Gearbox bearing size?

[K-Brewer]

Need a little help with making sure I get the rite bearing, blew a bearing on the idle gear pin on my 210, its says in the instructions it's part No TD601022 5x8x2.5mm but looking in the parts list at the back it lists that part number being 5x8x3mm instead, does anyone have an idea which one it'll be?

something is screwy in the manual/website, I've had people come to me with a part number and it shows it being a 5x8x3, but its actually a 5x8x2.5. I really hope there new tranny case will use a bigger bearing on the top shaft though...
