I installed my speed changer on one of my ERs today, with the original size belts that came with it. I sprayed the belts with dressing prior to installing. Installed according to the SS original instructions since these were original belts.
After running for about 5 minutes, no load, the bottom of the motor is hot to the right of the vents as you stand on the switch side, but not too hot that you cant leave your hand on it for a minute, other side of the vents is ambient, bearings are ambient temp. Top of the motor is ambient.
The knob that holds the SC cluster/sheaves on the SC is warmer then ambient.
B4 installing I greased the SC sheave shaft with SS grease. All turned free and center sheave moves easily on it shaft laterally. All 3 pulley faces are even when I set a straight edge across them, belt tension is at SS specs, belts are 90* to pulleys.
Is this normal? Never paid attention to the motor temp B4 I installed the SC so dont know if it was running these temps prior.
Now back to the Packer game, and up coming victory, half time, B back here after, for a night cap.

As long as you are saying 'warm' rather than 'hot', I would not worry.

Well at the end of the 3rd quarter it already certains for the Raiders!!!
I went over the original SS trouble shooting guide, they mention the "beveled side of the sheave knob should be against the bearing, both sides are beveled the same, and when on snug, it is just off the bearing, flipped it and the same. Ran it for a few minutes and the motor was not as warm as this afternoon. May have been just normal.
Tomorrow I will take off the SC sheaves/pulley and run just the single belt and see if the motor is the same.
BTW, with the speed changer on I have it set up for low speed operation.

Realize there is some power loss in the SC.






Guess where it goes!;)

Like most mechanical and electric waste, heat!!!!!
