VHS Camcorder JVC GR-C7E von 1985, Reparatur

In diesem Video tausche Ich zwei Antriebsriemen für die Linsenmechanik der JVC GR-C7E. Den selben Camcorder findet man auch unter den Namen JVC GR-C7U.
Nach spätestens 30 Jahren leiern Riemen aus, oder lösen sich sogar auf und verwandeln sich in eine klebrige Masse. Die kaputten Riemen führen dazu, dass der Camcorder nicht mehr per Knopfdruck zoomen kann. Der automatische Fokus funktioniert dann auch nicht mehr.
Es gibt noch zwei andere Camcorder, die baugleich zu diesem hier sind: Die Toshiba SK-60 und die Zenith VM6200. Die Riemen lassen sich wahrscheinlich genau so austauschen wie hier.
Der Screenshot am Anfang zeigt Seite 75 aus der Zeitschrift Popular Science (Juni 1986).

Hi, these two belts are 1mm thick and have a diameter of 10mm. But there is also a big flat belt under the cassette mechanism, which I did not replace because it was still OK. I didn't measured it yet.

Thank you for the repair video, my JVC GR-C7U won't let me go into Monitor mode to record. It will turn on and read the NiCad batteries and my modded Lithium battery. But the door wouldn't open for me to put a tape in.
What do I do with my GR-C7U please?
Danke und du hast eine guten abent (Thank you and have a good evening) :D

Please can you tell me where you purchased the replacement belts? I'd like to repair my JVC GR-C7E as well. Thank you.

I got them from ebay, but i dont know the seller anymore. Often you can find belt kits there, also for VCRs, when you just type in the name of the product. The belts in this video are 1mm thick and have a diameter of 10mm. There is also a big flat belt under the cassette mechanism, which I did not replace because it was still OK.
