Pete,
I've sent this a couple of times and not sure if it is getting through...I see where part of it posted to the forum.... sending to a couple of e-mail address hopefully will get though...
The encoder pulley is situated between the Wheel and the motor. The belt is a double sided timing belt. The pulley is .7" in diameter. The encoder pulley is in the drive belt loop between the wheel pulley and the motor pulley
Thanks for the help
