View Full Version : thrift find! realistic sct-31..need help (belts)

Hey everyone, well went down to the local salvation army today and came across a realistic sct-31 tape deck..it powered on but no movement at all..ended up paying $4.00 for it. Took it home tonight, opened it up and the belts where broken off..the capstain one is also "glue" now...
just wondering where i can get a set of these belts? is it hard to install?

belts for various tape decks can be found online. I had to replace them in a Pioneer deck that i own. I can't speak for that specific model but putting belts on can be tricky and definitely requires patients (small fingers help too) If i remember correctly i bought my belts from here: http://www.turntableneedles.com/ a few years ago.

Draycos...took a look on the site but didn't find my tape deck...i think it had 4 belts in there....there is not much info on this deck, making it harder to find the belts...

i have done a little poking around before i turn in for the night and you are right, it does seem to be a harder to find deck. This site: http://www.vintage-electronics.cc/realistickits.html has the belts for a SCT-30. I wonder if the models are close enough to work (sorry, i don't know much about either deck)
There is also the option of buying a set of common sizes of the same belt type (flat, square, etc...) and seeing if one will fit. I found a "universal" belt kit here: http://www.studiosoundelectronics.com/cassette.htm#BELT (about halfway down) that claims to have the common sizes of square or flat belts. Perhaps one could be the size you are looking for? If there is still a belt left in the deck (even if it snapped) then you could get a rough estimate on the length, or just try different ones until you get one in that fits.
Sorry if this was overly long and that i cannot offer much help other than guessing belt sizes. Perhaps someone more familiar with that model deck will come along and be able to point you in the right direction.

Radio Shack did not make their own decks, instead other manufacturers made them. I wonder if the SCT 31 was made by Hitachi?

I used the generic kit from Studio sound also. I've also used Ken's Electronics, but you have to know your size, or close to it. No affiliation.

Hi guys, i'm stuck n this one as most of the belts have broken up in different spots of completly melted away....would another realistic model decks' belts work on my machine? i think i have 4 belts...

hi everyone..well i took some pics of my deck...wanted to know if any of you might be able to help me out in determining how many belts this thing might take (i'm guessing 4)...and if you have a realistic tape deck with the same layout, let me know what model deck you have..thanks
oh ya! what do you recommend (cleaning product) to really clean and shine this puppy up? thanks

well, I did many a deck and what I do is remove the whole cassette block. Take pictures before. Carefully remove the capstan wheel and clean metal parts with acetone. Clean all other plastic parts with denatured alcohol. Re-lube and reassemble.
One thing you can do when all else fails in determining the size of the belts is to wrap and tie a string around and then measure it. This will at least determine the best belt size from a kit.

Just last week I replaced the three belts on my SCT-33. Got the kit from vintage-electronics.net, which had them for that specific model. If they don't have your model listed, email them and they can probably put something together for you.
As for removing the gunk, I just used rubbing alcohol, Q-Tips, cotton swabs, Kleenex, and a lot of patience.
Actually installing the belts is not the hard part, especially if the gunk trail tells you where to go. Only take it apart enough to clean and replace the belts. Remember that one of the belts is for the counter.
Don't go crazy taking it apart more than you need to. I also found it helpful to put the screws on a sheet of paper mapped to where the came from. Made putting it together again a breeze.

goldwax. Good idea of the screws placed on paper mapping where they go. I remember doing this when rebuilding auto engine. Cardboard with rods and such labeled and put in the holes. I remember getting confused on some screws especially when there are different thread pitch sizes and where do they go.
You are right I think in that maybe if that's all op has to do is replace the belts, then taking it all apart isn't a good idea like I said.
I hope you can find the right belts.

Well, on some decks you have to take the entire transport apart... I wouldn't consider that easy. This one looks pretty harmless though, especially compared to Technics decks of that vintage.

Hi guys, i think the one i'm a little worried about is the big one that goes on the capstain flywheel...how do you get that one on? thanks

UPDATE...well i finally got the belts from a good friend of mine (Jorge) that was so kinda as to order and send me some new belts....after a good cleanup this thing sounds really nice..one of the best tape decks i've listened to. It's also a 3 head TD...not sure what that means though, but i like the way it sounds..
the only thing i have left to do is how to figure out how to clean out the push-down buttons...they seem a little tinged and have some small green spots on them..any ideas? thanks

I just acquired an SCT-31 tape deck that needs belts. Fabchef, is there a chance that you can find out which belts your friend ordered and where from? Also, would it be possible to shoot a pic of the transport mechanism so I can be sure of the belt routing? This is my first attempt at repairing a cassette deck and I would really like to get it running. Thanks for any help.

I would suggest trying mars communications.
