bucket removal 580k

so i need to put in a missing bushing on the dipper arm / and another missing bushing on the bucket itself / so is there a procedure to drop the bucket that most efficient / i got that part on the end that has the quick hook to pin ./or is it called a qui ck coupler

so if im correct lay the flat of the bucket on level surface / pull the one pin off then move the arm so it unhooks from pin #2 ???
