Perfect fit, lube gears install and minor adjustment on door travel, door works great

Worked perfectly, I would recommend this as fit was perfect and only took about 30 minutes to install.

The kit was cheap, arrived quickly and worked as advertised. I was fixing a broken shaft issue that I didn’t understand until I opened the unit, after the kit arrived. I only used the main part and the grease but the kit has everything to rebuild unit (outside of the motor). Some reviews recommend a tap and die for the mount holes. 1 of the 3 were crooked but that is far from critical, in my opinion.

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! Delivered quickly! Great experience overall.

予定到着日より１０日以上遅れて到着しましたが、無事配送されました。 取り付けのねじ部がタップが切られていませんでした。 なお、ネジはインチネジ （元と同じですが）でISO規格ではないので注意が必要。

Everything worked out. Repair was easy and parts for as they should.

te ahorra mucho dinero al tener esta pieza como repuesto, se mira de la misma calidad que la original , ahora hay que probar cuanto dura...

El producto cumple con las expectativas requeridas, un poco complicado de reemplazar por la parte que originalmente se daño, pero con un poco de paciencia, quedo mejor de lo esperado. Viene con los reemplazos necesarios para hacer la correcta colocación. En caso que no tengan la paciencia para el cambiarlo es recomendable contratar a personal especializado, ya que en algunos momentos si es tedioso estar maniobrando en las alturas (donde comúnmente se encuentran los motores), ademas que si requiere sapiencia el ajustar los máximos de apertura y cierre.

Relatively easy to install with online videos as support. Works well, but still noisy. Think I might need to change the chain.
