Für dieses Gerät gibt es zwei verschiedene Laufwerke, deren Antriebsriemen verschiedene Längen und Querschnitte aufweisen.

Links: 1,5 x 1,5 mm Querschnitt, Durchmesser ca 27 mm.
Rechts: 1,8 x 1,8 mm Querschnitt, Durchmesser ca 43 mm.

Und wenn man den Riemen gewechselt hat, können auch gerade noch die Kontakte des Endschalters gereinigt werden, bevor sie Probleme bereiten. Z.B. wenn die Schublade auf Tastendruck zwar auffährt, aber dann sofort wieder selbsttätig schließt.
