Okay so I got the thing open and it takes my quarter and gives me the 5 nickles but the dime falls straight through to the change hole. I feel sure I can get it working if it's all complete but what I want to know is if it could be because it's missing something like a spring before I go through the trouble of taking the mech off. If needed I can make a video of its function or lack of one anyway.

Can you post a photo of the slug rejector?  I'll try to dig up some of mine to compare.  Update, photo attached, it's not mine but one I pulled from the web to compare.

If I remember correctly, mine had problems with dimes at first as well.  I pulled off the dime magnet (upper grey rectangle, next to the spring) and had to give it a light scuffing with sand paper to clear up the jams.  

I cant seem to get the picture to size to where I can post it and still be visible. I noticed today that a screw was missing at the bottom right that holds the arms in place and the the small arm keeps getting stuck behind the larger arm. Although I know it has nothing to do with the dime falling through. Looking back again at the mech and your photo I am missing the what looks like a bubble level at the top right. I guess I'm just going to have to take the mech off. I really don't like the idea of taking the screws out of that plastic piece.

        Do not remove any screws from that slug rejector.  It should come out easy for cleaning which will solve the dime problem.

        The upper magnet in the pic is riveted in and will not come off, but the lower one will and is the one that scans dimes.

        On all rejectors, remove and hold level above the table. Drop in the coin and follow it. If it sticks or gets diverted.....figure out why!

Sounds like you do not have the correct rejector. On an original VCC mechanism, there are no plastic pieces!
Four screws (two on each side) hold the rejector in place. Easy to remove.

I got the mech off before I got to your post. I knew about the screws the problem was one was behind the movement at the bottom. I figured out I could just pull the knob down a little to unscrew it. Anyway I cleaned it up and it still rejects the dime. The problem is right at the top, its not even making it to the magnet. There is one small brass piece at the top that is bent out (to the right of the spring at the top) I need to figure out how to get it bent back in. At this point its the only thing I know that could be the problem. Also is there a spring that suppose to be on the moving piece on the back area to the left of the bubble level? Thank you all for your continued help with this. It's really frustrating to pay for something that suppose to be working but doesn't. Oh and the plastic piece I was referring to is the block looking piece that moves with the arms at the bottom it has nothing to do with the coin acceptance. Whats an easy way to re-size these pictures to post them? It would be so much easier to explain things.

Check your PM's, I can resize for you to make it easier

I bought an ap for my phone that resizes my photos and I can post them pretty easy .

It's called image size . Works great

I think I got it to re-size thank you though tkaz. Lets see if it will be big enough.

Your blue arrow is the quarter oversize gauge and your red arrow is the quarter cradle. Both have very little to do with the dime path. Sounds like your main scavenger plate is bent. The MSP is the part that the cradle is mounted on.

It doesn't appear bent. Would such a small bent that you cant even see cause the dime to fall through and not the quarter? If it helps if I hold the cradle in one position while dropping a dime in it will fall through like normal. Of course the quarter gets stuck at the cradle so holding it in place somehow is out of the question. :darn:

When you drop the dime through, does it make it to the point indicated by the red arrow then get rejected or is it before that?  

Second pic, does the dime get stuck where the green arrow is?  If so, try moving the bar marked with the blue arrow all the way out and drop a dime through, does it work now?

I have drawn on tkaz's picture.
The curvy red line (on both pics) indicates the dime's path. The dime should be forced through the rejector main plate to the back side at the green oval.
On the back side, it rolls under the magnet and should miss the deflector and hit the separator. Your deflector is in the green oval. Loosen the deflector screw and move it all the way out in the direction of the arrow.

It is hard to tell from a pic, but it looks like your dime scavenger plate may be bent and that could an issue.

