到着に時間がかかる。
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。

Keep Craftman garage door opener alive if motor still working but internal plastic gear stripped.
Product comes with extra washers, helical gear, lubricant, cotter pins, in addition to main gear already mounted. No instructions included. A QR code printed on paper insert indicates that instructions available, however, it only brought up a website for garage door remotes. No instructions on product installation. On line videos on Google or U-tube is best option on installation. This not a drop in part and is more involved than suggested. Garage door opener was a legacy Craftman manufactured in 1991. Maybe newer models have simpler internal orientation, and their repair may be easier. Take into account drive chain needs to be taken off sprocket so give chain lots of slack before starting. 5/16 bolts x3 secure mounting plate to housing and need to be approached from within the opener(an articulating 1/4" socket wrench with extension helps). The mounting plate holes for these bolts need to be chased first with original bolts or threaded with tap and die otherwise it is almost impossible to screw in the bolts unless whole unit is on a backtable. That said, gearing fit perfectly in this aged opener and worked well on final assembly. Lubricate gears liberally before replacing cover back on. Make sure door travel is adjusted before put back in regular service. Quiet operation.

Excelente articulo, excelente relación calidad-precio.
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.
