until the cover
breaks loose.
