Can't get the belt back on

Lift the rubber cover off- there should be an opening or two in the metal or plastic turntable platter. Rotate it slowly until you see the motor pulley sticking-up; use a nail file to gently pull the belt from the bottom of the turntable over the pulley. rotate slowly to verify and then put the rubber cover back on. Let me know how it goes. Thanks.

1. Remove the rubber disc from the metal platter.
2. Remove the metal platter by pulling straight up.
3. Ignore the player for the moment; focus on the platter.
4. On the underside of the platter is a circle about 2 inches smaller than the platter; stretch the belt around that inner circle. Make sure it is not twisted.
5. Put the platter back on the player. Rotate the platter so that one of the rectangular holes reveals the drive wheel.
6. Stretch the belt so that it goes around the drive wheel (I used a pencil but tweezers would likely work well).
7. Replace the rubber disc.

What's likely is that the belt that drives the turntable has snapped. The MC-715 is a mid-late 80's model, so the rubber the belt is made of has had it. A google search for mc-715 belt will turn up a source for a new belt, which you can install fairly easily. There should (though it may be missing) be a hub in center of the platter that you turn to allow playback of 45's. This is removable, simply fit a flathead screwdriver into the side where the raised lines are and pry it away. If it's already missing, then don't worry about it.

You should now see the spindle (silver metal axle/pole that the platter revolves around). At the base of the spindle there will be a black metal circlip. This holds the platter down, and it will have to be removed. Use the flathead screwdriver again to pry it off. You should be able to do this by putting the tip of the screwdriver into one of the two openings on the circlip and using a twisting/prying motion. Once this is off, simply lift the platter off. Remove what's left of the old belt. Even if the old belt is still in one piece, chances are it's too stretched out to be of any use anymore. You will see a track for the belt on the underside of the platter. Put the new belt around this. It will be too loose be a little, but this is to allow for it to stretch and reach the motor spindle (the brass colored spindle off to the right on the now-exposed inner workings.

Along the rim of the underside of the platter you'll see a little plastic peg. Hook the belt onto this. Now, put the platter back on the silver spindle in such a way that the triangular hole where the belt is pulled away from its track by the bit you hooked onto that peg goes over the brass spindle. Once it's down and secure (you may have to wiggle it a little in order for the little gear on the underside to line up correctly) you should turn the platter clockwise. In theory, this should cause the brass spindle to pull the belt off the little peg and onto itself, thus connecting the belt with the drive motor. At this point, move the needle off its stand to see if the belt connected. If not, just repeat the belt-peg-spindle part. It may take a few tries, but it will work sooner or later. After it's turning properly, just replace the circlip that holds the platter down (you'll probably want a pair of pliars to push it on, it's a stiff little thing), and replace the plastic 45 adapter.

Good luck!

Take the metal platter off the center post. Flip the metal platter over & put the belt around the inner circle on the underside of the metal platter. Then put the metal platter (right side up) on the center post. Turn it until you can see the motor post (upper left corner) through the big opening in the metal platter. Pull the belt out from the platter to string it around the motor post, making sure it's seated in the groove.

Hi,

Hmm sounds advanced...

I'm no turntable guru, so I won't pretend to be anything more than I am.
I just bought an SL-BD22 myself, and at first it worked, but didn't turn; I soon realised the belt had slipped off.
I don't know if there's an official way to put it back, but I managed to put it back on within minute and it's working fine now (except the auto-return kicking in way too early, but that's another story; that's *my* problem...)

the way I did it was remove the platter mat, so you see the metal circle with holes in it, maybe you can see the belt through the holes ?
What I did was carefully then remove the metal disc, making sure I didn't pull on the belt (I tried feeling for the belt with my fingers then making sure it came off at the same time as the metal disc, to not stretch it)

Then, once metal plate and belt were off, I slid the belt around the inside of the metal disc - where it's supposed to be. It sort of just fit with only very little slack.
Since there are holes in the metal bit - here's the fiddly part - I placed the metal disc in front of me right-way-up, and put the belt (already around the inside of metal disc) also around one of my fingers poking throguh one of the holes from the top.
I then slowly and gently lowered the metal plate back to it's resting place, having my finger-with-the-belt-around-it right next to where the belt was supposed to go over the small cylinder shaped thing/pully/drive/whatever you call it.
Whilst lowered, I then slid the belt off of my finger and onto the pulley-thing.

