questions on installing a Nexus hub.
 

ok I have the nexus hub prebuilt into the wheel that is sold by Harris Cyclery.

I just figure out that one of the metal circles is really a spring clip, and looks like it is for holding the sprocket in place. There is another black plastic ring that I am not sure where is goes.

Perhaps under the brass colored metal ring?

Ok never mind, simply looking at all of this in the morning, with a well rested brain is working much better then at the end of a really long, stressful day. :)

can't seem to get the lock ring to turn and lock. It is like I can't push it down enough to slip under the tabs that is locks under.

Any tips to doing this?

Maybe I have too many of the ring on it? There is a black plastic ring and a metal ring that are very similar in shape, do I need both on it? The metal ring seems to make it all too thick for the lock ring to go on. but then what is the metal ring for?

Why did you take it apart?

I did not take it apart. I received it with the cog off and I am simply trying to put on the last few parts (cog, snap ring, driver cap, cassette joint, and lockring). I just want to make sure I am doing things correctly.

Here is a post and some pictures that may help.

I have a question about 2 of the parts that came with the Nexus hub. the parts in question can be seen in the link below.

I think one of these might be the "driver cap" but I am not sure which one or if either of these is actually needed.

When I place the brass colored metal ring on the hub, it prevent me from getting the lock ring to lock in place on the cassette joint.

I can put on the smaller black ring and it seems to snap into place and I am able to get the lock on.

Please help me understand what these parts are and how I should use them.

Which Nexus hub is it? Have you found any instructions? Shimano has some on their site.
