Mike, OK, You have the staff riveted on the balance. The roller doesn't fit as there is not enough lenght of the downside part of the staff. If I was You , I would turn the hub on the lathe so it will get thinner and let the roller get a little up on the staff. Sometimes it is easier to solve problems this way than wondering for several days what is not correct.

If only I had a lathe

So is it just the roller that's different between the 620 & 625?

Edit

Found these rollers on eBay and although not very good photos it looks to me like the 625 has a recess so sits further onto the seat?

The rollers look the same to me. I think the 620 pic is incorrect

Thinking the same as I notice on the documents provided that the roller is shown as the same part on the 620 & 625.
