If you are not familiar with such work, I don't recommend trying to install belt(s). Replacing belts may involve disassembly of mechanism parts and critical adjustments to follow. Take to a pro/tech

usually its a capstan drive belt. $10-18 for the belt & 30mins repair time - you'll be up &brunnin b4 you know it [email protected]

I also have an MR-929. The information that you need is in the 'Stereophonic 4 track stereo''. As stereo is only two tracks, there is another 2 tracks in addition to the one you are listening to. Wind the entire reel to the empty spool, and then play that. As you have to physically turn the reel over to do so, you should then hear the other tracks (or track, if recorded in mono).
I use my 929 to play my parents recording of my family from the late 60s, which were recorded on a valve (tube) Ferguson machine, which had a green "magic eye" level indicator, which as a child I found fascinating!

That's a rarity but easily fixed. Before pulling anything apart spray some penetrating oil (WD-40) or similar into a small container. Then with a cotton bud soak the tip in the penetrating oil and apply it to the base of the capstan where the bearing is. Allow this to sit for a few hours and even repeat it if it looks to have soaked the oil up. NOW, with the power lead out of the wall socket remove the top cover of the deck. You will have to remove a few knobs and mode switches too. Now see if you can rotate the capstan flywheel by hand. It might take a bit of pressure to get it to turn but once it does keep going until it starts to rotate freely.

By the way, check that the capstan drive belt is in one piece and not slipping first.

If it's running freely then reassemble the cover and other pieces tyhen put a few drops of light oil on the capstan bearing (sewing machine oil is ideal) Do this because penetrating oil will dry out after a while. That should fix it.

I'm assuming you know exactly how to thread the tape through the machine. Don't forget to position the stop lever on the upper side of the tape otherwise nothing will operate. If you are unsure about that write back and I will elaborate.
