I followed the Clymer manual and "very unclear" picture when I did my bearings but somehow wound up with an extra one of the large O-rings. Does anyone have a really good exploded view of the axle assembly? I swear one of these days I'm going to spring for the Honda Service Manual. I'm pretty fed up with the Clymer.

 

maybe the o ring that goes inside the brake caliper bracket?

 

go to www.yamahaoftroy.com and select "OEM Parts Finder" under ATV's select Honda, next a list of years will pop up select your year then your model. After all that select where the part is located and it will show complete breakdown of the pieces. It's AWESOME
