Panasonic RX-S28 Walkman belt replacement (part 1)

At the end it plays tapes but sounds like a gear is grinding. Needs further inspection. I can’t until I get a power supply or a power bank so I can inspect without batteries. But if you just wanna replace the belt you can do that, I recommend though not to move or spin the pulleys from the original position as I suspect that’s what cause the grinding of the gears on mine because I moved them, I could be wrong. Thanks for watching
