Hi Leo

Leo don't feel bad but your saw also has the nylon gear, i'm sure, but
they sit on the inside, the electric motor has a steel shaft with a warm
gear machined on the end, the nylon gear runs on the steel warm gear and
the chain sprocket is on that same shaft on the outside of the housing,
if you do not force the saw the whole assembly last for a while but will
get stripped eventually, my advise to you is keep the chain sharp and
don't force the saw and you will get maximum life out of it, I got a
couple of those saws and one in use, the others have stripped nylon
gears, never got a price on a replacement gear so I don't know if it is
a good idea to replace the gears.
Hope this does not ruin your day

The other Leo
Have fun and take care

Bill, this is deja vu all over again. As I recall, the plastic gear that
broke on your saws is actually the spocket that drives the chain. My
electric saw is very much like the ones that failed you, except that it has
a steel drive sprocket. I have not had any problem.

So, my advice is: if you don't want to spend the big bucks for a Stihl or
Milwaukee electric saw, buy one of the cheaper ones, but make sure it has a
steel drive sprocket.

I do envy you with an electric Stihl saw, though.
