Neu 1515 & MMM Temp Poll

may i ask what gearing are you running?

Check the bearings on the motor, bad bearings can cause high temperatures and it seems like the bearings Neu uses isn´t that good, I´ve heard of several neu´s with bad bearings

i have another thread going about how to open up this motor. i've been curious about just that. i might as well swap out the bearings when i do check them out. any recommendations?

i've been all over the place with 54, 56, 58, 62, 65 and 68T spurs along with 16, 18, 20, 22, 24, 26T pinions.
at the moment, i'm running 22/65, but after the fan job, i was getting ready to drop 26/62 back in.
again, didn't really see a difference in temps on the motor when changing gearing. only time i saw any difference at all was the MMM and batts got a little warmer on 26/56, like MMM =140*F and batts = 130*F.
