How tight is the gearbox? I find my electrics get hotter (not dangerously hot, just another 5-10 degrees) If I clamp the three main screws down too tight. Just half a turn allows it to spin much more smoothly.
And how hot are they 70? 80? 90? Thermal shut off?
I get up to 65-75 ish. That gives me another 20 degrees before the cut off.
