I have a Sharkvac RC9740. Not XL. The tank tread belt that drives the wheels broke, and I want to replace it. I ordered a new belt from Amazon. I cannot find any directions or YouTube videos on how to do this. Has anyone done this before, and could give a few tips or hints?

Also, a secondary question. On Haywards website, there is an exploded parts diagram for my cleaner. The belt is given part number RCX23002. However, from looking at a picture of this belt and on Amazon, this is the wrong belt. The XL diagram uses belt RCX97501GR. Amazon describes this also as the belt for the XL. But it looks just like mine. So I ordered the XL belt. Has anyone else else replaced a belt on the Sharkvac RC9740, not XL? What belt did you buy?
