I did check the motor from the front panel setup. Every time I hit the soda selector button , the oscillator turns left and them right but then the oscillator bar comes to a stop bang in the middle preventing me from placing the soda cans. I put them on top of the bar and then hit the selector button the cans do drop in and load the oscillator but every now and then it has a tendency not to dispense a can.
The motor is definitely working. I'll have a look see tommorow to see if I can take the motor out. I thought there would be an easier adjustment than taking the whole motor out. Thanks for the input

Ok figured it out. Those metal shims go on the side with the wide square end going vertical on each side of the column. Then you stack the cans and voila they dispense. That was'nt too hard! Now I need to figure out why those tube lights are not working! Thanks for all the help

the dixie narco website did provide some help. I did not see any directions on the inner door except for programming the control board. I am going to check the settings for the cam ( i think i know how to do it!)
the thing that is throwing me off is these shims. I cannot understand the purpose or how to install these shims. when i take the shims out the oscillator bar rotates but it should stop in either and extreme left or right position so that i can load the cans. instead it just stops in the middle. i'm going to see what happens and will update you all. Thanks for all the guidance and hopefully i can get to work on fixing cars after i figure this out!

Hi Ven1ng, thanks for the reply. I believe its 3 can deep because that's how we filled the 4 columns next to it. Ok so these side shims go on the side and not flat like they are pictured? I'll try this and see what happens. There are two shims in the column and each shim has an edge to it. When we put the shim on the side does the edge face up or face down? I'll keep my soda cans crossed!
