Removed the cap by pressing ion the sides tabs to release it from the spool housing, Then removed the old spool and spring. Before I did all of the removing of parts I put some replacement line on the new spool. Then I place the new spring in the new spool and let 4-5 inches of line out of the eyelet on the spool housing. Then lined up th e tabs of the new cap to the matching holes in the spool housing and press it in.
