Can anyone help me find gears, chains or other transmission parts to use with this motor?

Buy a plastic gear from anywhere that has hole diameter less than the motor shaft diameter. Grind two opposite flats on the motor shaft about .025" deep and drill a hole in the plastic gear about 015" undersize for a press fit on the motor shaft.

Will it work with only a 6v dc input?

Yes. I used a variable voltage dc power supply to change the rpms up or down. Runs fine from 3-12volt input.

What is the amp draw?

Robert, I don't know the exact draw because i don't have the motor available but I am using a AC Adapter For Magellan Roadmate 1700-MU GPS AN0204SWXXX Power Supply Charger to power the motor.

Is this motor reversible?

Yes, just reverse the polarity. It's an amazing little motor!
