Motor gears stripped

One plastic is the same. Here a pic from July 2017

Whats inside the gearbox/motor?

So following in the footsteps of our patron saints AvE & Dave Jones, I took apart my gear box to see what secrets it held inside. Here is what I have found… [image][image] The gearbox (from my counting) as a 23:1 ratio from the motor output to output shaft. Both ends of the output shaft ride on a shielded bearing. Most of the gears are powdered metal with the exception of the worm shaft(motor output, single toothed, brass?) and the worm wheel (plastic). Each gear is held in place with steel …

Edit:
From March (that looks like the same gear failed)

Motor Gear failure?

Hi All. Recently one of the motor gear have failed [20180327_194354] The teeth of the gear got chewed off. Have anyone seen the same issue? Is there a way to just buy just gear somewhere? everything else seem like in a good condition. This assembly have less then 5 hours run time on it. I went ahead and ordered a replacement for the whole assembly, but im concern about if the same gear will fail again. Thanks
