Muller martini 1528 cover deck feeder

Can anyone tell me if this drive shaft has been rigged or it is from the factory. The belt/chord that runs under the V belt is getting chew up. I notice this moves around and think it could be the root of the problem. But, I do not see it in the parts book. It looks to me someone fix it with rubber tubing. Should it be solid?

 

ITs Ok no problem. it is original from factory.

Yes it’s original acts as a drive coupling for the belt.You should not have play there try changing the tubing.
