Shark, Is it only me that has had this problem!

I hope someone can help, the soft roller is fine but where it has to attach to on the hoover base the rubbers on the belt drive chasssis have warn away! I’ve dismantled the whole thing and taken the relevant belt off (both belts are in excellent condition) but cannot take of the part the soft roller goes into, also I can not find any replacement part online or even a replacement part for the whole belt chassis area.

I can’t believe with all the millions of hoovers shark have sold I’m the first for this to happen to, an amazing hover and no way I want to replace the whole thing now I knew it solid be an easy fix. Hope someone can help! Thanks