 :laugh: I wish I got that replay a couple hours ago. I figured out the path and what the problem's are though. tkaz post lead me to look at it differently. First off some A-hole took the spring off and one pin that holds the rod on at the red arrow. Of course never putting it back on. I'm screwed there. This was causing the plate to have play in it at the green arrow making the dime fall right out of the mech. Sometimes it would get jammed at the blue arrow. I noticed that (probably the same A-hole) took the spring off there and got it jammed under the magnet so the coin had nowhere to go. I got that spring back in place. I adjusted the screw on the back to put more pressure on the bottom, now I can get it to take a dime like 1 out of 15 times. If I push with my finger at the green arrow it will work every time. So now I have to find a spring that will work. I feel sure this is the problem. If you have any advice on how to correct this spring issue I would appreciate it. Thank you all for your help. I was on the verge of bashing this thing with a hammer and tossing it out.

Coming in a little late... but also make sure the two screws located by the green arrow are not too long because they will keep the dime path "open" due to the dime slipping through as the "triangular" guide those two screws fasten will be raised allowing the dimes to fall through at this point.
Not sure if this makes sense...

For Android users there Is a free one called 'reduce photo size'.  600X800 works great!

Yep it makes sense after looking back at my picture. It took me a second to get an angle so that I can see the back clearly but they are not sticking through at all. Thanks. Till I figure something out I guess I will be telling people hold you finger here while I insert a dime.

Oh just a little update here. I got it adjusted to the point where it will pass 90% of the time and jam the other 10%. Acceptable for me but now its rejecting here at my red arrow. The small moving piece at the blue arrow was stuck in place I pushed till it came loose. It still seems a little dirty/dragging feeling. I want to take the two screws out at the bottom so I can clean the track real good but its holding together multiple plates. Is it safe to remove those screws?

You will want to remove the nut/lockwasher & screw/brass washer from the front cover plate, then remove these two screws.

Okay so now the coin mech is working 100% now I got a new problem. On the left side the moving piece in the picture wants to move down on the left side (red arrow) and barely any on the right (blue arrow) which is causing the arm (green arrow) not to go up to reset what I think is something to slow down the coin. There is also a small spring like wire there that I have no idea the perpose of. I know on the window model there would be an extra arm on the left side but mine is an early model with no window. I cant find anything that would appear missing. I just cant figure it out.

That is the 'out of nickels' circuit.  When there aren't enough nickels in the hopper/chute (minimum of 5) that bar pushes down into the chute and moves the lever at your green arrow up to reject all coins that are inserted.  To reset, fill the hopper with coins and move the main lever several times to allow nickels to fill the chute, which will also reset that lever.

It looks correct to me. And to reiterate what Tkaz said....
The wire form linkage resets the coin deflector (green arrow). The plunger (red arrow) goes down when no nickels are present to give change making the deflector linkage inactive. When nickels are present, the linkage is forced to reset the deflector.

The three prongs of the deflector redirects coins to the right so that they are returned to the customer, the single tab of the defector is hit by an accepted coin forcing the three prong side in. When the handle is cranked down, the linkage resets the defector (or not) depending on whether coins are nickels in the track.

In a hurry, so I hope that makes sense....

Yep I'm late on this one. I work 3rd shift and haven't had much time or energy to put thought into it. I was just laying in bed trying to get an extra hour of sleep when it hit me that I had the nickel bucket empty. I put some nickels in and boom hitting right every time. I can smack myself. It never crossed my mind that it would still function the same even without a window. Now if I can just fix all the sticking issues it will be 100%. If I pull the handle to slow the handle will go back up but the block that holds the coin for vending will stay stuck out. Like the cam is slipping or something.

Mine was sticking as well when I got it, I pulled that part out (mine is a phenolic material) and gave that area a good scuff with some scotch brite.  There are two nuts on the outside that hold it in, just make sure you pay attention to the washers and how they are set in there.

That would probably work good for me unfortunately it isn't the only place its sticking. It's also the nickle shoot that I have no way of getting to. I might try some type of cleaner and see if that works.

Try rubbing alcohol (or other cleanser) and a stiff pipe cleaner along with compressed air. There are oiling points on the VCC mechanism, but the slug rejector and nickel track  should remain free of any oil.
Maybe this scan will be visible enough....
