Alex,
What size shrink tube did you use for your 10ga wires in the motor where they go past the axle?

Thanks Allex, I will do a lot more research "natural" air pumping before trying to bend a cast alum side cover to create a subtle blade. If I try it.Allex said:Emmet, I would not do this as the Aluminium is very porous and brittle. Especially low quality moulds that comes from chinese motors.
Here is an interesting Post, the fins looks like the ticket for a good Passive cooling.

Well, I read many threads on cooling. I was wrong about drilling vent holes at an angle to pump air flow. I know what I need to try now, for my specific needs. No air venting, since that's impractical for decent motor life where I ride. Sealed H4065 hub (with small breather near the sprocket). 120ml of ATF inside, to transfer stator heat more quickly to the external surfaces. super quick easy mod. Maybe I'll carry a small water mist bottle in my back pack. Shall see. Thanks again for telling me about those cooling threads.Emmett said:When modifying the hub cover to function as a gentle rotating fan, I can imagine that simply angling any drilled holes might to assist air flow significantly. The lightest pumping air flow has to be way better than relying on slow air mixing/diffusion.
Allex said:Nice, let us know how it goes!
i assume you are afraid to get water and dust into the motor. the same reason why i keep my motor closed AND sealed up.Allex said:I handed over my covers for drilling, but not really sure if I still want to do that...
