While riding out at the RAC, I bottomed-out on a rock,on one of the wide coal roads. Nothing alarming.

Ran fine back to trailer, that's when I noticed my skidplate gone, and chain pretty slack.

 

My lower pivot cross-bolt, dg skidplate, and adjuster locknuts (locknuts to tension chain) are all missing.... gone.

 

wtf.

 

I must've hit unobtanium with my skidplate.

 

Did I shear-off frame?

Can this be fixed, and where do I get the parts?

Ok, so I understand whats wrong with my banshee, and the parts are on order.

 

Question is... how the freakin' frack did this happen? The lower pivot bolt had to sheer-off on both ends, chain tensioners drop with the bolt ends, and then bolt shaft just falls out...?

 

How would the bolt simply come out, with the brake on one side, and the rear sprocket on the other?

(yes, bolt is accessed through the sprocket holes... but just fall out?)

Looks to me like your missing a roundhouse style swinger and a bearing carrier?

 

Crap... anyone got close-up pics of these parts? Trying to find everything I need off Ebay.

My service manual is black/white, and pics are hard to see.

So now I've gone through the service manual 3 times. There's no parts schematic for the rear chain adjustment/pivot area. WTF.

 

Anyone have a parts schematic and/or parts list for the rear swingarm section, which includes chain tensioner and pivot?

 

 

edit - found this...  Looks like all I need are 2 washers (part# 27 in this schematic).  Do they need to be anything special (locking washers, etc.)?
