OK Well apparently this VCR has more wrong with it than just belts because I just installed the new belts and the VCR still refuses to play (it will load the tape into the player but then it sits for a few seconds and then loads the tape back into the tape housing again) the supply reel turns just fine but the take up reel (which I thought that replacing the belts for it would fix it) absolutely refuses to budge which is why the VCR refuses to play, also the F.Forward and REW. functions still don't work all they do is make the solenoids for the functions click and that's it, it doesn't actually trigger the mechanism like it should, so there's clearly something else in this VCR that's gone bad or isn't functioning correctly that's causing this VCR not to work properly, but I'm not sure what it is.

Any ideas as to what else could of failed in this VCR to be causing the no play issue and the no F. Forward and Rew. Function issues? I know it can't be the idler assembly as the idler tire on this VCR has no rubber tire on it (its just a piece of round ribbed plastic) and I don't think its the solenoids because they all are functional (they all click like they're supposed to when they're triggered letting you know that they're getting juice/signal from the buttons). Is there some sort of component that was known to go bad in this VCR that would cause these symptoms and if so would it be a simple repair?

UPDATE: I finally got the rewind and Fast Forward to activate like its supposed to, but its still doesn't want to play the tape though, it'll load the tape no problem but that's about as far as it gets before the mechanism gives up and reloads the tape back into the cassette.
The other issue I've noticed now that I've got the Rewind and Fast Forward going is that the fast forward goes at its proper speed, but when you go to rewind the tape barely moves and I'm not sure what's causing that issue.
Also I had noticed previously that a winged worm-gear had fallen out of the cabinet (like one of those winged worm-gears that is used to govern music box mechanisms) and anywas at first I thought it was something that didn't belong in there but then after closer inspection of the VCR Mechanism I noticed a small gearbox assembly on the bottom of the VCR mechanism that had small clockwork style gears in it that I saw an area in the mechanism that was where that little winged worm-gear went into the mechanism so I reinstalled the gear but of course it seems that the little clockwork mechanism doesn't seem to do anything for the VCR that's super obvious (although after I repaired that clockwork mechanism that was when the rewind and fast forward functions started to work again).

So does anyone know what the little clockwork mechanism does in this VCR?
Also does anyone know why the Rewind function would move super slow while the Fast Forward function works perfectly fine, and why the VCR still wont play a tape?

EDIT: I figured out why it isn't playing tapes, there seems to be an idler tire that goes between this large Drum style motor on the underside of the VCR Mechanism that is supposed to then go and drive a brass "tire" that in turn would drive the take-up reel (See attached photos) but that idler tire under the VCR Mehanism seems to be broken around the inside diameter and because of that the idler tire can't drive the take-up reel properly. Where might I find the aforementioned idler tire? Would some place like SMC Electronics have it? and if so how much? Also I noticed that the large brass capstan roller inside the VCR Mechanism (see pictures) has a small round plastic ring on the top of it that seems to of broken off or something and I was wondering how critical to this VCR's functionality that piece is, if its not would it be ok to remove that piece of plastic out of there so it doesn't disturb the playing of the VCR?
