4. Remove the switch from in front of the motor assembly. Remove the 2 long and 1 short screw holding the motor in place. Remove the motor. Degrease the outside.
Remove the 4 screws holding the gear box together and open the gear box. MAKE A NOTE AS TO WHERE EACH GEAR GOES.
Thoroughly degrease the gears and the box. Mine had dirt in it as well... Re-lube (I used Shooter's Grease) and reassemble.

Clean every pivot point you can find on every plastic arm in the lower section. Make sure they move freely.
Reinstall the motor, reinstall the switch. Make sure the metal arm that sits under the switch is making contact with the part of the motor lever gear closest to the body of the gearbox. It will try to ride on top of that part of the gear lever. Spin the motor lever by hand and it will pop down into place.
5. THIS IS THE TOUGHEST PART. Remove the arms connected to the solenoids by removing the E clips and taking them up and off. The one on the bottom solenoid comes right out. The spring will prevent you from easily setting it on the workbench so just lay it off to the side. after you degrease it and make sure it will pivot smoothly on the shaft.
The one on the top has 2 springs connected that prevent its easy removal. Degrease it, check its movement then set it to the side.
This will expose a black toothed gear. To the right of it is a big wedge shaped toothed gear. Remove the wedge shaped gear, degrease it (and the shaft of course) then degrease (but do not remove) the black toothed gear. Degrease under it well too. Use the spray tube on the brake cleaner for this. DO NOT REMOVE THE GLUE HOLDING THE NUT IN PLACE IN THE MIDDLE OF THE BLACK GEAR. Put the grey one back and make sure it pivots properly. Don't forget to reinstall the E-clip.
There is a short and long arrow on the black gear and an arrow on the wedge gear. Line up the long arrow with the arrow on the wedge gear. Hold this in place with one hand while you put the arms back on the top solenoid then the arms on the bottom solenoid. Reinstall the E-clips.
6. Turn it over and clean/degrease the arms over the top of the red price selector. Remove the screw in the middle of the price selector and take it apart. You'll have to bend a couple of the plastic arms a bit to get it out. As long as they aren't brittle you'll have no problems with this.
Degrease all the parts well.
When you remove the price disk this will expose the ball bearings it pivots on. Clean/degrease them VERY well then lubricate them with the Shooter's grease.
Reassemble the pricing gear and set the price to the desired cost for a soda.
Reinstall the coin guides/switches. There's a little nub sticking out of the top of the bottom section which you must place into the guide when sliding it into place.
The brake cleaner makes the surfaces cold which attracts moisture from the air. Be sure to dry thoroughly before reassembling.
Reinstall the coin tubes.
Reinstall the coin guides for the rejected coins.
Insert the coin accept/reject mechanism.
Put it back in the machine and test!
