FWIW

Not pushing down... just the weight of the drill. The priming tool is the type with the valley collar, which I believe would prevent any undue downward pressure on the drive shaft. The drive shaft does not turn smoothly... if I stick a screwdriver on it and turn it slowly by hand, I can feel the shaft kinda jerking in steps rather than being buttery smooth. No other symptoms. I'm starting to think maybe it's normal, but I was just expecting the shaft to turn smoothly.
