Hi all, I'm putting together my rear wheel but am stuck as to the fitting of the collar - according to diagrams and a post I read the collar goes inside the plate with the thick end nearest the hub. If I do that the collar is only held in place by the oil seal and there is a large gap between the hub/bearing and the collar. This would leave it free to rattle free of the oil seal and leave it rattling/spinning around the axle serving no purpose at all. Am I missing something here?

Welcome to the forum, yes something definitely wrong there (possibly something missing) when all the components are located onto the axle/spindle it needs to have no gaps as you can't tighten the whole assembly.
Essentially it needs all of the components to form a continuous tube along the spindle to allow correct assembly, that's the spacers and bearing inner races etc, otherwise as you finally tighten the wheel it will bend the swingarm inwards and some of the components will touch when they shouldn't.
Are you certain that all of the parts are there ?

You sure that's not the internal collar which locates into the wheel bearing?

Is the part you have #7 on the fiché?

Yes number 7 in the diagram. The internal spacer is in the wheel so spacers continuous from bearing to bearing. At present I have the wheel off with the collar on the wrong way around so will check again tomorrow but when I put it together the other day I looked at it going on both ways and as said couldn't see how it works with it in the correct position as still a gap. Will double check tomorrow in case I was having a bad head moment but it didn't seem right at the time due to noticeable gap but good to have confirmation of the correct way around. Watch this space...!

Just to confirm - if all is good then when axle is tightened up the collar will sit tight up against the wheel bearing one side and the other against the washer (number 46 in the diagram)?

From memory it fits big end touching the bearing with small dia through the seal

correct, I did that too just 3 weeks ago

No, it sits againts chain adjuster, number 65 in the diagram
From hub bearing : collar - chain adjuster (that sits on swingarm) - washer #46 and nut

All good now, must have had a bad head moment yesterday. Thanks for the replies, the extra info was good to know.
