I'm running small indoor track lots of stop and go. I added washer to slipper plate so can clamp it down good but I notice that if I compress spring completely it Bends the spur shaft and when I turn tires be hand I can see it
then I saw that the belt actually goes up and down just a hair but. This might be where heat is coming from maybe spur had run runout causing a bind with pinion ? Just thinking out load any help or advice thanks..
