Place a 7/16" open end wrench on the square end. Rotate about 1/4 turn until the spring releases and snaps the nut ring against the trolley (Figure C).

By hand, thread the spring trolley nut on the threaded shaft until it is finger tight against the trolley (Figure A). Do not use any tools.

Insert a screwdriver tip into one of the nut ring slots and brace it firmly against the trolley (Figure B).
