Belts/Pulley - Connecting the Motors to the Wheels

Small XL (1/5 Pitch) Pulley - 10 Tooth

9" XL (1/5 Pitch) Pulley - 45 Tooth

Large XL (1/5 Pitch) Pulley - 30 Tooth
I ordered all the pulleys online, the big one off Ebay and the small one off Servocity.com. I got the 9" belts from a McGuire bearing which were surprisingly cheaper than online. The small pulley has to be bored out to 8mm (about 5/16") from 1/4" to fit the motor shaft. The motor shaft will have to be notched to for the set screw in the small pulley. The large pulley will need to be bored out to about 1" to clear the 3/4" truck axle. Then holes drilled and tapped for mounting to the wheels.