There you go, the belt was around the motor pulley thing, and the metal plate. Put the platter mat back on, and switch it on to make sure it turns.
I've only had to do this once, but it worked first time.

Hope it works for you :)

The belt normally wraps around the bottom of the metal platter. Put the platter back on the turntable, and you'll see holes on opposite sides of the patter. Just pinch the belt out a little, and wrap around the motor shaft - should be a brass shaft assembly.

I FIGURED IT OUT! Here's how to fix the problem. 1. Remove the c clamp that holds your turntable in the box. Do this slowly so you don't over stretch or break your belt. 2. There are 3 screws holding the entire record player mechanism in the box. Take those out. 3. Look just under where the arm (the thing that holds the needle stylus) attaches to the mechanism. See that long wire rod that runs from that spot to just about the center of the turntable? It's being held at the arm by a little plastic piece that has a screw. The screw needs to be tightened. Once you tighten the screw, that will make is so that the arm has to be moved less to the right to start the record, and more to the left to turn it off. This makes it possible for you to hear the end of your songs! 4. Screw the mechanism back in the box (not too tight, you want those shock mounts to work). 5. To get the belt back on the wheel, first look under the wheel. See the big circle that is about half the size of the wheel? Place the belt around that. 6. Now look further out on the wheel. Do you see a plastic peg (actually 2 pegs....they are across from each other on the wheel)? Stretch the belt to one of the pegs. 7. Place the wheel back on the mechanism with the stretched part over the motor. Now spin the wheel slowly until the belt falls onto the motor. 8. Reattach the c clamp on the wheel and you're all set. Oh, I forgot to mention that you should put a record on and make sure you adjusted that screw under the arm enough. I had to do mine a couple of times. Hope this is helpful! Here's a video I found that better explains how to get the belt back on. http://www.youtube.com/watch?v=QaW84Z6GMVs

open up the top (where the record player is). Take off the pad, then remove the little c-clip surrounding the metal peg (in the center). Remove the turn table. Check underneath to see if the strap/belt is rather broken or has slipped off. If it broke, you have to go buy a new one. If it slipped off, put it back on. Put one end of the belt around the white plastic peg (the one that turns) and then the rest goes around the first outer ring on the bottom of the turn table (the middle one, between the outer edge and the middle insertion area. Its a real pain in the **** to do because it slips off a lot the first couple times...but you will get it eventually :) Once that is done put the table back on, test it, if it works put the c-clip back on (which is a lot harder than taking it off if I do say so myself lol) Put the rubber cover back on and Voila! You have a working turn table. For those with a broken belt use this as a replacement guide :)

Good luck guys and enjoy some good ol' Vinyl cause they are making a comeback!

Suggestion:

 

Pull rubber matt off TT. Use a small screw driver to pop off the small black "C" clip at base of steel record post. UNderneath plastic disc you will see the belt, and it loops on the metal post and over to the plastic barrel shaft to its right. Try this:

 

1. Using Non-gelatin based nail polish remover OR acetone (gotten from any hardware store), and a few Q-Tips, rub the belt inside and out along its entire length until you feel the tacky rubber feeling come back to the belt. You may also see the shiny surface come off the belt as you clean it. The shiney look is from belt slippage and its like a glazing. Also, if you notice any of this black glazing on the two belt posts, clkean them off as well.
2. If belt broken, replace with new by looping it back around the two posts under plastic TT platter.

If its truely a belt issue these two should solve it.

Remove the rubber mat and you will see two holes in the turntable. Put your fingers in these holes & using equal force pull up to release the turntable. The drive belt goes around the metal disk you will see below and around the drive pulley. Most likely it has just jumped off the pulley so hook it back over. Replace the turntable and gently rotate it a couple of revolutions, you can see the belt through the holes in the turntable. If all is seated OK power up & enjoy!
