This kit worked perfectly for an old Sears Craftsman 1/2 hp 41A4315-7A model opener.I think the counterweight spring gets looser over 20+ years! And this wears on the nylon gear because the motor and gear are constantly doing more work.My opener was also adjusted to try to push the door too far into the concrete floor! (which always caused the track to bow upward at the end of closing), and the opening and closing FORCE was set higher than needed. All these must have combined to finally cause that nylon gear to fail.> I loved ACVOCE's video here on Amazon 10:21 showing many items to consider while replacing the gear. One additional thing: The tiny gears at the bottom: the one that stays on the opener- if it gets turned it changes the door stop locations, both top and bottom, so I marked it with a pen.Like his video shows how to thread the 3 holes on the new part! Luckily the opener had self tapping screws. TIP: put a drop of wd40 on each of the 3 new holes, then drive an old screw into the hole with a drill just like the video and you have 3 tapped screw holes in 3 minutes or less.> My wide garage door has 2 coil springs that you rotate to tighten. I learned a lot of youtube and carefully tightened each spring 1/2-3/4 turns so that the door would stay open half way up and not fall down. (When you disconnect the carriage from the opener by pulling the red handle)> I lubed my track and chain- why not. (took 5 min)> I reduced my up and down FORCE adjustments 1/2-1 turn, and it works great while protecting the opener from wear.> I adjusted end points to fully open the door, and fully close but not push forcefully into the floor. (just takes 1-2 min)

Worked perfectly. Took about an hour to put in. Big note is to figure out where the door is supposed to be, up or down before hooking up the chain or belt. Watch YouTube first and you'll be fine
