So, just unscrew it and take out the belt inside? Unlike the typical turntable, it looks a bit hard to replace this belt.
Metal retainer bar???

Seeing is believing!
I've just found a Youtube clip on this. Step-by-step explanation for a beginner like me.
Aside from loosening the little screw, I've got to remove the idler wheel and stepped pulley, too, to take out the belt!
This is the information I've been looking for.

After you've cleaned the pulleys with alcohol, coat the new belt in pure talc powder before installation. It will quiet operation and help prevent the new belt from sticking to the pulleys.
Available from Amazon.
Coat the belt, shake it off and use a wooden stick to stretch the belt around the pulleys. A standard screwdriver will stick to the magnet.
Talc is a "dry lubricant". Not the same as "Baby Powder" which contains Cornstarch.
As you stretch a rubber band around a pulley, it "grabs" the pulley as it comes off and returns to its normal length. The talc prevents it from grabbing and allows the belt to slip off smoothly. This will reduce belt noise.

Very good information! Let me get one and use it. Thanks!

Sorry, I didn't watch that video but if that's what it's implying - find another one, preferably in English. No! Don't remove the idler and don't remove the stepped pulley, just thread the belt under the idler wheel and stretch it over the stepped pulley and motor pulley. A little guidance of the stepped pulley around with your finger will get it around both. This is really not any harder than tying shoes.
Really? You mean I should replace it from the underside if the turntable? Otherwise it's a bit hard to do it without removing the idler...
Well, it seems the belt has never been replaced.
It's in good working order, but the speed keeps changing bit even after I adjust it in about 20 minutes of running.
Agreed!
No need to remove anything. Only need to loosen and move that retaining tab out of the way. Remove the old belt and clean the pulleys with alcohol.
The idler wheel will get in the way as it partially covers the stepped pulley. Slip the new belt onto the stepped pulley first. Then stretch it around the motor pulley with a wooden stick. While your at it, clean the surfaces of the stepped pulley, the edge of the idler wheel and the inner rim of the platter.
I recently replaced the belt on my TD124 with an OEM Thorens TD124 belt, which arrived in days from HiFi.Heaven in Wisconsin. Model 6800581, folded measured length 163mm. Unfortunately, they are out of stock at this time.
I also purchased a Thakker belt from overseas as a backup but that took a few weeks to arrive.
It's in the bag with some talc until I need it.
Years back when I first restored my TD124 I tried a few different belts, they're not all the same! Some are not as wide, some are longer, some are shorter. I purchased a Thakker belt and it lasted many years.
I think the OEM Thorens belt might be superior. It's tight, but not too tight and it's silent. Keeps good speed too.
Edit:Corrected Belt model number

^^^What he said. You don't have to remove the idler wheel to change the belt! I don't speak Japanese, but I suspect the video may be about something other than changing the belt?
Alright, let me give it a try! Thanks.
By the way, I got this belt attached inside the platter. It looks like a surplus factory belt.

I thought that too until I heard a speed instability. It was a piano note and it wavered.
I thought belts worked until they didn't.
When I removed the platter I was shocked. The belt had shed material and left deposits on the surfaces of the pulleys. It was a mess in there.
Much improved since I replaced the belt. Recommend keeping a spare to avoid downtime.
Mine looks clean.
Measure it folded and keep it for your records.
