Do the Q128C and Q128H use same gears for 36V 328RPM builds?

Q128C and Q128H motors use the same gears for 36V 328RPM?
I'm running my Q128C (rated for 500W) at 600watts and does not even break a sweat (or so it seems).
Motor does not even get warm after a few miles at full throttle.
If it uses the same gears as the 800W Q128H, can I safely assume that gear failure would not be of concern?

It’s not much help, but I ran a q128c at 20a for over 300 Miles and it never once got warm.

I did mostly use PAS but was sometimes using the throttle and hitting 1000w to it.

I burned my Q128C at 48volt 18a up a long steep hil where I have used Bafang bpm and Bafang swx02 and Mxus xf18 without any problems.I also have used a Q128H (same no load speed) at 48v 18a up a steeper/longer hil with no problems

Thanks 1boris.
"burned" as in fried the motor's windings? Or did the gears give out?

Havent opened it yet but smelled like fried windings
